Abstract

The invention discloses a permanent magnet synchronous motor. The permanent magnet synchronous motor comprises a stator core (20) and a stator winding (30) capable of having splicing fit with the stator tooth of the stator core (20), and the stator winding (30) comprises an insulating framework (310) and varnished wire (320) which winds the outer surface of the insulating framework (310). The head face width of the tooth top of the stator tooth is smaller than the head face width of the tooth root part of the stator tooth. Support slide fasteners are arranged on two lateral tooth walls of the tooth top position of the stator tooth, and a limit slide fastener is arranged between each support slide fastener and the tooth root of the stator tooth; limit grooves (317) capable of having splicing fit with the limit slide fasteners are formed in the inner side wall of the stator winding (30). The permanent magnet synchronous motor is capable of improving the groove fullness of the motor to effectively guarantee the torque and power output by the motor.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a permanent magnet synchronous motor. The invention also relates to a new energy vehicle with the permanent magnet synchronous motor. Background technique [0002] With the continuous upgrading of my country's automobile industry, the automobile industry is no longer dominated by traditional gasoline vehicles, and new energy vehicles, as a rapidly rising new army, are constantly challenging the status of gasoline vehicles. [0003] As we all know, there are many differences between new energy vehicles and traditional gasoline vehicles; in simple terms, traditional gasoline vehicles use gasoline as the power source, while new energy vehicles use electricity or solar energy as the main source of power. At present, most new energy vehicles use plug-in hybrid power; its key component is the permanent magnet synchronous motor. Therefore, the performance of permane...
