Abstract

The invention provides a brushless DC motor, comprising a stator, a rotor, a circuit board and a shell cover; wherein the stator comprises a stator iron core, a plurality of stator windings and insulators; the rotor is arranged in the stator; the circuit board is used for providing power drive and control for the brushless DC motor; the shell cover is used for containing the stator, the rotor and the circuit board; the stator also comprises an insulating member which is arranged in the shell cover and connected with the shell cover in a de-mountable mode, and the stator iron core and the insulators are arranged on the first side surface of the insulating member, and the circuit board is arranged on the second side surface of the insulating member. The inner components of the brushless DC motor are reliably connected with simple structure and good insulation and sealing functions.

Description

【Technical field】 [0001] The invention relates to a brushless direct current motor, in particular to a brushless direct current motor in which internal components of the motor are reliably installed on its shell cover through an insulating member. 【Background technique】 [0002] Home appliances, such as compressors in refrigeration systems, washing machines, electric fans, etc., are usually powered by motors. General brushed motors usually switch the current input to the coil through the mechanical means of commutators and brushes. The speed of this brushed motor is relatively easy to control, but the mechanical running-in of brushes and commutators often accelerates the loss of the motor, and prone to noise. Brushless DC motor is a DC motor that uses electronic rectifiers instead of brushes and commutators. It has a series of advantages such as simple structure, reliable operation, and convenient maintenance of AC motors. It has many characteristics such as good loss and ...
