Description

Technical Field

[0001] The utility model relates to the technical field of brushless motors, in particular to a high-voltage isolated brushless motor controller. Background Art

[0002] The brushless DC motor consists of a motor body and a driver. It is a typical mechatronics product. The brushless DC motor operates in an automatic control mode, so it does not have an additional starting winding on the rotor like a synchronous motor that starts under heavy load under variable frequency speed regulation. It will not produce oscillation and loss of step when the load changes suddenly. The brushless motor will generate high voltage when working and thus damage the control, so a high-voltage isolated brushless motor controller is required.

[0003] When operators perform high-voltage isolation work on brushless motor controllers, they often use corresponding high-voltage isolated brushless motor controllers. Although existing controllers can achieve the purpose of high-voltage isolation, the controllers will generate a lot of heat during actual use. Fins are mostly used for heat dissipation, but dust will accumulate during long-term use, which may affect the heat dissipation effect of the controller. In addition, the fixing method of the control unit is single, which may cause looseness during long-term use, thereby affecting the normal use of the controller. Utility Model Content
