Abstract

The invention discloses a motor and a motor air cooling structure thereof. The motor air cooling structure comprises a plurality of fan blades used for being connected to the end of a rotor. wherein the air outlet side of any fan blade is used for facing the rotor. The motor air cooling structure adopts the fan blades to realize air cooling, and compared with liquid cooling, the size and the massof the motor are not excessively increased; besides, the fan blades are driven by the rotor, kinetic energy of the motor during working can be reasonably utilized, structural complexity of the motor and a product where the motor is located is prevented from being increased, and driving burden of the product where the motor is located is also prevented from being increased.

Description

technical field [0001] The invention relates to the field of motor design, in particular to an air-cooled structure of a motor. It also relates to a motor, including the above motor air cooling structure. Background technique [0002] The design requirements of aviation motors include the characteristics of high power, small size, and light weight, that is, aviation motors need to meet the requirements of high power density. The design of high power density will make the thermal load of the aircraft motor higher, that is to say, a large amount of heat energy will be generated when the aircraft motor is running. If the heat energy cannot be taken away in time, it will directly lead to serious problems such as motor insulation drop, insulation breakdown, and permanent magnet demagnetization. Therefore, the heat dissipation problem of high-power-density aviation motors is extremely important. [0003] At present, liquid-cooled cooling methods are commonly used to cool high-p...
