The multi in one design of hub motor integrates modules such as motor, controller, weighing module, electronic assisted braking, etc. Through leasing, it can achieve multi scenario applications
R&D philosophy:
1.The design concept of the integrated system for motor controllers is derived from the market demand for high efficiency and reliability
2. At present, the control units on the market not only achieve driving functions, but also shoulder the implementation of application functions and cycling experience functions. There are many cable outlets, and the motor and controller are two independent core components installed in two parts of the vehicle body, with phase lines and Hall connections in the middle. The copper loss is severe, the system efficiency is low, and the phase line interface is prone to poor contact, and in severe cases, it may even burn the car, posing a high social security risk, The faultless operation time of the control unit is short, and the market service cost is very high
3. System integration design has achieved the highest electrical efficiency transmission of the system, with very low heat loss and improved system efficiency, which can increase a considerable driving range; Through the Can communication function, the problem of high cost, low quality and efficiency of functional cables has been solved, reducing electrical connection points and improving product reliability
4. The popular saddle gravity sensor in the market has inaccurate gravity fulcrum, and the shock absorber side mounted sensor has low detection accuracy and complex algorithm due to not being on the axial centerline of the vehicle. It is prone to errors in special working conditions. The original axial gravity sensor from Jinfeng perfectly solves the above problems
