Abstract

The invention relates to the technical field of motors, in particular to a motor stator and a driving motor. The motor stator comprises a stator body, stator teeth, a first tooth tip and a second tooth tip. One end of each stator tooth is connected with the stator body, the other end of each stator tooth is connected with the first tooth tip and the second tooth tip, any stator tooth is provided with two adjacent stator teeth, the first tooth tip faces one adjacent stator tooth, and the second tooth tip faces the other adjacent stator tooth. In the direction between the two ends of the statorteeth, the height of the first tooth tips is larger than that of the second tooth tips. The height of the first tooth tip is greater than that of the second tooth tip, and the area of the first toothtip is greater than that of the second tooth tip in the section perpendicular to the axis of the motor stator, so that the output torque in one rotating direction can be increased, and the rotating direction is used for a rotating direction with a relatively large rotating peak torque requirement; waste of the rotating torque output capacity of the driving motor can be reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor stator and a driving motor. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. The main function of the motor is to generate drive torque as a power source for electrical appliances or various machines, such as a drive motor for a car's power source. When the drive motor is in use, there will be a situation that the peak torque demand for one of the forward rotation and the reverse rotation is relatively large, and the peak torque demand for the other rotation of the forward rotation and the reverse rotation is small. In the prior art, the drive motor is forward The forward rotation peak torque is equal to the reverse rotation peak torque, which causes a waste of output capacity of the drive motor's rotation torque. Contents of the invention [0003] Therefor...
