Analysis on the model of 12-phase synchronous motor is carried out, and the results indicates that, based on reasonable assumption, the currents, voltages and flux of four set windings are equal. That is, the contribution these four set windings act on the total electromagnetic torque are equal. On the basis of these analysis, the control strategy of 12-phase synchronous motor speed regulating system is advanced. Based on the theoretical analysis, the simulation program of air-gap-flux-oriented control system of cycloconverter-fed 12-phase synchronous motor is compiled and simulation results verifies the correctness of model and control strategy. The theoretical analysis and simulation will be an important reference of further study on system realization.
