Problems solved by technology

Liquid cooling refers to relying on the coolant to cool the motor body. The liquid cooling method needs to design a special coolant channel for the motor, and needs to pressurize and dissipate the coolant. The cooling effect is good, but the complexity and weight of the system are greatly increased.

Abstract

The invention discloses an outer rotor motor which comprises a motor rotor, cooling blades positioned in the motor rotor and arranged in a rotatable manner, and a blade adjustment device for adjustingthe angle of attack of the cooling blades; multiple cooling blades are provided and are all distributed circumferentially in the motor rotor. According to the outer rotor motor disclosed by the invention, the cooling blades are arranged in the motor rotor to accelerate the flow of a flow field around the motor to cool the motor body; thus, an effect of forcing ventilation and cooling is realizedwithout increasing the structural complexity and obvious weight, and the cooling effect of the motor is improved.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular, the invention relates to an outer rotor motor. Background technique [0002] A motor is an electromechanical product that uses a magnetic field as a medium to convert mechanical energy and electrical energy. During the working process of the motor, a large amount of heat will be generated. The heat mainly comes from: the heat generated by the friction between the machines on the contact surface; the heat generated by the resistance of the wire and the resistance of the induced current when the alternating current is conducted in the wire ; Alternating current in the stator core and rotor yoke to produce heat generated by eddy current loss. The heat makes the temperature of the motor rise when it is working, and there is a temperature rise compared with the ambient temperature. When the motor works in an environment with high temperature, the temperature of the motor itself is too ...
