Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
IMA Motor
The IMA motor is a synchronous AC type unit that converts electrical energy into kinetic energy and vice versa. It assists the engine during acceleration, runs the vehicle during low speed cruise, and starts the engine.
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.
