Description

Brushless motor mount pad

Technical Field

Background

The brushless direct current motor is composed of a motor main body and a driver, and is a typical electromechanical integration product. Because the brushless DC motor is operated in a self-control mode, a starting winding is not additionally arranged on a rotor like a synchronous motor which is started under the condition of heavy load under the condition of frequency conversion and speed regulation, and oscillation and step-out can not be generated when the load suddenly changes. The permanent magnet of the brushless DC motor with medium and small capacity is mostly made of rare earth neodymium iron boron (Nd-Fe-B) material with high magnetic energy level. Therefore, the volume of the rare earth permanent magnet brushless motor is reduced by one machine seat number compared with that of a same-capacity three-phase asynchronous motor. In the process of using the brushless motor, the brushless motor can be normally used only by fixing, so that the mounting seat can be used, but the traditional mounting seat is too simple and cannot protect the working brushless motor.
