Parking Actuator

COMPONENT PARTS

Parking Actuator

- The parking actuator is installed above the reduction gear.
- The parking actuator is operated by the signal from the electric shift control module and locks/unlocks the parking mechanism in the reducer.
- The parking actuator consists of the motor, encoder, angle sensor, and actuator reduction gear.






MOTOR

- A dual 3-phase SR motor is used.
- Two different types of coils are placed on the stator core around the motor and the current that passes through the coils in sequence generates the rotating force for the inner rotor core.






ENCODER

- The Hall IC type rotation angle sensor is used for higher accuracy in the detection of the rotor rotation angle.
- It detects the rotor rotation angle and outputs pulse signals to the electric shift control module.
- The electric shift control module controls the timing of the current feed to the coils optimally based on the signal from the encoder.

ANGLE SENSOR

The Hall IC type angle sensor is used for higher accuracy in the detection of the manual plate angle.

ACTUATOR REDUCTION GEAR

The actuator reduction gear consists of a cycloidal gear and includes a motor with its torque amplified for secure operation under high torque-requiring conditions.
