Research on measurement of power angle and D-Q axis reactance parameters of REPM synchronous motor

Research on measuring method of power angle and D-Q axis reactance parameters of rare earth permanent magnet synchronous motor (REPM) is presented. Singlechip measuring instrument of power angle and measuring installation of voltage integration method have been developed. Based on the instrument, methods of direct load, pure induction load and voltage integration methods are also used for the measuring research of D-Q axis reactance parameters. A rational measuring solution is given by comparison and analysis of measuring results.
