Abstract

The invention relates to a test stand system of an electric automobile driving motor, which comprises a dynamometer system and a measured motor system, a speed reducer is installed between the dynamometer system and the measured motor system and used for adjusting the rotary speed of the measured motor in the measured motor system, the electricity of the dynamometer and the measured motor is respectively supplied by two sets of power supplies, a stand motor is arranged in a feedback electric network at an alternating current end, the measured motor can have a wider voltage range, and the standsystem has high efficiency and can carry out hardware-in-loop test for electric automobile power assemblies.

Description

technical field [0001] The invention relates to an electric vehicle drive motor test bench system. Background technique [0002] The drive motor system on an electric vehicle is the core of the entire electric vehicle, and its basic performance and control effects directly affect the performance indicators of the entire vehicle. Therefore, a good drive motor test system is of great significance to the development and application of the motor and its controller. A good test system can not only help developers and application personnel analyze some faults in the process of product debugging and application phenomenon, and can quickly find and solve product problems, and can also make accurate and rapid evaluation of product performance, thereby improving the speed of product development and application efficiency. Considering the diversity of the current vehicle development platforms, the voltage and power levels of the motor system are not unique, so developing a test platfo...
