Problems solved by technology
Poor thermal conductivity, the heat of the copper wire winding cannot be quickly conducted to the iron core through the skeleton and slot paper
[0005] However, in the prior art, traditional methods such as resin and injection molding are generally used to dissipate heat from the stator. This heat dissipation method has a low thermal conductivity and limited heat dissipation inside the stator, so it cannot effectively dissipate heat from the stator.

Description
technical field [0001] The application belongs to the technical field of electric motors, and in particular relates to a heat dissipation device, a stator structure and an electric motor with the same. Background technique [0002] At present, with the large-scale application of automation equipment, the demand for servo motors is increasing day by day. Moreover, with the miniaturization of intelligent equipment, higher requirements are placed on the volume of servo motors, and major motor manufacturers are trying their best to shorten the overall length of servo motors. Followed by the increase of the power density of the servo motor, the length of the motor is gradually shortened, but the power remains unchanged, so that when the heat generation of the motor remains unchanged, the heat dissipation area gradually decreases and the internal temperature rise gradually increases. This puts forward higher requirements on the heat dissipation of the servo motor. The main heat ...
