The invention discloses a wheel hub motor with a built-in control system. The motor comprises a casing, a motor shaft, a stator assembly and a rotor assembly. The casing is a hollow cavity body, the stator assembly is located in the casing. The rotor assembly is connected with the casing and sleeves the stator assembly. The motor shaft penetrates through the casing, the stator assembly, the rotorassembly, the rotor assembly and the casing rotates around the stator assembly by taking the motor shaft as an axis, a motor wire assembly penetrates through the motor shaft and is connected with thestator assembly, a control system is further comprised, the control system is arranged on the stator assembly, and the control system is connected with the motor wire assembly. The control system is arranged on the stator assembly and is closer to a core part of the motor in space, more accurate control and monitoring can be achieved, the control system can be located in the motor through the structure, the circuit arrangement of a whole vehicle is simpler, and the structure is more compact. And the two heating components which are the control system and the stator assembly are arranged together and then are subjected to centralized heat dissipation, so that the heat dissipation efficiency is improved.
Description
technical field [0001] The invention relates to a motor, in particular to a hub motor with a built-in control system. Background technique [0002] At present, the electric vehicle control system on the market is generally installed separately from the motor, and most of them are installed on the handlebar or seat. This installation method keeps the control system away from the motor, and it is difficult to realize the real-time control of the motor by the control system. , precise control, and real-time monitoring of motor parameters cannot be realized. At the same time, because the control system and the motor are separated from each other, an external line is required to connect the two, which makes the wiring layout and body assembly of the vehicle very complicated, and the controller is often accompanied by the heating of the line during the working process, which is easy to cause fire and has Security risks. At present, although some manufacturers try to set the cont...
