Liquid cooling motor without external cooling circulation and air propeller propulsion system
Liquid cooling motor without external cooling circulation and air propeller propulsion system
The invention discloses a liquid cooling motor without external cooling circulation and an air propeller propulsion system, and the motor comprises a motor outer rotor, the outer side surface of the motor outer rotor being directly connected with metal blades; a motor inner stator, a center shaft being arranged on the inner side of the motor inner stator, a coil being arranged on the outer side of the motor inner stator, oil throwing guide blades being designed in the motor outer rotor and arranged on the outer sides of metal blades at equal angles, and insulating cooling liquid being arranged on the inner sides of the oil throwing guide blades. The center line of the motor inner stator coincides with the center line of the center shaft. According to the liquid cooling motor without external cooling circulation and the air propeller propulsion system, the protection level of an aviation high-power motor is improved, the environmental adaptability is improved, a semi-liquid cooling mode is adopted for heat dissipation, the heat dissipation capacity is improved, the power density of the motor is improved, and an external radiator is not adopted. The high-heat-conduction metal material fan is used as a heat dissipation surface to reduce the complexity of the system.
