Traction Motor Inverter: 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.

NOTE: Control of the traction motor and control of EV system CAN communications with other control modules is actually performed by the motor controller. However because the motor controller is installed inside the traction motor inverter, the motor controller is here referred to as the traction motor inverter.

The traction motor inverter is composed of the motor controller, driver, smoothing condenser, 3 current sensors, and power module.
The traction motor inverter controls the traction motor based on the target motor torque signal transmitted by EV system CAN from the VCM.
Traction motor inverter drives traction motor accurately based on resolver detection signal and current sensor detection signal.
The traction motor inverter performs charging judgment for the high voltage circuit and also discharges the voltage inside the circuit.
The traction motor inverter performs vibration control in order to improve accelerator response and provide good acceleration while driving.
