Structure for motor of electric vehicle

The invention discloses a structure for a motor of an electric vehicle. The structure comprises a shaft, a driving plate, a shell, a stator core coil winding, a bracket plate and a rotor, wherein the driving plate is fixedly sleeved on the shaft end of peripheral; one end of the shell is dynamic hermetically and rotatably sleeved on the periphery on one end of the shaft; the rotor is fixedly sleeved on the shaft; the stator core coil winding is located inside the inner circumference of the rotor; the stator core coil winding is fixedly arranged on the bracket plate; the inner side of the bracket plate along the circumference direction is dynamic hermetically and rotatably sleeved on the shaft; one end of the bracket plate on the outer side along the circumference direction is hermetically and fixedly connected with the other end of the shell; a circular sealing space is formed by the shaft, the bracket plate and the shell; and the rotor and the stator core coil winding are both located in the circular sealing space. The structure for the motor of the electric vehicle is high in continuous stability, the bracket plate is in direct contact with atmosphere, the heat generated by the stator core coil winding is directly emitted to the atmosphere and the radiating speed is high, so that the temperature of the stator core coil winding can be quickly reduced, the power loss of the motor is reduced and the efficiency of the motor is increased.
