Abstract: An actuator includes a motor driving a worm, a gearbox, and a motor control module. The gearbox includes a gearbox housing, a worm wheel for meshing with the worm, an output mechanism fixed to the worm wheel. The gearbox housing defines worm chamber and worm wheel chamber. The motor control module includes a control module housing, a printed circuit board and a connector of the printed circuit board. The control module housing defines a control module chamber and the connector is mounted at an open end of the control module chamber. The control module housing is connected with the gearbox housing. The control module chamber and the worm wheel chamber are located on opposite sides of the worm chamber. An isolation slot is defined between the control module chamber and the worm chamber.
