Abstract

An actuator includes a controller, a motor and a sensor device. The controller includes a housing, and the motor includes a rotor, and the rotor includes a rotating shaft. The motor is mounted on the outside of the housing, and the sensor device includes a magnet and a sensor, the magnet is mounted on the rotating shaft of the motor, and the sensor is mounted inside the housing. The actuator has a good waterproof performance and anti-interference ability. This disclosure also relates to an electronic clutch system having the actuator.

Claims (19)

1. An actuator, comprising:

a controller comprising a housing;

a motor comprising a rotor, and the rotor comprises a rotating shaft; and

a sensor device;

wherein the motor is mounted on the outside of the housing, and the sensor device comprises a magnet and a sensor, the magnet is mounted on the rotating shaft of the motor, and the sensor is mounted inside the housing; wherein a groove is disposed on one side of the housing, one end of the rotating shaft is received in the groove, and the magnet is mounted on the end of the rotating shaft; wherein the sensor device further comprises a mounting member secured to the end of the rotating shaft, and the magnet is mounted in the mounting member, facing a bottom wall of the groove; wherein the mounting member comprises a latching portion for latching on the rotating shaft and a receiving portion for receiving the magnet, one end of the latching portion is provided with a clamping groove, and one end of the rotating shaft is retained in the clamping groove.

2. The actuator of claim 1 , wherein a receiving cavity is formed in the housing, the sensor is disposed in the receiving cavity.
