Quick heat dissipation motor

Technical Field

The utility model belongs to the technical field of the motor, concretely relates to quick heat dissipation motor.

Background

When the temperature exceeds a certain temperature, the aging process is accelerated rapidly, the temperature is the heat-resistant limit temperature of the insulating material, the winding insulating material of the motor is aged gradually, the insulating property and the mechanical strength are reduced gradually, and the use of the motor is influenced. If insulation breakdown occurs, the motor is burnt out; and a large amount of generated heat is transferred to the shell of the motor, certain potential safety hazards are brought in use, the service life of the motor is finally shortened, and therefore the motor in work needs to be cooled.

SUMMERY OF THE UTILITY MODEL

Not enough to above-mentioned prior art, the utility model provides a quick heat dissipation motor, the purpose is that the leakproofness of the motor for the electric motor among the technical problem prior art of solution is fine, but its radiating effect is poor, and long-time the use can lead to the high temperature of motor, influences the life of motor to bring the potential safety hazard.

The utility model provides a quick heat dissipation motor, concrete technical scheme is as follows:

quick heat dissipation motor, including support, stator module, rim, first end cover and second end cover, the support is hollow columnar structure, and with frame fixed connection, the support both ends are equipped with the fin, the coaxial cover of stator module is established on the support, and with support fixed connection, the rim respectively with first end cover second end cover fixed connection, first end cover the second end cover with the support rotates the connection, the rim first end cover the second end cover with the support forms airtight cavity, stator module is located in the airtight cavity. In the above scheme, the support can directly be given off to the heat that stator module produced, and the support scatters the heat from hollow structure, thereby has strengthened the radiating effect owing to the support both ends are equipped with the fin simultaneously, has accelerated the air convection. In addition, the wheel rim, the first end cover and the second end cover are rotatably arranged relative to the support and serve as a rotor in the motor. Meanwhile, the sealing performance of the motor is also considered when the rim, the first end cover, the second end cover and the outer peripheral surface of the support form a sealed cavity, and the service life is prolonged.

In some embodiments, the outer circumferential surface of the bracket is provided with a mounting groove, and the stator assembly is arranged in the mounting groove and fixedly connected with the bracket through a retaining ring. Stator module cover is on the support to realize through mounting groove and retaining ring with the fixed connection of support, support and frame fixed connection, thereby realize indirectly that be relatively motionless between stator module and the frame.

In certain embodiments, the apparatus further comprises a first bearing by which the first end cap is rotatably coupled to the bracket and a second bearing by which the second end cap is rotatably coupled to the bracket. The first bearing and the second bearing are the basis for achieving a rotation of the first end cap and the second end cap relative to the bracket.

In some embodiments, the device further comprises a first oil seal and a second oil seal, wherein the first end cover and the bracket are sealed through the first oil seal, and the second end cover and the bracket are sealed through the second oil seal. The first oil seal and the second oil seal provide guarantee for the formation of the closed cavity.

In some embodiments, the stator assembly includes a core with windings disposed thereon.

In some embodiments, the magnetic steel is mounted on the rim and located within the closed cavity. The magnetic steel provides a realization condition for the rim, the first end cover and the second end cover to serve as the rotor.
