The new energy vehicle motor loading testing equipment is a device designed to test the performance of permanent magnet drive motors, which are one of the three major types of new energy vehicles. By using a variable frequency AC power dynamometer for loading, the system collects various data of the motor for analysis and drawing curves, assisting researchers in understanding the performance of the motor and conducting related research. It has functions such as transient loading, anti drag switching, dynamic stall, and load start, and can accurately control the speed, torque, and power of the power dynamometer in steady-state and dynamic conditions in a closed-loop manner. The user edits the working condition table according to the experimental requirements, which contains information such as input speed, loading torque, time, etc. The driving torque and speed are applied to the input motor according to the input parameter values. After a working condition is completed, the system prompts according to the requirements of the next working condition table, and controls the driving motor and loading motor according to the speed and torque of the next working condition respectively.
