Background

Small power motors typically employ a sealed cooling configuration, and losses from the components during operation of the motor are primarily transferred in the form of heat through the housing in a radial direction to the external environment. Along with the development of the modern motor design industry towards small volume and high power density, the heat generated in unit operation time is increased, and the heat generated in the motor during working cannot be timely transferred to the external environment due to the limited contact area of the heat dissipation fins on the traditional shell and the external air area, so that the temperature rise of each component is higher. The condition not only causes the running efficiency of the motor to be reduced and the output power to be reduced, but also causes the insulation material in the motor to be rapidly aged, and seriously threatens the normal running of the motor.
