ROTOR COMPONENT

id301000200500

Purpose, Function

During driving

• The rotating magnetic field generated by the stator coil causes the permanent magnet of the rotor coils to attract/repel, which rotates the rotor component.

• The rotating rotor component transmits the power to the EV transaxle to rotate the drive wheels.

During regenerative braking

• The drive force from the drive wheels is transmitted to the EV transaxle and rotates the rotor component.

• The permanent magnet in the rotor component generates electrical power in the stator coil by changing the magnetic flux around the stator coils.

Construction

• The rotor component consists of the rotor core, magnets, rotor shaft, and other parts.

Operation

• The rotation direction of the motor is changed by changing the direction of the rotating magnetic field in the stator coil.

• When the driver performs shift operation, the shift position information is input from the electric shift lever component to the PCM.

• The PCM determines the normal/reverse rotation of the motor based on the input shift position information. (See DRIVE FORCE CONTROL.)

• The PCM sends the normal/reverse rotation command to the inverter.

• The inverter switches the electrical power input to the stator coils to perform normal/reverse rotation of the motor.
