Equivalent Magnetic Circuit for Switched Reluctance Motor with Strong Mutual Coupling between Phases

The article discusses a switched reluctance motor (SRM) with a strong mutual coupling between phases. The presence of a strong mutual coupling between the phases gives an advantage in the conversion of electrical energy. The SRM power is increased by 5 ... 15%. However, the analysis of this machine by finite element methods is difficult. The article presents a mathematical model, which is based on equivalent magnetic circuit. This approach allows one to take into account mutual coupling of phases, the distribution of magnetic fluxes in the magnetic system of SRM, the saturation of the magnetic system at simultaneous operation of several phases of SRM.
