开关磁阻电机结构参数对电机性能的影响研究

Study on the Influence of Structural Parameters of Switched Reluctance Motor on Motor Performance

为了研究同功率电机的不同结构对开关磁阻电机性能的影响，采用实验研究法。基于Ansoft电磁仿真软件，从绕组自感、绕组互感、转矩大小及脉动影响、绕组电流等方面，对额定参数相同的四相8/6极开关磁阻电机和四相16/12极开关磁阻电机仿真性能进行了对比分析。结果表明：8/6极开关磁阻电机与16/12极相比，8/6极各相绕组自感值大，互感值大，转矩大，转矩脉动小、电流小。

In order to study the different structure of the same power motor on the performance of switched reluctance motor,the experimental research method is adopted.For the four phase8/6pole and16/12pole switched reluctance motor which have the same rated parameters,the performance of the winding inductance,winding current and torque may be different,the paper makes a comparison and analysis of the issue above.The result shows that comparing to the16/12pole SRM,the8/6pole SRM has more self inductance of each phase,more mutual inductance,torque and less ripple and current density.
