Abstract

The invention belongs to the technical field of DC brushless motors, and particularly relates to a voice control DC brushless motor. The DC brushless motor comprises a DC brushless motor body and a Bluetooth trigger unit. A vacuum box is arranged outside the DC brushless motor body, wherein the input end of the DC brushless motor body is fixedly connected with the end part of the vacuum box, and the output end of the DC brushless motor body comes out of the vacuum box. The Bluetooth trigger unit is used for controlling the DC brushless motor body, and a server is arranged on the DC brushless motor body. The DC brushless motor body is electrically connected with the server. By using the Bluetooth trigger unit and the vacuum box, the DC brushless motor body is controlled in a voice control mode, thereby effectively improving the working accuracy of the sound control DC brushless motor body.

Description

technical field [0001] The invention belongs to the technical field of DC brushless motors, in particular to a sound-activated DC brushless motor. Background technique [0002] The DC brushless motor consists of a motor body and a driver, and is a typical mechatronic product. A brushless motor refers to a motor without a brush and a commutator (or slip ring), also known as a commutator-less motor. As early as the 19th century, when the motor was born, the practical motor produced was a brushless form, that is, an AC squirrel-cage asynchronous motor, which was widely used. However, asynchronous motors have many insurmountable defects, so that the development of motor technology is slow. Transistors were born in the middle of the last century, so brushless DC motors that use transistor commutation circuits instead of brushes and commutators came into being. This new brushless motor, called an electronically commutated DC motor, overcomes the shortcomings of the first genera...
