Modelling and analysis of the low-power 3-phase switched reluctance motor

Abstract

Switched reluctance motors (SRMs) are still under development to maximise their already proven usefulness. A magnetic circuit of the SRM can be made of soft magnetic composites (SMCs). The SMCs are composed of iron powder with dielectric and have a lot of advantages in comparison to commonly used electrical steel. The paper deals with the modelling and analysis of the SRM produced by Emerson Electric Co. for washing machines. Numerical calculations and modelling were done using the FEMM 4.2 program. Magnetic flux densities and magnetic flux lines were calculated, as well as electromagnetic torque and inductance for changing the position of a stator to a rotor. The obtained results were compared with other measurement results and are quite similar. The developed numerical model will be used for the project of a motor with an SMC magnetic circuit.
