Abstract

The invention relates to the technical field of motor equipment, and specifically relates to a brushless direct-current motor. The motor comprises a direct-current brushless motor, an extension shaftcomponent, a connecting sleeve component, a lifting insertion column limiting component, a limiting sleeve component, a gear main body component, a limiting extrusion device, an end sleeve bearing component and an extrusion fixing device. The brushless direct-current motor is fixedly connected with an extension shaft component. The brushless direct-current motor is rotationally connected with a connecting sleeve component. Two lifting insertion column limiting components are fixedly connected to the connecting sleeve component. The two lifting inserting column limiting components are both connected with the direct-current brushless motor in a sliding mode. The connecting sleeve component is rotatably connected with a limiting sleeve component, the extension shaft component is slidably connected with a gear main body component, the limiting extrusion device is rotatably connected with the extension shaft component and makes contact with the gear main body component, and the device can be conveniently connected with a gear and a shaft and has the advantage of being rapid to connect and use.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a DC brushless motor. Background technique [0002] The brushless DC 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, 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 generation of brushless motors. However,...
