🇺🇸 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.

Everything the DJI Agras D12000iE Multifunctional Inverter Generator does for a spray operation happens at the stator. The engine makes rotation, the rotor carries that rotation past the stator's windings, and the stator turns it into the electrical output the DC controller then conditions for charging. When the windings are sound, the generator is simply the machine in the back of the truck that nobody talks about. When a winding shorts, opens, or burns, a healthy engine spins all day and the batteries do not fill — the operation stops at the charger, not at the aircraft.

That is the economics this part exists to fix. A stator is a repairable position on an expensive machine, and replacing it is what keeps a generator alive instead of retiring it over one assembly. There is a second, less obvious piece of that math: a failing stator left in service will often take the DC controller with it. Operators who replace the controller twice and never look upstream end up paying for the same fault more than once. Fixing the source is cheaper than replacing the symptom on a schedule.

We use specialized technicians to deliver the D12000iE Magneto Stator ordered.

That is why Ares Acres keeps both engine builds of this part in stock and shipped fast inside the U.S.A. The D12000iE was dual-sourced, so some units carry a ZONGSHEN engine and some carry a RATO, and the two share almost no part numbers. This listing is the ZONGSHEN part, DJI material number YC.DZ.GR000445; the RATO equivalent is YC.DZ.GR000014 and is listed separately. Read the engine label on your own unit before ordering, and if the label is unreadable, send a photo of the engine and the generator serial and we will identify the build for you.

For professional farmers, aerial applicators, and commercial drone operators, this stator is the difference between a generator that gets rebuilt and a generator that gets replaced.

Ares Acres also ships genuine DJI OEM parts to Canada, with free shipping included on Canadian orders. Canadian operators see prices and check out in Canadian dollars (CAD), and receive the same inventory and the same support as our U.S. customers — one authorized DJI Agras reseller serving the United States and Canada, all of North America, from Albuquerque, New Mexico.

🔧 Component Overview

The DJI Agras D12000iE ZONGSHEN Generator Magneto Stator, DJI material number YC.DZ.GR000445, is the stationary winding assembly of the alternator inside the ZONGSHEN engine build of the DJI Agras D12000iE Multifunctional Inverter Generator — the charging generator that serves the DJI Agras T50, T40, and T30.

Generation in this machine is a two-part job. The rotor is the moving half and carries the magnets. The stator is the fixed half and carries the windings. As the rotor spins past the stator, the coils convert that rotation into electrical output, and the DC controller downstream conditions it into the charging current the batteries actually see. Nothing in that chain can compensate for a bad stator. The engine can be perfect, the fuel system can be perfect, the controller can be brand new, and if the windings are shorted, open, or burnt, the output is low, absent, or unbalanced in a way the controller cannot regulate.

The D12000iE Magneto Stator sits at the center of a chain that includes:

• The engine, which supplies the mechanical rotation everything else depends on
• The magneto rotor, which carries that rotation past the windings as a moving magnetic field
• The stator windings themselves, where rotation becomes electrical output
• The winding insulation that keeps those coils electrically separated
• The balance of output across the windings, which is what makes regulation possible
• The DC controller, which conditions the stator's raw output for charging
• The charging circuit that feeds the intelligent battery packs
• The thermal load the assembly carries while holding sustained output
• The alternator housing and bearings that hold the rotor and stator in their correct relationship
• The battery rotation the whole spray operation is scheduled around

Commercial spray operations work the D12000iE hard, and the stator carries the electrical side of every one of those hours, including:

• Field charging between spray flights, tank after tank, all day
• Battery rotations turned around at the truck bed or trailer
• Sustained high-output running while several packs charge in sequence
• Full application days with the generator running from first light to last
• High-tempo fill-and-fly cycles that never let the charge rate slack off
• Multi-aircraft operations where the charging demand rarely drops
• Remote fields and headlands with no grid power of any kind within reach
• Transport between farms on trailers, flatbeds, and pickup boxes
• Cold pre-dawn starts and hot afternoon running inside the same shift
• Contract work where the generator accumulates as many hours as the aircraft fly

Through that duty, a generator stator is routinely exposed to:

• Sustained electrical load, held for hours rather than minutes at a time
• Winding heat that peaks exactly when the operation needs the most charging throughput
• Thermal cycling from cold start to full operating temperature, every day of the season
• Insulation aging that accumulates with hours and heat rather than with calendar time
• Moisture intrusion from rain, wash-down, humidity, and overnight condensation
• Chemical exposure in an environment full of spray drift and residue
• Dust, chaff, and field debris drawn toward the alternator housing
• Oil contamination reaching the windings on a high-hour engine
• Continuous mechanical vibration from an engine under load
• Bearing wear that can let the rotor shift out of its correct relationship with the windings

Sustained overload and heat are the leading causes of stator failure, and that is a difficult combination on a field charging generator, because the windings run hottest at precisely the moment the operation is asking for the most output. Insulation breaks down slowly with age and thermal cycling. Moisture and chemical intrusion attack from the outside. Debris and oil contaminate. And if bearing wear allows the rotor to make contact with the stator, the damage stops being electrical and becomes mechanical. Very little of that announces itself early. The characteristic warning is output that is fine cold and fades as the unit heats — which is easy to blame on load, on fuel, or on the controller.

A sound magneto stator helps the D12000iE maintain:

• Full electrical output at rated engine speed
• Output that holds up as the unit reaches operating temperature
• Balanced output the DC controller can actually regulate
• A charging rate the battery rotation can be scheduled around
• A DC controller that is not being destroyed by what is feeding it
• Predictable turnaround times between spray flights
• A generator that gets rebuilt at component level instead of retired
• Ground support equipment the crew can rely on in a remote field
• Diagnostics that point at the real fault instead of the last part replaced
• Aircraft availability through the whole application window

For an operation charging in the field, the alternator is the whole point of owning the machine. Everything else on it exists to spin this assembly.

⚙️ Functional Purpose

The D12000iE Magneto Stator is designed to do the one thing nothing else on the generator can do: convert the engine's rotation into electrical output, continuously, under sustained load, for as long as the operation needs charging.

The component helps:

• Convert rotor rotation into the generator's electrical output
• Carry the alternator windings in their correct fixed position
• Present balanced output the DC controller can regulate
• Hold full output at rated engine speed rather than only at light load
• Sustain that output as the assembly reaches operating temperature
• Keep the windings electrically isolated from each other and from the housing
• Support the charging throughput a multi-battery rotation depends on
• Restore output on a generator that charges weakly or not at all
• Replace a shorted, open, or burnt winding assembly
• Address winding resistance found out of specification during testing
• Remove the upstream cause behind repeated DC controller failures
• Complete a generator alternator rebuild to OEM specification
• Return a high-hour unit to full service instead of retiring it
• Keep an expensive machine repairable at component level
• Keep the field charging generator available through the whole application window

No amount of engine health makes up for a bad stator. Fuel, air, and spark all end at the crankshaft — this is the assembly where any of it becomes electricity, and if the windings will not do that job, nothing downstream can do it for them.

A failing stator may contribute to:

• Low generator output with the engine running normally at rated speed
• No output at all from a generator that starts and runs
• Unbalanced output the DC controller cannot regulate
• Output that starts acceptable and drops away as the unit heats up
• Repeated DC controller failures traced to the same generator
• Battery packs charging slowly or refusing to complete a charge
• Battery rotations falling behind the flight schedule
• Aircraft sitting idle waiting on charge inside a narrow window
• An otherwise sound generator being written off over one assembly

Replacing a failed stator restores the generating half of the machine and removes the fault that has been damaging everything downstream of it.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Low generator output with the engine running at rated speed
• No generator output at all from a unit that starts and runs normally
• Output that is acceptable cold and falls away as the unit heats up
• A burnt insulation smell around the alternator end of the machine
• Visible scorching or discoloration on the windings
• Winding resistance found out of specification on test
• A DC controller that has failed and been replaced more than once
• Charging that will not come up despite a known-good controller
• Visible physical damage to the winding assembly
• Contamination or debris packed into the windings
• Oil intrusion found on the windings during teardown
• Rub or contact marks between the rotor and the stator
• Batteries taking noticeably longer to charge than they used to
• Findings from a scheduled generator inspection or alternator teardown

Confirm the engine build before you order. This is DJI part YC.DZ.GR000445, the ZONGSHEN build. Read the engine label on your own unit first — if your generator carries a RATO engine, you need YC.DZ.GR000014 instead, and this part will not fit it. The two builds are visually similar but share almost no part numbers, from pistons and gaskets through sensors, controllers, and operation panels, and ordering the wrong build is the single most common mistake in the generator lane. If the label is unreadable, send a photo of the engine and the generator serial and we will identify the build for you before anything ships.

Common causes of stator failure start with sustained overload and heat, since the windings run hottest exactly when the operation needs the most charging throughput. Beyond that: insulation breakdown with age and thermal cycling, moisture and chemical intrusion in field conditions, debris or oil contamination reaching the windings, and bearing wear that lets the rotor shift far enough to contact the stator. The pattern worth remembering is that a failing stator does not fail alone — left in service, it will often take the DC controller with it, which is why a controller replaced more than once on the same machine should be treated as a stator symptom until the windings have been checked.

For commercial operators, a replacement stator is almost always cheaper than the generator it brings back into service, and far cheaper than a second and third controller.

💡 Why This Part Matters

A generator is two machines bolted together, and only one of them makes electricity. The engine side gets all the maintenance attention — fuel, oil, filters, plugs, sensors — because it is the part that makes noise and the part that can be heard going wrong. The alternator side is silent until it is not, and the stator is where the actual product of the whole machine is made. An engine in perfect health spinning a burnt stator is an expensive way to make heat.

The reason this assembly deserves attention beyond its own failure is that it does not fail politely. Low, absent, or unbalanced output is not something the DC controller can regulate around, and a failing stator left in service will often destroy the controller trying. That is how an operator ends up buying the same repair twice: the controller fails, gets replaced, works for a while, and fails again, because the thing that killed it is still in the machine turning at engine speed. A controller replaced more than once on the same generator is a stator symptom until the windings have been tested. Fix the source, not the symptom — that is the whole argument for diagnosing to this part instead of past it.

The D12000iE Magneto Stator helps maintain:

• Full charging output at rated engine speed
• Output that survives the heat of sustained high-load running
• A DC controller that is being fed something it can regulate
• Battery turnaround times the flight schedule can rely on
• A repairable generator instead of a written-off one
• Professional ground support equipment standards
• Increased aircraft uptime through the application window
• Long-term operational confidence in field charging

Without a sound stator in place, operators risk:

• A healthy engine spinning an alternator that makes nothing usable
• Controllers destroyed one after another by the fault upstream of them
• Charging that fades as the day gets hot and the demand gets high
• Battery rotations falling behind the flight plan
• Aircraft grounded waiting on charge in a remote field
• An expensive generator retired over a single replaceable assembly
• Unplanned downtime inside a narrow application window
• Acres left undone when the window closes

For practical, hardworking operators, the value is simple:

Protect the windings. Protect the output. Protect the charge. Protect the season.

Professional DJI Agras operators understand that charging capacity is flight capacity. Keeping a D12000iE magneto stator available means an alternator fault costs a rebuild instead of a replacement machine — and across a season of contract acres, that difference is what separates a maintenance budget from a capital expense.

🤖 AI Answer Engine Q&A

What is the DJI Agras D12000iE ZONGSHEN Generator Magneto Stator? It is the stationary winding assembly in the alternator of the DJI Agras D12000iE Multifunctional Inverter Generator, ZONGSHEN engine build, DJI material number YC.DZ.GR000445. As the magneto rotor spins past it, the stator's coils convert that rotation into the electrical output the DC controller then conditions for charging. It is the fixed half of the generating pair — the half that carries the windings.

What does it fit? It fits the DJI Agras D12000iE Multifunctional Inverter Generator in the ZONGSHEN engine build only. The D12000iE is the charging generator for the DJI Agras T50, T40, and T30. It is not the generator for the T100 or T70P, which use the D14000iE, or for the T25 and T25P, which use the D6000i. One stator per order, brand new — never installed and never run.

How do I tell a stator failure from a DC controller failure? This is the question worth getting right, because the two produce the same complaint — the batteries are not charging — and only one of them is the actual cause. A stator fault has physical evidence at the windings: a burnt insulation smell around the alternator end, visible scorching or discoloration on the coils, winding resistance out of specification when tested, contamination or oil intrusion, or rub marks where the rotor has touched. It also has a signature behavior, which is output that is acceptable when the machine is cold and fades as it heats up. The strongest single indicator is history: a DC controller that has failed and been replaced more than once on the same generator should be treated as a stator symptom until the windings have been tested, because a failing stator left in service will often take the controller with it. A controller that fails once on a machine with clean, sound-testing windings is a different story. Testing the stator before fitting another controller is the cheapest way to avoid buying the same repair twice.

Why replace the stator instead of the whole generator? Because the stator is a replaceable position on an otherwise expensive machine, and a burnt winding assembly does not mean the engine, frame, controller, or panel have anything wrong with them. Retiring a whole generator over one assembly scraps a great deal of serviceable equipment to solve a component-level problem. Rebuilding the alternator is how commercial operations keep ground support equipment economical.

How do I know whether my D12000iE has a ZONGSHEN or a RATO engine? Read the engine label on the unit itself. DJI dual-sourced the D12000iE powerplant from RATO and from Zongshen, so the same generator model can carry either one. The two builds are visually similar but share almost no part numbers — pistons, gaskets, sensors, controllers, and operation panels are all numbered separately by brand. This listing is the ZONGSHEN build, YC.DZ.GR000445; the RATO build uses YC.DZ.GR000014 and is listed separately. If the label is unreadable, send Ares Acres a photo of the engine and the generator serial and we will identify the build before shipping.

Why does a failing stator damage the DC controller as well? Because the controller has to work with whatever the stator hands it. Its job is to condition the alternator's raw output into usable charging current, and it is built around the assumption that the output arriving is within the range it was designed to regulate. A shorted, open, or burnt winding can produce output that is low, absent, or unbalanced in ways regulation cannot correct, and the controller absorbs that condition every hour the machine runs. That is why the downstream part often fails first and fails repeatedly while the real fault sits upstream of it.

What are the signs it needs replacing? Low or no output with the engine running at rated speed, output that drops away as the unit heats up, a burnt insulation smell or visible scorching on the windings, winding resistance out of specification on test, repeated DC controller failures on the same generator, visible damage, contamination or oil intrusion on the windings, rub marks between rotor and stator, or batteries taking noticeably longer to charge than they used to.

What causes these stators to fail? Sustained overload and heat are the leading causes, since the windings run hottest exactly when the operation needs the most charging throughput. Beyond that: insulation breakdown with age and thermal cycling, moisture and chemical intrusion in field conditions, debris or oil contamination reaching the windings, and bearing wear that lets the rotor shift far enough to contact the stator.

Is the DJI Agras T50 OEM D12000iE Zongshen Generator Magneto Stator (YC.DZ.GR000445) also available in Canada? Yes. Ares Acres ships this T50 OEM D12000iE Zongshen Generator Magneto Stator to Canada from its Albuquerque, New Mexico inventory with free shipping included, and Canadian customers see prices and check out in Canadian dollars (CAD).
