Abstract

The invention relates to a direct current brushless motor which is provided with a brake and used for clutch. The direct current brushless motor is characterized in that a front end cover assembly (2) is fixed at the left end of a stator assembly (3), an end cover assembly (5) is fixed at the right end of the stator assembly (3), a sensor assembly (6) is mounted on the end cover assembly (5), a sensor protective cover (7) is fixed on the end cover assembly (5) and used for covering the sensor assembly (6); the left end of the rotor assembly (4) is connected with a bearing (9) on the front end cover assembly (2), and the right end of the rotor assembly (4) is connected with a bearing (9) on the end cover assembly (5) and is limited by a clamping spring II (10) arranged on the rotor assembly (4); and an electromagnetic brake (1) is fixed on the front end cover assembly (2), and a positioning block (11) in fit with the electromagnetic brake (1) is arranged on the rotor assembly (4). The direct current brushless motor provided by the invention has the advantages that a mechanism is locked when the motor does not work and stable rotational position of the motor is guaranteed.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a DC brushless motor for a clutch with a brake. Background technique [0002] The existing ATM clutch actuator uses a brushless DC motor without an electromagnetic brake. The motor cannot lock the mechanism when it is not working, and rebound phenomenon will occur, which will affect the positioning accuracy of the controller. Contents of the invention [0003] In view of the above disadvantages, the object of the present invention is to provide a DC brushless motor with a brake, which has the advantages of locking the mechanism when the motor is not working, and ensuring the stability of the motor's rotational position. [0004] The technical solution of the present invention is realized in the following manner: a DC brushless motor for a clutch with a brake, which consists of an electromagnetic brake, a front end cover assembly, a stator assembly, a rotor assembly, an end cover...
