4006 Stator — 39mm OD × 15.5mm ID × 18 Slots × 0.35mm Silicon Steel
The 4006 stator is a 39mm OD × 15.5mm ID × 18-slot laminated core built with 0.35mm silicon steel, engineered for 40-series brushless drone motors that require a strong balance of torque, efficiency, and thermal stability.
As a proven 4006 motor stator, it is widely used in 4006 and 4010 motor projects across FPV drones, fixed-wing UAVs, and long-shaft drone motor builds. The 18-slot configuration paired with 0.35mm silicon steel helps deliver reliable magnetic performance and stable power output under sustained high-load conditions.
Lamination & Stamping — 4006 Motor Stator
This 4006 motor stator lamination is manufactured from 0.35mm silicon steel with a precise 39mm outer diameter, specifically engineered for 40-series brushless drone motors.
The stator height is fully customizable to meet your application requirements. Below are typical height configurations widely used in the drone industry:
Whether you need a compact 4006 stator for FPV applications or a longer-stack 4010 motor stator for fixed-wing and high-thrust drone motors, this 39mm OD platform provides a versatile and reliable foundation.
H-Class 180℃ Epoxy Coating — 4006 Stator
All 4006 stator laminations are coated using H-Class 180℃ electrostatic epoxy powder coating technology, which is especially well-suited for low-voltage motors in drone and UAV applications.
The electrostatic process ensures:
Uniform surface coverage across the entire lamination
Reliable insulation performance — helps prevent short circuits during winding
Enhanced corrosion resistance — extends stator lifespan in demanding environments
Improved protection during winding and motor assembly
To guarantee consistent quality, we apply 100% Hi-Pot testing on every 4006 motor stator before shipment, ensuring full compliance with insulation performance standards.
Custom Winding Services — 4010 Motor Stator
We offer fully custom winding services to match your motor design specifications.
Our standard KV option for the 40 series is KV390, and we also accept custom winding with any KV value according to your specific performance requirements.
With ready-made winding fixtures, we help motor builders and manufacturers move from 4006 stator core selection to complete motor production more efficiently — whether you are developing a 4006 motor stator for FPV or a 4010 motor stator for fixed-wing applications.
100% Quality Inspection
Every 4006 stator, 4006 motor stator, and 4010 motor stator undergoes 100% electrical performance testing before delivery:
Hi-Pot Testing — verifies insulation integrity
3-Phase Resistance Testing — ensures winding consistency and phase balance
Surge Waveform Testing — detects turn-to-turn short circuits
These quality steps help ensure that every stator meets the reliability requirements of drone motor applications.
