Research on the Loading Method of Motors Based on the AC Synchronous Generator

Abstract

This paper presents a motor loading method using an AC synchronous generator (abbreviated to ACSG) as the load device. By coaxially connecting ACSG rotor to the motor rotor, the motor provides power for ACSG. We analyze the electromagnetic torque characteristics of ACSG. By controlling the electromagnetic torque of ACSG, the motor receive constant or variable load torque. The load torque of the motor can be measured by the system and sent to the controller as feedback. The changing trend of the set torque and the load torque are similar. The feasibility of the loading method can be examined with the input power of the motor. According to the actual motor load changes, we can change the electromagnetic torque of ACSG to simulate real conditions.
