针对目前计算开关磁阻电机径向力的虚位移法比较繁琐且影响计算的快速性等问题,提出一种新的计算方法.依据麦克斯韦张量法,给出定子极径向力的数学模型,采用Ansoft软件计算径向力,并对一台样机进行了仿真计算.结果表明,该方法应用简便,计算快速,计算精度满足要求.结果准确地描述了电机径向力的特性,验证了所给方法的有效性.
Because the method of virtual-work for the calculation of the radial force for switched reluctance motor is complex and low efficient,a new method of analysis is proposed.Based on Maxwell stress tensor method,the stator radial force mathematical model was given,and then the radial force of prototype was calculated with the help of Ansoft.The result reveals that the method is simple and high efficient.The accuracy of calculation meets the requirements,and precisely describes the characteristic of the radial force and illustrates the effectiveness of the proposed method.
