Problems solved by technology

However, the oil-proof breather valve and vent pipe used in this solution are exposed to the outside, which not only has hidden dangers of liquid leakage, but also causes hidden dangers to the service life of wire components. Therefore, the heat dissipation scheme adopted has hidden dangers in quality. After the electric vehicle motor is integrated with its controller, there will still be a risk of electromagnetic interference. At the same time, other functional control modules of electric vehicles, such as anti-theft modules, vibration modules and DCDC power modules, how to solve the problem of integrated control layout and other issues

Abstract

The invention discloses a motor controller integrated assembly for an electric vehicle and the electric vehicle with the motor controller integrated assembly. The motor controller integrated assembly comprises a permanent magnet rotor assembly which is integrated with an electric vehicle hub and a motor shell, and a stator assembly which is located at the inner periphery of the permanent magnet rotor assembly and is integrated with a motor shaft, a controller used for achieving driving control over the motor is installed on the end face of the stator assembly, the motor shell is provided with a liquid injection opening used for injecting insulating cooling liquid, meanwhile, an air duct extending from the interior of the motor shell to the exterior of the motor shell is arranged in the motor shaft, and an air duct port located in the motor shell is connected with an air vent valve. According to the motor controller integrated assembly, the heat dissipation problem of the motor controller integrated assembly for the electric vehicle is effectively solved, so that the application process of the motor controller integrated assembly for the electric vehicle is powerfully promoted, and standardization and series modularization of motor controller products are achieved.

Description

technical field [0001] The invention belongs to the field of drive control of electric vehicles, and in particular relates to a motor controller integrated assembly for an electric vehicle, and also relates to an electric vehicle to which the motor controller integrated assembly is applied. Background technique [0002] With the technical development of motor drive control technology, subject to the strict compact installation requirements, in the field of household appliances and power tools, the motor and controller have basically realized integrated installation, and because of the field of household appliances and power tools, the motor's The working power is small, so after the motor and the controller are integrated, the problem of heat dissipation is small, which has become a key factor for the integration of the motor and the controller in these fields. [0003] Specifically for the field of electric vehicles, since the brushless permanent magnet synchronous motor ha...
