Abstract

The embodiment of the invention provides a motor, a power assembly and an automobile. The motor can be applied to an electric car / electric vehicle, a pure electric vehicle, a hybrid electric vehicle,an extended-range electric vehicle, a plug-in hybrid electric vehicle, a new energy vehicle, battery management, a motor & drive, power conversion, a speed reducer and the like. The motor is used foroutputting power, and when the motor outputs power, a blocking piece arranged in the motor prevents cooling liquid from making contact with the rotor, so the cooling liquid does not be splashed underthe centrifugal action of the rotor in the rotating process of the rotor, the kinetic energy consumption of the rotor is avoided, the rotating speed of the motor is higher, the power output is larger,and the problem of the kinetic energy consumption of the rotor when the rotor sprays the cooling oil to the end part of the coil under the centrifugal action in the existing motor is solved.

Description

technical field [0001] The embodiments of the present application relate to the field of motors, and in particular to a motor with oil cooling at coil ends, a powertrain and an automobile. Background technique [0002] The motor is an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque. As a power source for electrical appliances or various machines, the motor mainly includes a housing and front covers at both ends of the housing. The thick end cover, the shell, the front end cover and the inner wall of the rear end cover form a cavity, and the cavity is equipped with a stator, a rotor, a coil, and a shaft with one end protruding from the front end cover and the other end connected to the rear end cover in rotation, in which the motor When running at high speed, the coil will generate a lot of heat. For this reason, cold water or oil cooling is often used to dissi...
