85mm Distributed Winding Stator and Rotor– Product Overview

The 85mm distributed winding stator and rotor set is designed for electric compressor and pump motors requiring stable electromagnetic performance and smooth torque output.
Compared with concentrated winding structures, the distributed winding layout helps reduce torque ripple and harmonic distortion, making it suitable for applications where low vibration and acoustic performance are critical.

This stator–rotor platform supports typical automotive voltage systems such as 320V and 400V, and is optimized for long duty cycles in sealed or semi-sealed motor assemblies.
