Abstract

A brushless direct-current motor of a water pump comprises a brushless motor body and a controller. The brushless motor body comprises a front end cover, a back end cover, a stator and a Hall sensingdevice, wherein the stator is mounted between the front end cover and the back end cover and is connected with a three-phase input line, and the Hall sensing device is mounted on the stator and is connected with a Hall signal terminal. The controller is positioned in the brushless motor body, fixed on the back end cover and electrically connected with the three-phase input line. The Hall sensing device is electrically connected with a Hall detection device through the Hall signal terminal and inputs a Hall signal into the Hall detection device for detection. A MCU master control device is usedfor processing a signal detected by the Hall detection device and controlling a drive device to drive the brushless motor body to run and stop. The brushless direct-current motor of the water pump has the advantages that the brushless direct-current motor with the built-in controller avoids space occupancy of an external controller, thereby being more compact in system structure and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to a water pump DC brushless motor. Background technique [0002] With the development of society, people's living standards are improving day by day, and the requirements for efficient use of energy and environmental protection are getting higher and higher. The country also encourages the development of new energy vehicles. New energy buses are public transportation vehicles. The water cooling system of new energy buses is the key to ensure the long-term stable operation of the vehicle. Therefore, the cooling water pump has high requirements and must maintain long-term stable operation. The water pump is required to be small in size and long in life. Long, strong water absorption. Permanent magnet brushless DC motor is a new type of electromechanical motor that has emerged with the development of modern electronic technology-level new materials. It has the a...
