Summary The E-Motor Emulator is a new type electronic load utilizing both power conversion technologies and high-power high-frequency switching devices to emulate port characteristics of electric motors. Based on an accurate dynamic mathematical model, the emulator can output the characteristics of electric motors under working conditions. It can serve as: (1) An electronic load to the grid (at special power levels). Ideal for studying the characteristics of power system; (2) An E-Motor Emulator to perform functionality, endurance, fault diagnosis, and safety protection testing. Ideal for the R&D process of motor controllers and frequency converters. | Test Items
