NOVELTY - The utility model belongs to the technical field of motor, claims a high speed motor with self-radiating function, the high speed motor is a rotating motor, the motor shell is provided with an annular radiating cavity, the radiating cavity is surrounded outside the stator, the axial direction of the radiating cavity is consistent with the axial direction of the rotor, the radiating cavity is placed with the graphene and the magnetic fluid. The utility model abandons the original structure of liquid cooling heat dissipation, cancels the setting of the liquid cooling channel, greatly reduces the complex degree and volume of the motor, cancels the common oil pump of common liquid-cooled high speed motor, lubricating oil tank, oil pipe structure, so that the high speed motor has simple structure, easy installation, strong stability, and there is no common faults such as oil leakage and so on. in the motor operation process itself will generate the change magnetic field to drive the magnetic fluid to move, so as to impact to drive the movement of the graphene, making graphene position of the radiating cavity move, the heat of the high speed motor is brought to the surface of the motor shell, realizing the self-radiating of the motor.
