摘要： A motor includes a mounting bracket; a stator mounted to one of opposite sides of the mounting bracket; a rotor is rotatably supported on the stator; and a control unit the other of the opposite sides of the mounting bracket away from the stator. The control unit includes a plate-shaped heat dissipating member fixed to the mounting to the mounting bracket, and a circuit board attached to a side of the heat dissipating member away from the mounting bracket. A seal is formed between a periphery of the heat dissipating member and the mounting bracket.

摘要： A rotatory device (1) for energy conversion between electrical energy and mechanical energy includes an end cap (20) to which electric conduction and commutation components (30) are attached. The end cap (20) is electrically insulating and has a flange mating to an electric conductive housing (10) of the rotatory device (1). An unpackaged capacitor (40) is positioned between the housing (10) and the flange (20) without occupying other space inside the housing (10) of rotatory device (1). The unpackaged capacitor (40) is electrically coupled to the electric conduction and commutation component and grounded to the housing (10) of the rotatory device (1).

摘要： A magnetic core of an electric motor includes a central portion and a plurality of teeth extending outwardly from the central portion, the teeth disposed along a circumferential direction of the central portion. Each tooth includes a tooth body, two neck portions and two crown portions, the neck portions respectively connecting the crown portions to the tooth body, the two crown portions respectively extending beyond opposite sides of the tooth body. Each of the two neck portions of each tooth has a minimum width which is 0.1˜0.3 times of the width of the tooth body. The present invention further provides an electric motor that employs the magnetic core which can increase the peak value of the cogging torque of the motor.
