摘　　要：在简要介绍同步磁阻永磁电机的结构及工作原理的基础上,通过有限元技术分析了SR-PM电机的非线性转矩特性,除了基本的转矩特性曲线以外,还深入研究了永磁材料特性、气隙对转矩特性的影响,以及线性模型的误差,并基于转矩特性的分析提出了SR-PM.电机的控制策略。分析结果表明了SR-PM电机相对于其他的同步电机具有独特的转矩特性,需要在控制上给予特殊考虑。Based on the briefly introduction of the structure and principle of the Synchronous Reluctance Permanent Magnetic (SR-PM) Motors, its nonlinear torque characteristics have been investigated using finite-element techniques. Except for the basic torque curves, the influence of permanent magnetic material and gap length on torque has been discussed, as well as the errors of linear model. Then the control strategy is presented based on torque characteristics. The analysis indicates that SR-PM motors have their unique torque characteristics and need special consideration in control.
