Abstract

This paper discusses the torque and magnetic field characteristics of switched reluctance machine when excited with smoothed trapezoidal current at its winding. Switched reluctance motor observed in this paper is a 450 W, 8/6 type switched reluctance machine commonly used in household applications. To observe the torque ripple electric field distribution in the design of this motor, the finite element method is used. The simulation result suggests an average torque of 3.1 Nm per electric cycle and a ripple of 5 Nm. The maximum magnetic field interaction happens the highest at an angle of 2.75° from its starting point. The duty cycle effect is observed to see the correlation between the cycle and developed torque. 22% duty cycle is chosen as the most suitable choice to drive switched reluctance model due to its optimal torque ripple characteristics. Then, it is concluded that this simulation’s characteristic is valid for further study of this machine.

非晶钢、超铁芯和软铁对8/6开关磁阻电机磁场分布和转矩脉动的影响

本文讨论了开关磁阻电机绕组受平滑梯形电流激励时的转矩和磁场特性。本文所观察到的开关磁阻电机为450w, 8/6型开关磁阻电机，通常用于家庭应用。为了观察电机设计过程中转矩脉动电场的分布，采用了有限元法。仿真结果表明，每电循环平均转矩为3.1 Nm，纹波为5 Nm。最大磁场相互作用发生在距其起点2.75°角处。观察占空比效应，以查看循环和开发转矩之间的相关性。由于22%占空比具有最佳的转矩脉动特性，因此选择22%占空比作为驱动开关磁阻模型的最合适选择。最后得出结论，该仿真特性对该机床的进一步研究是有效的。
