When the traction motor inverter receives the target motor torque signal from the VCM via EV system CAN.

TRACTION MOTOR INVERTER SIGNAL STATUS

(4) <= (3) <= (2) <= (1)
The drive torque from the traction motor is output as kinetic energy.   The AC power from the traction motor inverter is converted to magnetic energy and a rotating magnetic field is created in order to generate drive torque.   The traction motor inverter (IGBT) switches in order to convert the DC power from the Li-ion battery to AC power.   The DC power from the Li-ion battery is input to the traction motor inverter.
