The upper computer program of the motor controller can be provided to change some parameter settings.
11. The driving motor adopts the domestic mainstream pure electric vehicle permanent magnet synchronous motor. When the three-phase alternating current is connected to the stator coil, the rotating magnetic field will be generated, and the rotating magnetic field will pull the permanent magnet inside the rotor to generate the rotating torque synchronized with the rotating magnetic field. The drive motor does not use idle speed, and even when the vehicle is in a critical state from stationary to starting, it can generate maximum driving torque to ensure smooth operation.
12. Adopting the mainstream domestic pure electric vehicle star network structure VCU vehicle controller strategy. The VCU transmits data to the motor controller, power battery pack BMS, instruments, etc. through the CAN network. The signals of gear position, throttle, brake, water temperature, etc. are transmitted to the VCU through hard wire. After conversion, the VCU transmits the driving signal to the motor controller through the CAN network. The motor controller collects the driving motor rotary signal and converts the high-voltage direct current into three-phase alternating current to drive the vehicle.
13. Adopting high-speed pure electric vehicle single speed transmission, transmission shaft, and brake assembly. The brake assembly drives the real load device through flexible transmission, and the load size can be adjusted separately to reproduce the actual working conditions of the vehicle, such as downhill, flat road driving, uphill driving, half slope starting, turning driving, etc. Enable students to grasp the changes in current and voltage parameters under actual working conditions.
