Integrated controller module in motor of electric vehicle

Abstract

The invention discloses an integrated controller module in a motor of an electric vehicle, and the module comprises a motor hub which is arranged in the electric vehicle; a rotor and a stator are arranged in the motor; the stator is arranged in the center of the motor hub; the controller module is further arranged in the motor; a control main board is arranged in the controller module; the controller module is fixedly arranged on the stator; a controller cover is further arranged on the surface of the controller module; the controller cover and a motor cover are fixed together and rotate synchronously. According to the integrated controller module in the motor of the electric vehicle, the controller which is originally arranged outside is arranged in the motor of the electric vehicle, so that leading, gluing, waterproofing and other procedures between the controller and the motor are saved, the controller production and the assembly process of an electric vehicle manufacturer are simplified, the complicated assembly harness of the complete vehicle is reduced, the stability of the complete vehicle is effectively improved, and thus the electric vehicle has the advantages of simplicity in production, high safety and long service life compared with a traditional complete vehicle.

Description

[0001] technical field [0002] The invention relates to the field of motor controllers, in particular to an integrated controller module in an electric vehicle motor. Background technique [0003] Electric vehicle motors have different forms according to their use environment and frequency of use. Different forms of motors have different characteristics. Electric vehicle motors can be divided into brushed motors and brushless motors according to the electrical form of the motor. Type, the existing brushless motor and the controller are both independent units, which are connected through the motor phase wire and the Hall wire. Due to the relatively large phase current and the copper connector is easy to heat and oxidize, the contact resistance of the copper connector increases- The calorific value is also gradually increased. In severe cases, the plastic parts of the connector will melt, and if the materials are poor, it may even catch fire, which poses a great safety hazard...
