Abstract

The invention discloses a motor heat dissipation structure, which relates to the technical field of motors and comprises a casing, a rotating shaft, a rotor, a stator and a heat dissipation disc. The high-heat-conductivity cooling resin is filled in the heat dissipation disc, the exposed coil is coated with the cooling resin, the coil is subjected to heat absorption and cooling in a direct contact mode, on the basis, the inner heat dissipation grooves and the outer heat dissipation grooves are formed in the heat dissipation disc, the cooling resin is located between the inner heat dissipation grooves and the outer heat dissipation grooves, and the heat dissipation efficiency is improved. When the cooling liquid flows through the inner heat dissipation grooves and the outer heat dissipation grooves, the cooling resin is cooled, the heat absorption and cooling effect of the cooling resin on the coil is enhanced, and then the cooling liquid absorbs heat and cools the stator after flowing through the cooling grooves of the stator. Double cooling of liquid cooling and resin cooling is achieved, the cooling effect is enhanced, and the motor is effectively cooled.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a heat dissipation structure of a motor. Background technique [0002] The motor includes a housing, a rotor, and coils for forming a magnetic field to drive the rotor to rotate, the coils being arranged in the stator. During the operation of this type of motor, after the coil of the stator passes through a large current, the heat generated by the coil and the stator will also increase. If the heat cannot be dissipated in time, it is easy to cause excessive temperature to damage the motor. [0003] At present, the heat dissipation structure and method used by the motor are air cooling and liquid cooling. Among them, the air cooling is only suitable for cooling the motor by cooling the motor casing, and is not suitable for cooling the inside of the motor, because the air cooling is easy to remove external impurities. Wrapped inside the motor, affecting the motor work. Th...
