摘要
为研究双相励磁8/6极开关磁阻电动机转矩特性,文章根据电机原理和等效磁路法,给出了双绕组间自感、互感公式;利用开关磁阻电动机磁路分割法,求解了8/6极开关磁阻电动机的气隙磁导,进而推导出电机的转矩模型公式。最后,通过有限元仿真结果,证明了转矩数学模型的正确性。研究表明:该转矩数学模型能正确描述8/6极开关磁阻电动机无位置偏移时的转矩输出特性。
In view of the torque of 8/6 switched reluctance motor (SRM) with two-winding excitation, the stator winding'sself and mutual inductance were deduced based on the principle of 8/6 SRM and the method of magnetic equivalentcircuit. Utilizing the method of magnetic field division, the gap permeance of 8/6 SRM was solved, and then the mathematicmodel of torque was derived. Finally, based on the results of finite - element analysis, the validity of the mathematicmodel was verified. The studies show that the mathematic model of torque can describe the output characteristics of 8/6SRM correctly when the motor stays balanced.
