Traction Motor: Notes

The traction motor contains an "Interior Permanent Magnet Synchronous Motor (IPMSM)". A permanent magnet is embedded inside the rotor core, and the rotating magnetic field generated by the stator coil is used to generate rotational torque.
The traction motor is able to generate torque even when the vehicle is stopped, and outputs maximum drive torque when the vehicle starts moving in order to provide good initial acceleration.
