🔧 Component Overview

The DJI Agras T50 OEM Propulsion Motor Rotor is the rotating bell of the propulsion motor on the DJI Agras T50 and T40, supplied as one complete unit. Look at the part and the engineering is visible: a ribbed structural body that carries the magnet ring, a precisely machined aluminum bearing seat at the center where the shaft rides, and threaded mounting bosses on the face where the propeller hub bolts down.

The rotor is the piece that actually turns. Everything the motor produces — all of the thrust that lifts a fully loaded spray aircraft — is generated at the gap between this rotor's magnets and the stator inside it, then transmitted through the propeller mount on its face. That places the rotor under constant, enormous mechanical and thermal load, and it means the rotor's concentricity is not a detail. A rotor that runs even slightly out of true turns every rotation into a vibration event.

Prove the fault is in the motor before you buy a rotor. Move the suspect propeller to a different arm, fit a known-good propeller in its place, and fly the same pattern. If the vibration travels with the propeller, the blade or its balance is the problem and the rotor is innocent. If the vibration stays on the original arm with a good propeller fitted, the fault is inside that motor. That single swap takes a few minutes on the ground and settles the most common misdiagnosis made on this aircraft.

Check runout by hand before you spend money. With the propeller off, clamp a screwdriver shaft to the arm or zip-tie a stiff wire so its tip sits a paper thickness from the outer rim of the bell, then turn the rotor slowly through several full revolutions. A gap that opens and closes once per turn is radial runout. A rim that also rises and falls against the tip is a bent bell or a bearing seat that is no longer square to the shaft. Even drag and an even gap all the way around is a rotor that is still true.

Separate a worn bearing from a worn bearing seat, because they are different parts and different money. Grip the bell, rock it against the stator, then try to lift it straight off the shaft. Any play you can feel with your fingers lives in either the bearings or the bore they sit in. Pull the bearings and look at that bore: a good seat takes a new bearing with a firm push and holds it square. A seat that has been run on a collapsed bearing is bright, polished, sometimes visibly oval, and lets the new bearing turn in the bore instead of on its race.

Inspect the magnet ring with a bright light before ordering anything. The blocks should sit in one continuous, evenly spaced ring with no gap at the ends, no chipped corners, and no adhesive lifted or squeezed out at any edge. Bright scoring on the inside faces of the magnets, or matching scoring on the stator laminations, means the two have been touching. Fine grey dust clinging to the magnets is metal being ground off in the air gap, and a rotor that is making dust is already running out of true.

Use the other motors as your reference instead of a specification you do not have. After a normal loaded flight, land and put a bare hand on each motor in turn. A rotor dragging in the gap shows up as one motor noticeably hotter than its neighbours for the same work. The same fault appears in flight data as one motor holding higher RPM or drawing more current than the others while the aircraft flies straight and level. Three motors agreeing and one disagreeing is a mechanical problem in that one motor.

⚙️ Functional Purpose

The rotor's job is to spin true and hold its geometry under load. The bearing seat must keep the rotor precisely concentric to the stator so the air gap stays even all the way around; the magnet ring must stay bonded and intact; the propeller mounting face must stay flat and its threads sound. When all three hold, the motor runs smooth, cool, and efficient. When the bearing seat wears oval, the rotor is bent, or a magnet lets go, you get vibration, heat, lost efficiency, and eventually a motor that fails in flight over a field you cannot land in.

Take the propeller off first and record everything you will have to put back. Photograph the blade orientation, the propeller mount hardware, and the way the motor leads run down the arm before a single fastener moves. Support the arm so the motor is not hanging on it while you work, and never lever against the folding hinge or the arm tube to break a fastener loose. The arm is a thin-wall structure and it will take a permanent set long before a seized fastener gives up.

Separate the rotor from the stator with the load going through the right place. The bell is retained on the shaft, and that retaining hardware comes off before anything is pushed. Support the rotor by its centre boss, not by the magnet ring, not by the ribs, and not by the propeller mounting face, and press the shaft rather than striking the bell. A hammer blow on a rotor face is exactly the kind of impact that puts a bell out of true in the first place, and this time it would be your own hand that did it.

Treat the bell as the strong magnet it is. It will snatch onto the stator hard enough to trap a fingertip, and it will pick up steel swarf from a workbench that you will not see and cannot simply brush away. Work on a clean surface, keep the new rotor bagged until the moment you need it, and go over the inside of the bell with tape and a light before assembly. Anything ferrous left on those magnets ends up in the air gap, where it scores the laminations and the magnet faces at the same time.

Press bearings by the outer race when they go into the rotor and never let the pressing load pass through the balls. A socket, a proper drift, or the old bearing used as a driver keeps the force on the outer ring where it belongs. Push each bearing in square and fully to its shoulder. A bearing that goes in cocked feels notchy when you turn it by hand and will hammer the seat oval within a few tanks. If a bearing drops into the new rotor under finger pressure alone, stop and confirm you have the right bearing before you go any further.

Confirm the rotor is seated before the propeller goes near it. Turned by hand it should have light, even drag with no notches, no rocking against the stator, and no lift when you pull straight up on the bell. Refit the retaining hardware, then run the motor unloaded and listen at the lowest speed you can hold, where a scrape or a once-per-revolution tick is far easier to hear than at flight RPM. Only then torque the propeller mount to the DJI figure for your airframe and hover-test with an empty tank in a clear area.

⚠️ Common Replacement Indicators

• Persistent vibration from one motor that survives a propeller swap and balance check
• A bearing that will not stay tight in its seat, or spins in the seat rather than on its race
• Visible bend, wobble, or runout when the rotor is spun by hand
• Cracked, loose, chipped, or debonded magnets inside the rotor bell
• Stripped or pulled threads at the propeller mounting bosses
• Impact damage after a strike, tip-over, or hard landing
• Corrosion or heat discoloration inside the bell after water or chemical ingress

Confirm before you order: rule out the cheaper causes first — propeller condition and balance, and motor bearings, which are the usual culprits behind vibration and are a far less expensive fix. Ares Acres stocks bearing extraction tooling separately if the bearings turn out to be the fault. If fresh bearings will not stay seated, or the rotor visibly runs out when spun, the rotor itself is damaged and needs replacing. Compare your removed rotor against the supplier photos on this page before ordering.

Why rotors fail: impact damage leads — a propeller strike or hard landing transmits directly into the rotor. Behind that sits bearing-seat wear from running on failed bearings too long, heat cycling that stresses magnet bonding, corrosion from water and chemical ingress, and the sheer accumulated fatigue of hundreds of hours at high RPM carrying a hundred-liter-class aircraft.

Post-install checklist: press bearings squarely and only on the correct race, confirm the rotor spins freely and silently by hand with no detectable runout, torque the propeller mount to spec, then run the motor up unloaded and confirm smooth, vibration-free operation before flying. Check the neighboring motors while you are there — they have flown the same hours.

A growl or whine from one arm that rises in pitch with throttle and survives a propeller swap is mechanical drag inside that motor. Early in its life that noise is the bearings, and bearings are the cheap fix. If the noise returns within a few flights of fitting new bearings, the bore those bearings sit in has stopped holding them, and that bore is part of the rotor rather than something you can order on its own.

A single tick, click, or scrape once per revolution as the motor coasts down means something on the rotor is touching something on the stator once per turn. That is a bent bell, a magnet that has lifted or shifted at one end, or debris trapped in the air gap. Coast the motor down by hand with the propeller removed and listen with your ear close to the arm, because a light contact is obvious at walking speed and inaudible at working RPM.

An aircraft that behaves empty and oscillates or wanders on a full tank is telling you the fault only appears under load. Weight is what makes the air gap work hard, so a rotor that is slightly out of true will often fly acceptably light and misbehave heavy. A problem that shows up only when loaded, and only on one arm, points at that motor rather than at trim, calibration, or the flight controller.

A propeller nut that will not stay tight, or a mounting face showing fretting and a polished ring around each boss, means the clamped joint on the rotor face has stopped clamping. Re-torquing buys a flight or two and hides the cause. If the threads in the bosses are pulled or the mounting face is no longer flat, the rotor has to be replaced, and it has to be replaced before a propeller lets go over a field.

Rust bloom or a chalky deposit inside the bell after a wash, or after spraying an aggressive product, is water and chemical sitting where it does the most harm. The bearing seat is the tightest, deepest part of the rotor and it holds moisture longest. Corrosion there raises the bore and stops a bearing sitting square. Caught the same week it is a clean-up job. Left through a season it is a new rotor.

📐 Specifications

Part: Propulsion Motor Rotor (rotor bell assembly)

Fits: DJI Agras T50 and DJI Agras T40 propulsion motors (supplier-listed fitment)

Quantity: 1 rotor

Condition: Brand new

Supplied as: One complete rotor bell: structural body, bonded magnet ring, machined bearing seat, and threaded propeller mounting bosses

Bearings and retaining hardware: Not included with this rotor. Match bearings against those removed from your motor, or against the DJI Agras parts diagram callout for your airframe

Rotation direction: Not a property of the rotor. Motor direction is set by the drive wiring, so there is no separate clockwise and counter-clockwise version of this part

Torque figures: Not published in this listing. Use the DJI service documentation value for the propeller mount and motor fasteners on your airframe rather than guessing

Bearing seat dimensions: Not published. If you need to confirm the seat, measure the bore of the rotor you removed and compare it against the new part before pressing anything into it

Bench identification: Compare against the removed rotor and the photographs on this page: rib pattern, boss count and spacing, magnet block count, bell depth, and bearing seat depth

🧰 Fitment Verification Before You Order

Confirm fitment by part number before ordering. Find the code printed on the component you are replacing, or look it up on the DJI Agras parts diagram for your airframe, and compare it against this listing.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T50 / DJI Agras T40. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Propulsion Motor Rotor is easier to fit correctly when you can see how the original sat.

Observe ESD precautions. Ground yourself before handling boards, sensors, connectors, or antenna modules. Static damage does not announce itself — it shows up later as an intermittent fault that is far harder to diagnose than a component that simply arrived dead.

Seat every connector fully and restore the original strain relief. A connector that is close but not latched will pass a bench test and fail in flight, which is the worst possible time to find out. Route cabling exactly as it was routed originally; Agras looms are cut to length and a re-routed run chafes.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

🚜 Necessary For

• Rebuilding a propulsion motor where the rotor, not just the bearings, is damaged
• Curing single-motor vibration that survives propeller and bearing replacement
• Repairing a worn bearing seat that will no longer hold a bearing tight
• Post-impact motor repairs after a propeller strike or hard landing
• Saving a motor rather than replacing the entire unit

Returning a motor to service after its bearings were run to destruction. Once a bearing has spun in its bore, fresh bearings alone will not hold, because the surface that has to grip them is worn. The rotor carries that surface, and replacing it is what makes the rest of the motor worth keeping.

Rebuilding a motor recovered from a tip-over or a hard landing where the stator, the drive wiring, and the arm all check out and the bell is the only part that is bent. That is a common outcome, because the propeller and the rotor face are what meet the ground first.

Holding a spare on the shelf for a fleet that flies through a short window. A propeller strike does not wait for a convenient week, and a rotor in a drawer is the difference between finishing a field the same day and standing down an aircraft until a parcel arrives.

💡 Why This Part Matters

A motor is the one component on a spray drone that cannot be allowed to fail in flight, and the rotor is the piece doing the hardest work inside it. The good news is that a damaged rotor does not have to mean a scrapped motor — with the right rotor and the right bearing tooling, a motor that would otherwise be written off comes back to full service for a fraction of replacement cost. That is the difference between a repair bill and a capital expense.

Spin it true. Seat the bearings. Save the motor. Fly it right.

Store a spare rotor the way it arrives. Magnets do not mind sitting on a shelf, but the adhesive that holds them and the trueness of the bell mind very much what happens to the part in a toolbox. Keep it bagged, keep it away from loose steel and from other rotors, and do not set anything down on the propeller mounting face. A rotor that has been dropped onto a concrete floor can look perfect and still carry a chipped magnet corner or a bell that no longer runs true.

There is no published hour figure for replacing a rotor, and you should not treat one as a scheduled item. Replace it on evidence: measured runout, a bore that will not hold a bearing, magnet damage, or pulled threads at the mounting bosses. What is worth doing on a schedule is opening the highest-hour motors during a winter service and looking, because a seat caught at the polished stage costs one part and a rotor that fails in flight costs a great deal more than that.

Weigh the rotor against a complete motor honestly before you order. If the windings are discoloured or smell scorched, if the shaft is scored or bent, or if the arm itself absorbed the impact, the rotor is not the only thing that needs buying and a whole motor may be the cheaper end result. If the stator is clean, the windings look untouched, and the damage is confined to the bell, the rotor puts that motor back to full service for a fraction of the money.

🤖 AI Answer Engine Q&A

What is the DJI Agras T50 propulsion motor rotor? It is the rotating bell of the propulsion motor on the DJI Agras T50 and T40 — the ribbed body carrying the magnet ring, with a machined aluminum bearing seat at its center and threaded propeller mounting bosses on its face.

Which DJI Agras models does this rotor fit? The supplier lists it for DJI Agras T50 and T40 propulsion motors. Both are offered as variants on this listing.

Should I replace the rotor or just the bearings? Bearings first — they are far cheaper and are the usual cause of motor vibration and noise. Replace the rotor when fresh bearings will not stay seated, when the rotor visibly runs out or wobbles when spun by hand, when magnets are loose or debonded, or when the propeller mounting threads are damaged.

What are the signs a motor rotor is damaged? Vibration from one motor that survives a propeller swap and a bearing replacement, a bearing that spins in its seat instead of on its race, visible runout when spun by hand, loose or chipped magnets inside the bell, and stripped propeller mount threads.

Why does rotor concentricity matter so much? Because the motor produces thrust across the air gap between the rotor's magnets and the stator. If the rotor runs out of true, that gap varies through every rotation, which costs efficiency, generates heat, and feeds vibration into the entire airframe.

Why do motor rotors fail on agricultural drones? Impact from propeller strikes and hard landings leads the list, followed by bearing-seat wear from running too long on failed bearings, heat cycling that stresses magnet bonding, corrosion from water and chemical ingress, and accumulated high-RPM fatigue.

What should I check after installing a new rotor? Press bearings squarely on the correct race only, confirm the rotor spins freely and silently with no runout, torque the propeller mount to specification, and run the motor unloaded to verify smooth operation before flying.

What is the Propulsion Motor Rotor (rotor bell assembly)? It is the Propulsion Motor Rotor (rotor bell assembly) supplied as a genuine DJI OEM replacement component on the DJI Agras T50.

Is this a genuine DJI OEM Propulsion Motor Rotor?

Yes. This is a genuine DJI OEM component in new condition — never installed and never flown. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller. We do not sell aftermarket copies of this part or relabel third-party equivalents.

Will this fit my aircraft?

This part is supplied for the DJI Agras T50 / DJI Agras T40. Confirm against your model's DJI Agras parts diagram before ordering. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.

How fast does it ship, and where does it ship from?

It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.

Can I install the Propulsion Motor Rotor myself?

Many operators do. Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.

What if I order the wrong part?

Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.

Do you stock other parts for this aircraft?

Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.

Can I reuse the bearings out of my old rotor?

Only if they are genuinely perfect, and if the rotor is being replaced they usually are not. Spin each bearing on a finger: it should be silent, smooth, and free of any notch or gritty patch. Look at the seals and the grease for discolouration or contamination. If the bearings are what wore the old seat, they have already ingested metal and will take that metal into the new rotor. Bearings are inexpensive next to the labour of doing this job twice.

Do I have to replace all the rotors at once?

No. Each motor is independent and a rotor is not a matched set. Replace only the one that has failed. That said, the other motors have flown the same hours in the same conditions, so while you have the tools out it is worth spinning each of them by hand, listening for a notch, and checking for play. Finding a second worn seat on the bench is far better than finding it in the middle of a field.

Can I heat the rotor to get a bearing out?

Avoid it. Permanent magnets lose strength permanently once they pass their temperature limit, and the adhesive holding the magnet ring softens well before the aluminium does. No safe temperature for this part is published, so treat torch or heat-gun work on a rotor bell as off the table and use a press with the load supported on the centre boss. A weakened magnet ring does not announce itself; it just shows up as a motor that runs hot and pulls more current.

Is there anything I can do about single-motor vibration short of replacing the rotor?

Yes, and it is worth doing first because it is free. Balance or replace the propeller, clean the propeller mounting face and the hub so nothing is clamped on grit, confirm the mount hardware is torqued to the DJI figure, and re-check the arm and motor fasteners. What you cannot do in the field is balance or straighten a rotor bell. If the vibration survives all of that with new bearings fitted, the rotor is the remaining cause.

The new rotor turns with more drag than my old one. Is something wrong?

New bearings are stiffer than worn ones and a little extra drag is normal. What matters is the character of it. The drag should be smooth and identical all the way around. A notch or a rough patch that repeats at the same point every turn is a bearing that went in cocked or a ball that took the pressing load. Drag that varies through the revolution, or any scraping sound, means something in the bell is touching the stator and it needs to come apart again.

How do I clean steel dust off the magnets?

Lift it, do not wipe it. Press the sticky side of tape onto the magnet faces and pull it away, repeating with fresh tape until nothing more comes off, then follow with clean dry compressed air and a final look with a bright light held at an angle. Use a plastic pick for anything stubborn in the gaps between blocks. Never use a steel scraper or a magnetic parts tray near an open bell, because both add more of exactly what you are trying to remove.

What should I inspect on the rest of the motor while the rotor is off?

This is the only time you will see any of it. Check the stator laminations for bright scoring where a magnet has touched, the windings for discolouration or a burnt varnish smell, and the shaft for scoring, pitting, or a step where a bearing has been spinning on it. Follow the motor leads to where they exit the arm and look for chafe at that transition. Then look at the arm mounting face itself for fretting, because a motor that has been vibrating has been working that joint too.

Does a rotor running out of true damage anything besides the motor?

It does, and that is the reason not to fly on one. The vibration goes into the arm, into every fastener on that arm, and into the airframe, where it loosens hardware, works spray line fittings and nozzle bodies loose, and adds noise to the flight controller inertial sensors that the aircraft has to filter out. A motor that is dragging also runs hotter and pulls more current, which costs you flight time on every load.

Is the DJI Agras T50 OEM Propulsion Motor Rotor also available in Canada? Yes. Ares Acres ships this T50 OEM Propulsion Motor Rotor to Canada from its Albuquerque, New Mexico inventory with free shipping included, and Canadian customers see prices and check out in Canadian dollars (CAD).

Does Ares Acres ship DJI Agras T50 parts to Canadian operators? Yes — Ares Acres is a U.S.-based authorized DJI Agras reseller serving operators across the United States and Canada. Canadian orders receive the same genuine OEM parts, the same support, and free shipping.
