New energy automobile driving motor performance testing device

The invention provides a new energy automobile driving motor performance testing device, and particularly relates to the technical field of motor performance tests.The new energy automobile driving motor performance testing device comprises a testboard, a dynamometer is fixedly arranged at the upper end of the testboard, a first semicircular cavity disc is arranged above the testboard, and a second semicircular cavity disc is arranged above the first semicircular cavity disc; the eccentric torque testing mechanisms are arranged in the first semicircular cavity disc and the second semicircular cavity disc, and by arranging the eccentric torque testing mechanisms, a tester can freely select to increase or decrease the load weight on the motor shaft under the condition that the motor shaft rotates, so that the performance data of the to-be-tested motor under different eccentric load conditions are tested, and the test efficiency is improved. Therefore, the performance of the to-be-tested motor can be obtained mo
