Based on the theory of electromagnetic field electromagnetic field that the angle position control PC controlled of SRM was numerical researched by finite element method. Then the curves of torque phase current and flux linkage and other parameters were obtained and analyzed. Moreover the calculated results were compared with the test data. Rationality of the 2D simulation model which considers the influence of magnetic field at the end of the winding is verified and theoretical basis for research of temperature rise the noise and SRM optimization are provided.
