Description
Motor position sensor
Accurate motor rotor absolute position detection is required for motor control.The MCU can control the motor under optimal conditions using the position and speed of the rotor transmitted from the resolver. The resolver is mounted on a rear plate and consists of the rotor connected with motor rotor, and stator connected with housing. This locates the position of the rotor inside the motor, like the CMP sensor of the ICE vehicle.Motor temperature sensor
The motor temperature sensor is assembled on the motor coil and is responsible for sensing motor temperature information for torque compensation and motor over-temperature protection according to temperature.Component and Component Location

Removal
• When working on high voltage system, the work should be performed by technicians who have completed the relevant training. It is because that lack of knowledge of the high voltage system can lead to serious accidents due to electric shock or electric leakage.
• When working a high voltage system, the technician must be recognized and observe "General Safety Information and Caution". If do not follow, serious accidents like electric shock and short circuit are caused.
• When working on high voltage system, make sure to check the Personal Protective Equipment (PPE) and high voltage shut-off procedures.
• Use a fender cover to protect the painted surface.
• Be careful not to damage the connector when disconnecting.
