摘　　要：齿层比磁导法是目前步进电机电磁转矩的主要计算方法,提出了一种新型电磁转矩分析计算方法—齿层计算转矩法。首先给出步进电机齿层计算转矩的概念,同时在理论上证明了采用齿层计算转矩法计算步进电机电磁转矩的正确性,然后给出了齿层计算转矩法用于步进电机电磁转矩及其他性能分析计算的步骤,最后针对磁阻式步进电机和混合式步进电机,分别采用齿层比磁导法、齿层计算转矩法和电磁场有限元法进行对比研究。结果表明,齿层计算转矩法与现在通用的齿层比磁导法相比具有简单实用、计算精度高的特点。Tooth-layer specific permeability method is so far the main method for calculating of electromagnetic torque in stepping motors,a novel method for the analysis and calculation of electromagnetic torque was proposed which is called the tooth-layer calculated torque(TLCT)method.The concept of TLCT was defined firstly and its correctness when used to calculate the electromagnetic torque was proved theoretically at the same time.Then the way to use the TLCT method in calculating electromagnetic torque and other performance parameters in stepping motors was described.Finally,a comparative research among the tooth-layer specific permeability method,the TLCT method and the finite element method(FEM)was carried out,with results showing that the TLCT method is characterized by being simple and practical as well as high accuracy compared with the tooth-layer specific permeability method.
