| Abstract: | The approach for calculating the torque-angle characteristics of Switched Reluctance Motor (SRM) is analyzed in this paper. According to flux linkage versus current and rotor position characteristic which is obtained by Finite-element analysis, the torque-angle characteristic of determinate current is calculated. The relationship is gained between the torque-angle characteristic and the rate of phase inductance change versus rotor position. A testing stand for the torque-angle characteristics of SRM has been designed and manufactured. The results of experiment verified that the simulation of the torque-angle characteristic was correct. Lastly the application of the torque-angle characteristic for starting-torque performance is discussed. It can be used to optimize the magnetic structure design of SRM. |
