单绕组无轴承开关磁阻电动机绕组电流计算

摘要

在阐述双绕组无轴承开关磁阻电动机(BSRM)的数学模型以及工作原理的基础上,提出运用现有的双绕组无轴承开关磁阻电动机理论成果,结合磁势相等的等效原理,建立了单绕组无轴承开关磁阻电动机各绕组电流的数学模型,同时用有限元分析了该模型的正确性,为单绕组无轴承开关磁阻电动机控制策略的研究提供新的视角.%The principle of bearingless switched reluctance motor was briefly introduced. A method which uses the theoretical results of double winding bearingless switched reluctance motor and equivalent principle was put forward, and the calculation formula of single winding bearingless switched reluctance motor was deduced. Finite element simulation results show the validity of the method. This offers a new perspective to control the single winding bearingless switched reluctance motor.
