The high-speed drive end achieves a maximum speed of 20,000 RPM with a rated torque of 530 Nm. The load motor power is customizable, and the system is equipped with an environmental chamber, temperature control system, battery simulator, and power analyzer. This setup supports the development and testing of electric gearboxes, motors, and powertrains by conducting fatigue life tests, high-speed tests, efficiency tests, high-temperature performance tests, low-temperature start tests, dynamic durability tests, dynamic sealing tests, differential reliability tests, standard condition tests (NEDC, WLTC, etc.), and custom cycle condition tests.
