Traction Motor: Notes

WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.

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.

TRACTION MOTOR RESOLVER

The traction motor resolver is located coaxially with the traction motor, and detects the rotor rotation angle. The rotation angle is sent to the motor controller.

CAUTION: If the traction motor inverter or traction motor was replaced, be sure to perform writing of the traction motor resolver offset. Refer to "DESCRIPTION ".
