Embodiment Construction

[0068] The specific implementation manners of the present application will be clearly described below in conjunction with the accompanying drawings.

[0069] see figure 1 , the embodiment of the present application provides a motor cooling system 200 including the motor 100 , the motor cooling system 200 can be applied in a mechanical device to dissipate heat and cool the motor 100 . For example, the mechanical equipment may be any mechanical device such as electric vehicles, processing equipment, and engineering machinery.

[0070] Specifically, heat dissipation and cooling of the motor 100 can be achieved by providing a flow channel in the motor cooling system 200 and using coolant as a heat exchange medium to allow the coolant to flow in the flow channel to take away heat generated by the motor 100 . For example, the motor 100 may be, but not limited to, a permanent magnet synchronous motor, an asynchronous induction motor, or a generator. The coolant can be lubricating o...

Abstract

The invention provides a motor, a motor cooling system and an electric vehicle. The motor comprises a rotor, and the rotor comprises a rotor iron core, a first end cover and a second end cover, wherein the first end cover and the second end cover are connected to the two ends of the rotor iron core respectively; the first end cover is provided with a liquid inlet flow channel, the rotor iron coreis provided with a liquid passing flow channel, the first end cover or the second end cover is provided with a liquid outlet flow channel, the liquid inlet flow channel is communicated with the liquidpassing flow channel and the space outside the rotor, and the liquid outlet flow channel is communicated with the liquid passing flow channel and the space outside the rotor. An outlet of the liquidoutlet flow channel faces the stator winding, and the liquid inlet flow channel, the liquid passing flow channel and the liquid outlet flow channel form a rotor flow channel for cooling liquid to flowthrough. According to the technical scheme, the processing cost can be reduced on the basis of ensuring the heat dissipation reliability of the rotor of the motor.

Description

technical field [0001] The present application relates to the technical field of electric vehicles, in particular to a motor, a motor cooling system and an electric vehicle. Background technique [0002] With the development of electric vehicles, the electric vehicle assembly is developing towards high speed and high power density, and the heat consumption density of the motor is also getting higher and higher. Heat dissipation has become an important challenge in motor design. Whether the motor can perform good heat dissipation It directly affects the working reliability of the motor and the performance of the whole vehicle. The motor includes a rotor, and usually requires a corresponding heat dissipation design for the rotor. However, the heat dissipation design of the rotor of the traditional motor is expensive and has low reliability. Contents of the invention [0003] Embodiments of the present application provide a motor, a cooling system for the motor, and an elect...
