IMA Motor

The IMA motor assists the engine during acceleration, runs the vehicle during low speed cruise, starts the engine, and charges the battery module.

The IMA motor is located between the engine and the transmission. It consists of a 3-phase coil stator and a permanent magnet rotor that is directly connected to the engine crankshaft. An IMA motor rotor position sensor is mounted on the back of the engine block to detect the position of the rotor.
