Description
technical field [0001] The invention relates to the field of brushless motors, in particular to a noise-reducing high-power permanent magnet brushless motor. Background technique [0002] New energy vehicles have three major advantages: environmental protection, saving and simplicity. It is especially evident in pure electric vehicles: an electric motor is used instead of a fuel engine, driven by an electric motor without an automatic transmission. Compared with the automatic transmission, the motor has simple structure, mature technology and reliable operation. As one of the core components of new energy vehicles, brushless motors and their control systems have promising prospects for future development. [0003] The existing permanent magnet brushless motors still have certain defects in use. The assembly of the existing brushless motors is slow, and the rotor core is also prone to warping, and the electromagnetic block is easy to dislodge from the rotor core during oper...
