Abstract: As the magnetic field of the switched reluctance motor is highly saturated in operation,the static characteristics are nonlinear and then the mathematic model is difficult to obtain theoretically.In this paper,the static characteristics were detected through experiment.Based on the indirect detected principle,the test circuit was designed to detect the flux linkage,and the transient voltage and current were recorded by oscilloscope.The characteristics of flux linkage and self-inductance were obtained by means of numerical analysis.In addition,the equipment for torque measuring was developed,and the static torque characteristic was achieved by torque sensor.The characteristics of self-inductance and torque are well fitted by using of cubic spline curve,which provide effective evidence for the modeling,simulation and development of the switched reluctance drives. Key Words: Switched reluctance motor;Static characteristic;Detection;Experiment;Flux linkage characteristic;Inductance characteristic;Torque characteristic
