Abstract

An internal circulation oil cooling motor includes a closed motor body, a cooling oil delivery pump assembly, a heat exchanger, a cooling fan, and a cooling oil regulating device. It is characterized in that: the closed-type internal circulation oil cooling motor is divided into two oil closed-loop cooling circuits to separately cool the outer circumference of the motor stator and the end of the winding, as well as the inner circumference of the rotor and the stator, so as to realize efficient cooling of the motor and achieve The purpose of the motor is small size, light weight, high efficiency and energy saving.

Description

technical field [0001] The invention relates to an internal circulation oil cooling motor. Background technique [0002] At present, the cooling of small motors adopts a single cooling method, that is, external cooling method and internal cooling method. External cooling is to use wind heat dissipation or medium to cool the motor shell, and then realize the cooling of the motor stator and coil through heat conduction and heat dissipation. Internal cooling usually adopts the method of setting air ducts in the motor housing to cool the stator and coils. However, none of the above-mentioned cooling methods can meet the requirements of high-efficiency cooling, especially how to effectively cool the rotor of the motor is a technical problem. The rotor of an asynchronous motor has low voltage and high current temperature rise, and the stator to rotor of a synchronous motor Radiant heat is also a problem. In particular, the current development of pure electric vehicles has more s...
