Description
technical field [0001] The invention belongs to the technical field of equipment testing, and in particular relates to a pure electric vehicle motor testing platform. Background technique [0002] At present, the main test contents of pure electric vehicle motors include motor three-phase DC resistance test, withstand voltage test, no-load speed test, no-load current test, power torque test, temperature rise test, efficiency test, stall test, overload capacity test, Maximum working speed, overspeed test, durability test, etc. In China, the pure electric vehicle motor is mainly debugged on the whole vehicle, but due to the limitation of the space of the whole vehicle, it is difficult to check the fault and replace the parts after a fault or problem occurs, and the workload is heavy. Influenced by the weather, the test period is long, the vehicle is unstable, and there are potential safety hazards. In view of this, some domestic research and development institutions have dev...
