摘　　要：介绍了永磁感应子式步进电动机静特性的场路结合计算方法 ,建立了步进电动机的磁网络计算模型 ,其中关键模型“齿层单元”采用二维磁场有限元来计算 .样机的实验验证表明 ,采用场路结合计算法 ,数学模型简单实用 。The calculation method in combination with the magnetic field and magnetic circuit is presented in this paper to calculate the static characteristic of PM induction stepping motor. The magnetic network of the motor is established and the key calculation model, 'The Tooth Layer Unit', is analyzed with the 2 D finite element method. The test and the calculation result to a prototype motor shows that the method is practical and effective and that the calculation model can meet the precision need of engineering.
