🇺🇸 U.S.A. FIRST

Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.

FREE & FAST Shipping is included for all U.S. customers.

We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.

Motor covers get cracked by propeller strikes, brittle from UV, and chewed by debris — then refitted anyway because the motor still spins. What follows is grit in the stator and chemical on the windings, and a motor rebuild that started with a cracked piece of plastic nobody replaced.

We ship the Motor Upper Cover fast to the U.S.A.

We use specialized technicians to verify and dispatch the Motor Upper Cover with Screws ordered.

Parts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.

That is why Ares Acres keeps hard-to-find OEM motors & escs in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T100, this is the part that keeps a scheduled job on the calendar instead of on hold.

🔧 Component Overview

The Motor Upper Cover is the vented top housing over the propulsion motor. It shields the stator and windings from debris, chemical mist and direct impact while its ventilation openings let the motor shed heat during sustained high-load flying.

The Motor Upper Cover supports:

• Debris exclusion from the stator
• Chemical mist shielding for windings
• Airflow for motor heat dissipation
• Impact protection for the motor top
• Correct propeller clearance geometry
• Restored factory motor enclosure
• Direct-fit replacement with hardware
• Increased aircraft readiness

Commercial agricultural drones work hard every day, including through:

• Crop spraying missions
• Full-load thrust on every pass
• High-tempo fill-and-fly cycles
• Long-duration spraying campaigns
• Daily commercial deployments
• Fleet operations
• High-acreage contract work
• Repeated transport and handling

Throughout these operations, this is routinely exposed to:

• Chemical overspray and mist
• Dust and abrasive particulate
• Propeller strike and impact damage
• UV degradation and embrittlement
• Motor heat cycling
• Pressure washing and rinsing
• Seasonal intensive operation
• Long commercial operating hours

The Motor Upper Cover helps maintain:

• Clean, debris-free stator
• Chemical protection for windings
• Correct motor cooling airflow
• Protection against impact damage
• Long motor service life
• Consistent propulsion performance
• Full aircraft availability
• Predictable service intervals

The cover caps the top of the propulsion motor and is held by its own small screw set into bosses in the motor housing. Under it sit the stator laminations, the windings and their phase leads, and the upper bearing area. Above it is the propeller hub, so the cover lives inside the blade sweep and in the downwash of everything the rotors pick up off the crop and the ground. It is also the highest sun-facing plastic on the airframe apart from the props.

The ventilation openings are what make it more than a lid. Air moving through them is how the motor sheds the heat it makes carrying a loaded T100 down a long pass. That makes those openings the weak point in two directions: they are where dried spray mix and dust collect, and they are the thin webs of material where a crack finds somewhere to travel.

⚙️ Functional Purpose

The Motor Upper Cover is designed to restore and maintain the protective enclosure over the DJI Agras T100 propulsion motor.

The part helps:

• Restore the factory motor enclosure
• Replace a cracked or impacted cover
• Stop debris ingress into the stator
• Shield windings from chemical mist
• Restore correct cooling airflow
• Complete a motor rebuild
• Remove a known contamination path
• Return the motor to specification
• Keep a low-cost protective part on the shelf
• Maintain propulsion reliability through the season

Going without may contribute to:

• Debris and grit reaching the stator
• Chemical corrosion on windings
• Reduced motor cooling and heat soak
• Accelerated bearing contamination
• Expensive motor replacement
• Unplanned downtime
• Missed spray windows
• Reduced fleet availability

The cover does not seal the motor and is not meant to. Airflow has to get in. What it stops is the trajectory that matters: material thrown up by the rotors or kicked off the terrain, arriving fast from above and from the side, straight at the winding pack.

Because it is not a seal, its condition matters more than it looks like it should. A hairline crack does not leak the way a gasket leaks. It moves where air enters and routes grit-laden air somewhere the design never sent it. A cover that is still on there is not the same as a cover that is still working.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Cracking or splitting in the cover
• Impact damage from a propeller strike
• Brittleness or chalking from UV exposure
• Blocked or deformed ventilation openings
• Debris found inside the motor
• Chemical residue on the stator
• Stripped or damaged screw bosses
• Missing cover after prior service
• Motor running hotter than its neighbours
• Scheduled propulsion inspection reached

Covers are sacrificial. They are designed to take the impact, UV and chemical exposure that would otherwise reach the motor, which means they degrade on a schedule while the motor does not. Replacing a compromised cover is routine maintenance, not a repair.

A hairline crack running out of one of the screw holes. This is how these covers usually start to go: the boss is where clamping load, vibration, and any knock on the rim all end up. Once the crack reaches the nearest ventilation opening it steps slot to slot and speeds up.

Chalking, or a dull film on the top surface that wipes off gray on your hand. That is UV breakdown of the surface and a warning about the material under it. A chalked cover shatters where a fresh one would scuff.

The cover no longer sits flat. Run a fingernail around the joint with the motor. A cover standing proud on one side, usually after a strike or after one screw was pulled down harder than the rest, opens a debris path exactly where you cannot see it.

Dried spray residue packed into the ventilation openings that will not wash out. Blocked vents raise motor temperature under precisely the loads where you want headroom, and the crust holds chemical and moisture against the housing between jobs.

🧰 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 T100. 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 Motor Upper Cover with Screws is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

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.

💡 Why This Component Matters

Motors are among the most expensive consumables on the aircraft, and almost everything that kills them early comes in from outside: grit, chemical, water, impact. The cover is the barrier. Replacing it costs a fraction of the motor and takes minutes with the screws supplied.

The Motor Upper Cover helps maintain:

• Clean, debris-free stator
• Chemical protection for windings
• Correct motor cooling airflow
• Protection against impact damage
• Long motor service life
• Consistent propulsion performance
• Full aircraft availability
• Predictable service intervals

Without it, operators risk:

• Contamination destroying a motor
• Chemical corrosion on windings
• Heat soak and reduced thrust margin
• Emergency repair premiums
• Downtime during peak season
• Cascading bearing and stator damage
• Reduced fleet availability
• Reduced return on investment

For practical, hardworking operators, the value is simple:

Protect the motor. Protect the aircraft. Protect the mission. Protect the season.

The real question is whether the cover is worth doing on its own or whether the motor is already compromised. Fit the cover, but do not stop there. If the aircraft flew any length of time with a crack, the cover is the symptom and the stator is where the damage went. Blow the winding pack out with low-pressure air, look for gritty film between the laminations, and turn the motor by hand feeling for the notchy rasp that says the bearing already ate something.

The other decision is one or all. Impact damage is local: one strike, one cover. Age is not. UV and chemical exposure reach every motor on the airframe at the same rate, so if one cover has gone chalky and brittle the rest are close behind. Changing them as a set at a scheduled service keeps it from coming up in the middle of a field.

The cover is cracked but the motor still runs normally. Can I finish the season?

The motor running normally is not evidence the cover is doing anything. A crack changes where air and debris get in, and that damage is cumulative and quiet: grit bedding into the winding pack, chemical on insulation, a bearing picking up contamination. By the time the motor tells you, you are buying a motor.

Can I glue or tape a cracked cover to get through a job?

Tape over ventilation openings is worse than the crack, because you have traded a debris path for a heat problem on a motor already working hard. Adhesive on a part that vibrates, heat-cycles, and gets washed does not hold, and when it lets go the crack restarts at the repair.

There is a chalky film on top of the cover. Is that chemical or sun?

Usually sun. UV chalking is even, sits on upward-facing surfaces, and comes off as a fine powder while the shaded underside still looks new. Chemical staining is patchy, concentrates around the vents and wherever mix ran off and dried, and leaves a hard crust rather than a powder.

One cover is damaged. Should I do the others at the same time?

If it was a strike, no, that is one event on one arm. If it is age, check the others first. Flex the rim gently on an undamaged cover: fresh material gives a little and returns, aged material feels hard and dry. Covers that flew the same hours in the same sun fail within a short span of each other.
