Abstract

The invention discloses a liquid cooling heat dissipation outer rotor motor and an aircraft thereof, the liquid cooling heat dissipation outer rotor motor comprises a stator, an iron core and an outer rotor, and the outer rotor sleeves the iron core; the inner surface of the iron core and the outer surface of the stator are assembled in a sleeving manner; a plurality of staggered rotating flow channels for cooling liquid to flow through are formed in the position, matched with the stator, of the outer circumferential surface of the stator; the outer surface of the stator is provided with an axial groove, and the inner surface of the iron core is provided with a rib matched with the groove. According to the invention, the outer circumference of the stator is provided with a plurality of staggered rotating flow channels, after the iron core and the stator are assembled, a cooling liquid channel is formed between the iron core and the stator, the direct contact cooling of the cooling liquid to the iron core can be realized, the heat dissipation contact area is large, and the cooling efficiency is high.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a liquid-cooled and heat-dissipating outer rotor motor and an aircraft thereof. Background technique [0002] With the continuous promotion of national industrial upgrading, the development of new energy industry is getting faster and faster. As the power density and loss density of motors continue to rise, the heating problem of motors has further emerged. In an electric aircraft, the motor is one of the most critical components of the power system, and the heat dissipation performance of the motor directly affects the safety and stability of the aircraft. [0003] The existing cooling methods of external rotor motors mainly include air cooling and liquid cooling. The heat dissipation efficiency of air cooling is limited. For motors with serious heating problems, the heat of the motor cannot be effectively dissipated by air cooling, and forced liquid cooling is required. [00...
