High Voltage Permanent Magnet Electric Motor

Last update: 04 Sep. 2023

What is a high-efficiency permanent magnet motor?

The high-efficiency Permanent Magnet Electric Motor is a reversible machine: during acceleration, the machine converts the electric energy into the rotating mechanical energy required to propel the vehicle and during deceleration, the machine regenerates energy, meaning the machine converts back mechanical energy into electric energy.

This electric motor is a Permanent Magnet Synchronous Motor (PMSM). Valeo’s core technology is using permanent magnets in the rotor and hairpin winding in the stator in order to reach the best trade-off between efficiency, performance, weight and cost. This motor technology is suitable for a primary traction motor or an auxiliary boost motor.
