Abstract
The utility model relates to the related technical field of motors of electric motorcycles, in particular to a motor of an electric vehicle, which comprises a motor shaft, first magnetic steel is fixedly connected to the inner side surface of an iron ring, and second magnetic steel is fixedly connected to the inner side surface of the iron ring. According to the electric vehicle motor, through the arrangement of the first magnetic steel and the second magnetic steel, when current enters the winding of the stator 11, the winding of the stator 11 can generate a rotating magnetic field according to the law of electromagnetic induction, and under the interaction of the magnetic field, generated electromagnetic force can drive the motor shaft 1 to rotate, so that electric energy is more effectively converted into mechanical energy; the double-row magnetic steel mode improves the strength of single magnetic steel, the double-magnetic-circuit mode is adopted, the two pieces of short magnetic steel are easy to machine, the manufacturing cost is low, the product cost is reduced, and the cost performance is improved.
