Abstract

The invention discloses a brushless motor. Motor comprising comprising a motor body, wherein thean installation plate which is connected with the motor body, and the a motor shell which is arranged onthe motor body in a sleeving mode and connected with the installation plate. A motor output shaft is arranged at one end of the motor body, a fixing plate is fixedly connected to the end, close to the motor output shaft, of the motor body through a bolt, a bolt hole matched with the bolt is formed in the fixing plate, the outer side of the fixing plate is fixedly sleeved with an installation piece, and the outer side of the installation piece is fixedly sleeved with an the installation plate. The installationmounting plate is of a rectangular plate-shaped structure, a clamping groove used formounting the motor shell is formed in the outer edge of the side, close to the motor body, of the mounting plate, one end of the motor shell is connected with the installationmounting plate in a clamped mode, the motor shell is of a rectangular structure, the installationmounting plate, the motor body and the motor shell are arranged in a right-angle structure, and a base is arranged below the motor shell. The brushless motor is reasonable in design, is and convenient to use, and is good in heat dissipation effect.

Description

technical field [0001] The invention belongs to the technical field of brushless motors, and in particular relates to a brushless motor. Background technique [0002] The brushless motor consists of a motor body and a driver, and is a typical mechatronic product. Since the brushless DC motor operates in a self-controlled manner, it does not add an additional starting winding to the rotor like a synchronous motor with heavy load under variable frequency speed regulation, nor does it cause oscillation and out of step when the load changes suddenly. [0003] The brushless motor will generate heat when it is working, and the traditional brushless motor housing does not have the function of heat dissipation. If the brushless motor cannot be cooled in time, the internal parts of the brushless motor may be damaged due to excessive temperature. Damage, thereby reducing the service life of the brushless motor, the support device of the existing brushless motor is not easy to adjust,...
