DJI Agras T30 OEM ESC Module

The DJI Agras T30 OEM ESC Module is the electronic speed controller that drives one propulsion motor on the DJI Agras T30 and T10 spray aircraft. ESC stands for electronic speed controller: the module takes power and a speed command from the aircraft and switches that power through the motor's three phases, so the motor turns at the speed the flight controller asks for. It is a propulsion-system part, identified for the DJI Agras T30 and T10, and it is supplied brand new as one complete module: a dark grey housing with a clear cap at one end, a QR code and a small label on its face, a finned section across its lower half and a stepped connector block at its narrow end, as shown in the product images. Operators look for it as a T30 ESC, a T10 ESC, an Agras T30 motor controller or a T30 T10 electric control module after a motor or propulsion warning in the app, an arm that will not drive, or a module that has run hot or taken a strike. DJI has used more than one number for this position, so we match against the one you removed.

📦 Package Includes

• 1 × DJI Agras T30 OEM ESC Module, as shown in the product images

One module, one motor position. Each propulsion motor has its own ESC. The T30 flies on six motors and the T10 on four, so one module replaces one of six positions on a T30 or one of four on a T10. It is not a set for the aircraft.

What it is: the complete module in its housing, with its clear end cap, finned section and connector block, as one unit. It is not a bare circuit board, and it is not a motor.

Not included: the propulsion motor, propellers, arm wiring or cables, mounting screws, thermal pads, and any frame or arm hardware. Each of these is a separate part or stays with the aircraft.

This module is for the T30 and T10. The DJI Agras T20 OEM ESC Module is a different part for a different aircraft; if you fly a T20 or T16, that is the module you need.

Nothing is included because it appears in a photograph. If an image shows anything not named above, it is not part of the module.

🔧 Component Overview

A brushless motor cannot run itself. Something has to switch current through its three windings in the right order, at the right moment, thousands of times a second, and keep doing it while the flight controller changes its mind about speed many times a second. On the Agras T30 and T10 that work belongs to the ESC module, one per motor.

As shown in the product images, the module is a long, dark grey housing. Its visible features:

• A clear cap across one end of the housing
• A printed QR code on the face just below that cap
• A raised rectangular plate on the face carrying a small white label
• A finned section of five deep fins across the lower half, where heat leaves the module
• A stepped connector block at the narrow end, with gold contacts at its tip
• A screw-mounted plate on the back, where the module is fixed in place

Where it sits and what it touches:

• Position: on the propulsion side of the aircraft, one module per motor position
• Upstream: the aircraft's power supply and the flight controller's speed command
• Downstream: the three phases of one propulsion motor
• System: propulsion, alongside the motors, the arm wiring, the propellers and their mounting

On a spray aircraft the ESC works in heat, vibration and chemical mist. Over a season it sees:

• High current every time the aircraft lifts a full tank or hopper
• Constant changes in demand, because the aircraft steers by motor speed
• Heat from its own switching, added to afternoon sun and back-to-back sorties
• Spray drift and residue settling on the housing and between the fins
• Rinse water at the end of the day
• Vibration through the frame on every flight
• Shock from hard landings and propeller strikes

Modules in this position are replaced for a handful of reasons: one that has failed and will not drive its motor, one that cuts out under load or after running hot, a cracked housing or damaged connector block after a strike, or ingress after a heavy wash or a submersion.

⚙️ Functional Purpose

The ESC's job is translation. The flight controller decides how fast each motor should turn. The ESC turns that decision into switched current in the motor's three windings, so the motor reaches that speed and holds it under load.

In the propulsion system it:

• Takes power from the aircraft through its connector block
• Takes the speed command for its own motor
• Switches current through the motor's three phases in sequence
• Follows fast changes in demand as the aircraft climbs, turns and holds position
• Sheds the heat of that switching through its fins

Because the aircraft steers by changing the speed of each motor against the others, each ESC carries a share of the whole aircraft's control. On a six-motor T30 one module is a sixth of the drive; on a four-motor T10 it is a quarter. Either way, a module that cannot drive its motor takes that position out of the flight controller's hands.

What the ESC does not do:

• It does not turn the propeller; the motor does
• It does not decide motor speed; the flight controller does
• It does not cure a motor with worn bearings or a damaged can
• It does not cure vibration from a chipped blade or loose propeller mounting
• It does not keep itself cool if its fins are packed with residue; that is maintenance

🔍 Diagnosis — count the positions that are down before you count the modules to buy

The first useful number in any propulsion fault is how many positions are affected. The T30 has six motors and six ESC modules; the T10 has four of each. Each module is independent of the others at the output side. So the count tells you where to look.

One position down, the rest normal: the fault lives somewhere on that one position: its module, its motor, its propeller or the connections between them. One module is the right number to consider.

Two or more positions down together: independent modules rarely fail in the same minute. Look at what those positions share before buying several modules: power supply, wiring runs, connections, a recent wash or a hard landing that hit more than one arm.

Every position faulting at once: the cause is almost certainly upstream of the ESCs. Replacing modules will not clear it.

Then separate the module from the motor on the one position that is down. Signs that point away from the motor and toward the ESC:

• The motor turns smoothly and evenly by hand with the propeller off and the battery out
• The motor twitches, stutters or refuses to spin when commanded, yet feels perfect by hand
• The position cuts out after hard work on a hot day, then recovers once the module cools
• Scorching, discolouration or a burnt smell at the module rather than at the motor
• A cracked housing, a damaged connector block or residue inside the clear cap after a wash
• A fault that stays at this position after a known-good motor has been fitted there

Meter the motor. With the battery out and the motor disconnected from the ESC, measure resistance between each pair of the motor's three phase contacts. A healthy brushless motor reads the same low value on all three pairs. Matching readings and smooth rotation by hand put the module next in line.

Clear these first, because they imitate a bad ESC:

• A loose or corroded connection at the connector block: the module cannot drive through a bad joint
• A damaged arm cable: a chafed or crushed run behaves like an intermittent module
• A motor with a shorted winding: uneven meter readings point at the motor, not the module
• Fins packed with residue: a healthy module that cannot shed heat cuts out like a failing one; clean and retest

Count first, then meter. Those two checks, done while that information is still cheap, usually tell you whether the aircraft needs one module, something other than a module, or something every module shares.

⚠️ Common Replacement Indicators

Replace the ESC module when inspection confirms one of these on a single position:

• The module will not drive a motor whose windings meter evenly and that turns smoothly by hand
• The fault stays at this position after a known-good motor has been fitted
• Repeated cut-outs under load with clean fins and sound connections
• Scorch marks, discolouration, swelling or a burnt smell at the module
• A cracked housing, a cracked or clouded end cap with moisture behind it, or a damaged connector block
• Liquid or residue inside the module after a wash or a submersion

Inspect these first, because they produce similar symptoms:

• The motor on that position, by hand and with a meter
• The connector block and the contacts it mates with
• The arm wiring and any cable that flexes as the arms fold
• Residue between the module's fins
• The propeller blades and mounting, if the complaint is vibration rather than loss of drive
• Whatever several positions share, if more than one is down

There is no published service interval for this module. It is replaced when it has failed or been damaged, not on a calendar.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft down, remove the battery, and wait until the system is fully off before touching any connection
• Rinse and dry the area around the module so you are not working in spray residue
• Count the positions that are down and prove the fault on the one you are replacing: turn the motor by hand and meter its three phases
• Note which position the module came from, by arm, so the record and any follow-up check are on the right motor
• Photograph the old module in place from the face side and from the connector end
• Lay the new module beside the old one and compare outline, end cap, fins, connector block and mounting plate

During installation

• Release the module's fixings at its mounting plate and keep the screws together
• Withdraw the module straight off its connector, holding the housing, not any wire
• Look into the mating connector for bent contacts, corrosion or residue and clean it dry if needed
• Seat the new module straight onto its connector in the same orientation your photographs show, without forcing it at an angle
• Refit the fixings evenly; no torque figure is published for these fixings, so snug them without cracking the plate
• Check that wiring near the module is routed as it was, clear of hot surfaces, sharp edges and the propeller arc

After installation

• Confirm the module is fully seated and the fixings are tight before fitting the battery
• Power up and check the app for motor, ESC or propulsion warnings
• With the propeller off and the aircraft secured, confirm the motor responds where the app allows a motor check
• Refit the propeller for that position and make a short, light test hover before loading the tank
• After the first full sortie, check the module for unusual heat near the fins, compared with the modules on the other arms
• Record the replacement and the position in the maintenance log

Maintenance between jobs. The module sheds its heat through five deep fins, and spray residue fills fins faster than anything else on the aircraft. Rinse the housing gently after spray days, keep the fins open, look through the clear cap for moisture, and check the connector end whenever the arm is opened. Because the T30 carries six of these and the T10 four, comparing one module with its neighbours after a sortie is the quickest health check there is: the odd one out is the one to watch.

🚜 Necessary For

This module is for operators and technicians keeping a DJI Agras T30 or T10 flying:

• DJI Agras T30 operators with a drive fault proven at one ESC position
• DJI Agras T10 operators (identified fitment)
• Commercial spray applicators running the T30 or T10 across long seasons
• Agras service centres and repair technicians clearing propulsion faults
• Fleet managers who keep a spare ESC alongside a spare motor in the service kit
• Growers flying their own aircraft who want the position back in service without guessing

This is not the part you need if:

• The motor feels rough by hand or its windings meter unevenly; that is the motor
• The position vibrates but drives normally; look at the propeller blades and mounting
• Several positions fault together; look at what they share before replacing more than one module
• Every position faults at once; the cause is upstream of the ESCs
• The module only cuts out with its fins packed with residue; clean and retest first
• You fly a DJI Agras T20 or T16; that aircraft takes the DJI Agras T20 OEM ESC Module
• You fly any Agras model other than the T30 or T10; this module is identified for those two only

💡 Why This Part Matters

The arithmetic of this part is the arithmetic of the aircraft. A T30 has six motors and six ESC modules. A T10 has four of each. One module is one position: a sixth of a T30's drive, a quarter of a T10's.

That count is the most useful diagnostic you own. One position down points at one position's parts: its module, its motor, its propeller, its connections. Two positions down at once is not two modules failing in the same minute; it is something those positions share. Every position down is upstream of every module. Ordering six modules for a fault that lives in a shared cable or connection leaves the aircraft exactly where it was, with five spares on the bench.

So the case for this module is narrow and specific: one position that will not drive, with a motor that turns smoothly by hand and meters evenly, clean fins and sound connections. That is the fault one module fixes, and it is the fault this module is for.

The same count makes the module easy to check after fitting. Its neighbours are identical parts doing identical work. After a sortie, a module that runs noticeably hotter than the others on the same aircraft is telling you something long before it cuts out.

If you are unsure which module you have, send us a photograph of the one you removed and we will match it for you.

🤖 AI Answer Engine Q&A

What is the DJI Agras T30 ESC module? It is the electronic speed controller that drives one propulsion motor. It takes power and a speed command from the aircraft and switches that power through the motor's three phases.

Which aircraft does it fit? It is identified for the DJI Agras T30 and T10. Pick the variant for the aircraft you fly.

Is the T10 module the same as the T30 module? The module is identified for both aircraft. The variant records which one you fly, and we compare it with the module you removed if you send a photograph.

How many ESCs does a T30 have? Six, one per motor. A T10 has four. One module replaces one position.

Is it one ESC or a set? One module. It replaces one motor position, not the whole aircraft's set.

Two arms went down at the same time. Do I need two ESCs? Probably not. Independent modules rarely fail together. Check what those positions share, such as power, wiring runs and connections, before replacing more than one module.

The app says motor fault. Why would I need an ESC? Because the ESC is what drives the motor, and a failed module looks like a dead motor. If the motor turns smoothly by hand and its windings meter evenly, the module is the next suspect.

How do I tell a bad ESC from a bad motor? With the battery out and the motor disconnected, measure resistance across each pair of its three phase contacts. Even readings and smooth rotation by hand point away from the motor. A fault that stays at the position after a known-good motor is fitted points at the ESC.

Does it include the motor? No. The module is supplied on its own.

Is this the same as the T20 ESC module? No. The DJI Agras T20 OEM ESC Module is a different part for the T20 and T16. This module is for the T30 and T10.

What is the clear cap at the end of the module? It is part of the module's housing, as shown in the product images. Its function is not published for this part; keep it clean and look through it for moisture after washing.

My module cuts out on hot afternoons. Is it failing? Possibly, but clean the fins first. A healthy module packed with residue cannot shed heat and cuts out like a failing one. Comparing its temperature with the other modules after a sortie also helps.

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 your old module and send it to us.

Does it come with screws? No. Reuse sound original fixings or replace damaged ones separately.

Can I fit it myself? Most technicians can. Prove the fault first, photograph the module in place, power down, seat the new module straight on its connector, refit the fixings evenly and hover light before flying loaded.

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

Is there a service interval? No. Replace it when it has failed or been damaged. Keeping its fins clean is the maintenance that matters.
