摘　　要：对 1 2相电励磁同步电动机的数学模型进行了分析 ,结果表明 :在合理假设的基础上 ,四套绕组输入电流、输入电压以及磁链的 dq轴分量是相等的 ,即四套绕组对总的电磁转矩的贡献是相同的 .据此 ,提出了交交变频气隙磁链定向控制 1 2相同步电动机调速系统的控制策略 .在理论分析的基础上 ,编写了基于 MATLAB/ Simulink的交交变频气隙磁链定向控制 1 2相同步电动机调速系统的仿真程序 ,仿真结果验证了所建模型及控制策略的正确性 .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.
