The electric drive system in the new energy electric vehicle system is an important part of the whole vehicle system. Its basic performance and control effect directly affect the performance index of the whole vehicle, and the motor controller is the core component of the electric drive system. During the operation of electric vehicle, the process of motor controller failure is the process of its technical status change. Once the drive motor or controller fails, the transient torque generated by the motor will affect the stability and power of the vehicle. If it can not be found or repaired in time, it will bring immeasurable losses or accidents. Therefore, the fault diagnosis of electric vehicle motor and controller is of great significance to ensure safety and reduce losses.
Therefore, the performance test and aging test of motor driver are particularly important. The motor simulation load developed by us is designed for the aging occasion of motor driver, which can accurately evaluate the service life and performance of the controller and improve the reliability of product development.
It is made of special materials and technology, with low impedance, small three-phase imbalance and long service life. It supports durability test conditions for more than 3000 hours.
