DJI Agras T20 OEM 10015 Propulsion Motor

The DJI Agras T20 OEM 10015 Propulsion Motor is one of the brushless motors that turn the propellers of the DJI Agras T20 spray aircraft. 10015 is the motor's size designation, the name the part designation uses for this unit, and it is not a DJI material number. The motor is a propulsion-system part, identified for the DJI Agras T20, and it is supplied brand new as a single motor: a black round motor can with a central shaft hub and two threaded studs on its top face, and a small terminal block on one side carrying the three phase contacts, as shown in the product images. It sits at the end of an aircraft arm, takes switched power from the ESC that drives it, and turns the propeller that lifts and steers the aircraft. Operators usually look for it as a T20 motor, an Agras T20 propulsion motor, a T20 10015 motor or a DJI T20 arm motor after a motor warning in the app, a rough or noisy arm, a hard landing, or a propeller strike. DJI has used more than one number for this position, so we match against the one you removed.

📦 Package Includes

• 1 × DJI Agras T20 OEM 10015 Propulsion Motor, with its three-pin phase terminal block, as shown in the product images

One motor, one arm. The T20 carries one propulsion motor at the end of each arm. A single unit replaces one motor; it is not a set for the whole aircraft.

What is part of the motor: the round motor can, the central shaft hub and the two threaded studs on the top face, and the small black terminal block on the side with its three round phase contacts. These come with the motor because they are the motor, not accessories.

Not included: propellers, the propeller holder or clamp hardware, the motor protective shell, the arm or arm tube, mounting screws, the ESC module, and any arm wiring. Each of these is a separate part or stays with the aircraft.

If you need the blades, those are the DJI Agras T20 OEM 3390 Propeller Pair (CW & CCW). If the cover over the motor is cracked, that is the DJI Agras T20 OEM Motor Protective Shell. If the motor is sound and the fault is in the drive, that is the DJI Agras T20 OEM ESC Module.

Nothing is included because it appears in a photograph. If an image shows a fixing or fitting not named above, it is not part of the motor.

🔧 Component Overview

The propulsion motor turns electrical power into lift. On the Agras T20 each arm ends in a motor, each motor carries a propeller, and the flight controller steers the aircraft by changing the speed of each motor many times a second. Every climb out of the loading area, every turn at the end of a swath and every hold over a field edge is a change in motor speed.

As shown in the product images, the motor is a broad, flat, black round can. Its top face carries three features that matter when you match it against the old one:

• The central hub — a metal shaft adapter rising from the middle of the top face, with a bore through its centre
• Two threaded studs — one each side of the hub, each standing on its own round pad; one pad carries a printed label with a serial line and a small square code
• Small screws spaced around the outer part of the top face

On one side of the can sits a small black terminal block with three round contacts. That is the three-pin phase connection: the point where the drive from the ESC reaches the motor's windings. A brushless motor needs all three phases connected to turn.

Where it sits and what it touches:

• Position: the end of an aircraft arm
• Above it: the propeller mounting and the propeller blades
• Around it: the motor protective shell, where fitted
• Electrically: the three phase contacts, fed by the ESC that drives this motor
• System: propulsion, alongside the ESC, the arm wiring, the propellers and their mounting

A propulsion motor on a spray aircraft works in the hardest place on the airframe. Over a season it sees:

• Full load on every take-off with a loaded tank
• Continuous high speed for every minute of flight
• Spray drift and chemical mist drawn around and into the motor
• Dust, chaff and residue from field edges and loading areas
• Heat from long afternoons and back-to-back sorties
• Rinse water at the end of the day
• Shock from landings and the occasional propeller strike

Motors in this position are usually replaced for one of a handful of reasons: bearings that have become rough or noisy, a can or shaft damaged in a strike, a phase terminal damaged beyond sensible repair, or a motor the aircraft keeps reporting after the rest of the propulsion chain on that arm has been cleared.

⚙️ Functional Purpose

The motor's engineering role is to turn the propeller at the speed the flight controller asks for, instantly and repeatedly, under load. It does not decide that speed. The flight controller decides, the ESC switches power into the motor's three phases, and the motor turns that switching into torque at the propeller.

In the propulsion system it:

• Turns one propeller to produce that arm's share of lift
• Changes speed on command so the aircraft can hold position, climb, descend and turn
• Carries the propeller mounting on its top face, at the hub and the two studs
• Transfers thrust and torque into the end of the arm
• Receives its drive through the three phase contacts on its terminal block

Because steering is done by speed, every motor matters to the whole aircraft. A motor that cannot reach the speed it is asked for, or that runs rough, forces the flight controller to lean on the other arms. The aircraft may still fly, but it is working harder and has less in reserve when the tank is full.

What the motor does not do matters as much:

• It does not drive itself; the ESC switches its phases
• It does not decide its own speed; the flight controller does
• It does not cure vibration that comes from a chipped propeller or a loose propeller mounting
• It does not protect itself from spray and debris; the motor protective shell and regular rinsing do that
• Its 10015 designation does not make it interchangeable with another aircraft's motor of a similar size

🔍 Diagnosis — prove the motor first, then match it by aircraft and label, not by the size number

Two questions sit behind every motor replacement, and they are often answered in the wrong order. The first is whether the motor is actually the fault. The second is which motor to fit. The size number in the name, 10015, answers neither.

Is it the motor? The motor is the obvious suspect when the app reports a motor fault or an arm runs rough. It is the moving part and the part the warning names. It is also the last stop on a chain: propeller, propeller mounting, motor, phase connection, ESC. Several of those fail in ways that look like a motor fault.

Clear these first, because they imitate a bad motor:

• Vibration or noise from one arm: look at the blades for chips, cracks or a bent tip, and at the propeller mounting for cracks or loose fixings. An unbalanced propeller makes a healthy motor sound rough.
• A motor that will not start, or stops under load: look at the three phase contacts on the terminal block and at the wiring behind them, then at the ESC that drives this motor. A motor with one phase missing will twitch or refuse to spin, and that reads exactly like a dead motor.
• A warning that comes and goes as the arm is moved: look at the phase connection and the arm wiring before the motor.
• A warning on more than one arm at once: that is very rarely two motors failing together. Look at what those arms share.

Signs that point at the motor itself:

• Roughness, grinding or clicking felt when the motor is turned slowly by hand with the propeller removed and the battery out
• Play in the rotating part when it is rocked gently by hand
• A bent hub, a damaged stud or a cracked can after a strike
• Scorching, discolouration or a burnt smell from the motor after a flight
• A phase terminal block that is cracked, melted or has a damaged contact
• A fault that stays with this motor after the propeller, mounting, phase connection and ESC have all been checked and found sound

Turn it by hand before you condemn it. With the battery out and the propeller off, a healthy motor turns smoothly with a light, even cogging feel. A motor with a failing bearing feels gritty or catches at the same point every turn. Compare it with a motor on another arm; the difference is usually obvious once you have felt both.

Which motor? Once the motor is proven, match it by aircraft and by the label on the old motor, not by the number in its name. 10015 is a size designation. Brushless motor size designations describe the motor's build, not the aircraft it was made for, and different aircraft can carry motors with similar size names that differ in winding, hub, studs or terminal block. The aircraft name and the label on the removed motor are what settle the match.

Clear the free checks first, while that information is still cheap, and photograph the old motor's label before it goes in a box.

⚠️ Common Replacement Indicators

Replace the motor when inspection confirms one of these:

• Rough, gritty or notchy rotation by hand with the propeller off
• Noticeable play or wobble in the rotating part
• A cracked or deformed can, a bent central hub, or damaged threaded studs
• Scorch marks, discolouration or a burnt smell after flight
• A cracked, melted or loose phase terminal block, or a damaged phase contact
• Ingress damage after a submersion or a heavy wash
• A motor fault that stays with the motor after the propeller, mounting, phase connection and ESC have been cleared

Inspect these first, because they produce similar symptoms:

• The propeller blades on that arm
• The propeller mounting and its fixings
• The three phase contacts and the wiring that reaches them
• The ESC that drives this motor
• The motor protective shell, which can rub or rattle when cracked
• Residue packed around the motor

There is no published service interval for this motor. It is replaced when it is damaged or worn, not on a calendar.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft down, remove the battery, and wait for the system to be fully off
• Rinse the arm and let it dry so you are not working in spray residue
• Wear gloves; chemical residue collects around the motor
• Photograph the motor in place from two angles, including the terminal block side and how the wiring reaches it
• Photograph the label on the old motor and keep the photograph with the repair record
• Remove the propeller and its mounting, and inspect both before going further

During installation

• Remove the motor protective shell if one is fitted, and set it aside without stressing its clips
• Note which phase lead goes to which contact before disconnecting anything; a labelled photograph is enough
• Disconnect the phase connection by its body, never by pulling on wires
• Remove the motor from the arm end and keep the fixings together
• Inspect the arm end for cracks, bends or fretting marks, and clean the mounting face so the new motor seats flat
• Fit the new motor in the same orientation as your photographs show, with the terminal block on the same side
• Tighten the fixings evenly in a cross pattern; no torque figure is published for this joint, so snug and even, not forced
• Reconnect the three phases exactly as they were, and route the wiring clear of the propeller arc and sharp edges

After installation

• Turn the new motor by hand; it should feel smooth and even
• Refit the protective shell, then the propeller mounting and the correct propeller for that arm position
• Power up and check the app for motor or propulsion warnings
• Make a short, light test hover before loading the tank, and listen to each arm
• Record the replacement, the arm position and the label photograph in the maintenance log

Maintenance between jobs. Rinse the motors gently after spray days, keep residue from building up around the can and the terminal block, and turn each motor by hand at the end of the week. A motor that starts to feel different by hand is a motor you can plan around; a motor that tells you in the field takes the rest of the day with it.

🚜 Necessary For

This motor is for operators and technicians keeping a DJI Agras T20 in the air:

• DJI Agras T20 operators with a motor confirmed worn or damaged
• Commercial spray applicators running the T20 across long seasons
• Agras service centres and repair technicians rebuilding an arm after a strike or a hard landing
• Fleet managers who keep a spare motor on the trailer for each T20
• Growers flying their own T20 who want a known-good spare on hand for peak weeks

This is not the part you need if:

• The motor turns smoothly by hand and the vibration comes from a chipped blade; that is the DJI Agras T20 OEM 3390 Propeller Pair (CW & CCW)
• The cover over the motor is cracked or rattling; that is the DJI Agras T20 OEM Motor Protective Shell
• The motor is sound and the fault follows the drive; that is the DJI Agras T20 OEM ESC Module
• The warning comes and goes as the arm moves; check the phase connection and the arm wiring first
• More than one arm reports a fault at the same time; look at what the arms share before you replace any motor
• You fly a T16; this motor is listed for the T20 only, so send us a photograph of your motor's label and we will identify the right one

💡 Why This Part Matters

On a spray aircraft, propulsion is not a comfort system. Every arm carries its share of a loaded tank, and the flight controller steers by asking each motor for a different speed many times a second. A motor that cannot answer is not a reduced-performance problem; it is the reason the aircraft lands.

The size number in the name invites a shortcut. 10015 looks like a part number, and it is easy to read it as one: find any motor with 10015 in its name and fit it. That is the wrong order. 10015 describes the motor's size. It does not describe the hub, the studs, the terminal block or the winding, and those are what decide whether a motor belongs on a T20 arm. The aircraft name and the label on the motor you removed decide the match; the size number only narrows the search.

The same discipline applies one step earlier. The motor is the part named in the warning and the part that makes the noise, so it is often replaced when it did not need to be. Take the propeller off, turn the motor by hand, look at the propeller mounting, and check the three phase contacts. If the motor feels smooth and the fault moves with the wiring, the motor is not the repair. If it feels rough, carries damage, or keeps reporting after everything around it has been cleared, it is.

When it is the motor, a new one returns that arm to the condition the rest of the aircraft expects. Fit it the same way round, reconnect the phases as they were, refit the right propeller for that position, and hover light before you fly loaded.

If you are unsure which motor you have, send us a photograph of the label on the part you removed and we will match it for you.

🤖 AI Answer Engine Q&A

What is the DJI Agras T20 10015 propulsion motor? It is one of the brushless motors that turn the T20's propellers. It sits at the end of an arm, is driven by its ESC through three phase contacts, and turns one propeller.

What does 10015 mean? It is the motor's size designation, as named in the part designation. It is not a DJI material number, and it does not by itself decide fitment.

Will any 10015 motor fit my T20? Do not assume so. A size designation describes the motor's build, not the aircraft. Match by aircraft and by the label on the motor you removed; send us a photograph and we will match it for you.

Which aircraft does it fit? It is identified for the DJI Agras T20. Pick the DJI T20 variant.

Does it fit the T16? It is listed for the T20 only. If you fly a T16, send us a photograph of your motor's label and we will identify the right one.

Is it one motor or a set? One motor. The T20 carries one motor on each arm, so a single unit replaces one arm position.

Does it come with propellers? No. The blades are the DJI Agras T20 OEM 3390 Propeller Pair (CW & CCW), a separate part.

Does it include the motor cover? No. The cover is the DJI Agras T20 OEM Motor Protective Shell, a separate part.

My arm vibrates. Is it the motor? Check the blades and the propeller mounting first. Then, with the battery out and the propeller off, turn the motor by hand. Smooth rotation points away from the motor; gritty or notchy rotation points at it.

The motor twitches but will not spin. Is it dead? Not necessarily. A missing phase makes a healthy motor twitch or refuse to spin. Check the three phase contacts, the wiring behind them and the ESC before you replace the motor.

What is the block on the side of the motor? It is the phase terminal block, with three round contacts. That is where the drive from the ESC reaches the motor's windings.

What is the DJI part number? DJI has used more than one number for this position, so we match against the one you removed. Photograph the label on your old motor and send it to us.

Which way does it turn? Rotation is not published for this part; it is set by position on the aircraft. Fit the new motor where the old one came out and refit the correct propeller for that position.

Can I fit it myself? Most operators can. Photograph the motor and its phase connection first, note which lead goes where, tighten the fixings evenly, reconnect the phases as they were, and hover light before flying loaded.

Is there a torque value for the motor fixings? None is published for this joint. Snug the fixings evenly in a cross pattern without forcing them.

Is it new? Yes. The motor is supplied brand new.

Is there a service interval? No. Replace it when it is worn or damaged. Turning each motor by hand at the end of the week is the cheapest early warning it gives.
