High-efficiency motor

The utility model relates to a high-efficiency motor, which belongs to the technical field of electromechanical products. The energy conversion rate of the existing motor is low. Through the way that the shape of the end part of a groove tooth of a stator core is changed to be approximate to a trapezoid or a rectangular, or the end face of the stator core is provided with a concave groove, the utility model can improve the magnetic induction intensity of local magnetic circuit at the end part of the groove tooth to improve the efficiency of the motor so as to achieve the purpose of energy saving. The utility model can be used for manufacturing new motors, or used for reforming old motors.
