Problems solved by technology

Restricted by foreign patents and the technology blockade of motor giants, it is difficult to find first-hand information on modular motors. Only limited information can be found through some reports, and the use of surface-mounted permanent magnet hub motors cannot provide sufficient reluctance rotation. Moment, poor adaptability to complex working conditions such as overload climbing, high-speed cruising, rapid acceleration and deceleration, and frequent start and stop
[0004] The current cooling system used by the wheel hub motor and the drive controller is a series cooling method. The cooling water flows through the cooling pipeline of the motor, then flows into the cooling pipeline of the drive controller, and finally returns to the cooling water tank to form a cycle. However, after the cooling water passes through the motor , the temperature rises more, and the cooling effect on the controller becomes very poor; at present, there are still many controllers of the drive system that use the most primitive natural air cooling for heat dissipation, and the performance for complex working conditions is even worse

Description

technical field [0001] The invention belongs to the technical field of pure electric vehicles, and in particular relates to a highly integrated modular wheel hub motor. Background technique [0002] In-wheel motor is a motor in the form of inner stator and outer rotor. Its power, transmission and braking devices are integrated in the hub, which greatly simplifies the mechanical parts of electric vehicles. Compared with traditional motors, it has good mobility, high Efficient transmission, high utilization of interior space and good dynamic performance. [0003] At present, most in-wheel motors are arranged separately from their drive controllers. The drive controllers are arranged on the frame of the electric vehicle, and the drive controllers are connected to the motor for driving. There are too many wiring harnesses and interfaces, which is more troublesome to arrange. Subject to foreign patents and the technical blockade of motor giant companies, it is difficult to find ...
