Embodiment Construction

[0027] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0028] Such as Figure 1 to Figure 7 As shown, the integrated motor of the first embodiment includes: a motor main body 10 and a motor controller 20. The motor main body 10 includes a casing 11 and a rotor assembly 12 passing through the casing 11. The motor controller 20 is disposed at the rear end of the motor main body 10 and forms a rear end cover assembly. The motor controller 20 has a first cooling liquid channel 21, a cooling liquid connection channel 22, and a second cooling liquid channel 23. The rotor assembly 12 has a third cooling liquid channel 121. The housing 11 has a fourth cooling liquid channel 111. The liquid channel 21, the third cooling liquid channel 121, the coolin...

Abstract

The invention provides an integrated motor and an automobile with the same. The integrated motor comprises a motor main body and a motor controller, wherein the motor main body comprises an enclosureand a rotor assembly, the rotor assembly is arranged in the enclosure in a penetrating way, the motor controller is arranged at a rear end of the motor main body, a rear end cover assembly is formed,the motor controller is provided with a first cooling liquid passage, a cooling liquid connection passage and a second cooling liquid passage, the rotor assembly is provided with a third cooling liquid passage, the enclosure is provided with a fourth cooling liquid passage, a first cooling passage, the third cooling liquid passage, the cooling liquid connection passage, the fourth cooling liquid passage and the second cooling liquid passage are sequentially connected so that the integrated motor is cooled by a cooling liquid. With the integrated motor provided by the technical scheme, the problem of relatively large volume of the integrated motor in the prior art is effectively solved.

Description

Technical field [0001] The present invention relates to the technical field of electric motors, and in particular, to an integrated electric motor and an automobile having the same. Background technique [0002] The utility model relates to an integrated power assembly of a controller and a driving motor. In the assembly system, the position of the controller is located on the motor axis and in the direction opposite to the motor output shaft. [0003] Due to the high temperature generated by the stator of the drive motor during operation, it is necessary to dissipate heat from the stator. In particular, for the AC asynchronous induction motor, due to its special working principle, the rotor generates a larger current during operation, which also To generate higher temperatures, the stator and rotor systems need to adopt a reasonable cooling scheme for heat dissipation to ensure the balance of motor work. At the same time, the switching electronics in the controller assembly, such...
