EME offers easy operation, quick spec adjustments, motor failure simulation, no rotating parts, short development cycles, and energy recycling. It features motor modeling, numerical computation, delay-time compensation, current control, harmonics reduction, and speed feedback. The 30 kW prototype connects directly to motor drives for varied torque/speed tests.

The scientific breakthroughs of this work include: (1) Establishing a dynamic model that combines both mechanical and electrical behaviors of the motor. (2) Achieving fast and stable electrical sensing as well as the output of the emulated motor information. (3) Implementing a high-frequency, high-power power converter.

The EME replaces traditional testing with low energy use, no noise, and high safety, boosting R&D efficiency and reliability. It cuts costs by 50–80% and timelines by 50%, handling diverse test scenarios. Scalable for EVs, energy storage, and renewables, EME is set to be a key power electronics technology, enhancing global competitiveness and value creation.
