A New Method of Current Density Distribution for Switched Reluctance Machine to Increase Average output Torque

International audience; The electromagnetic performances for two current distribution methods (classical and non-classical) of a 3-phase, 24 stator slots and 16 rotor poles Switching Reluctance Machine (SRM) were compared. The three phases were excited in sinusoidal current mode. The Finite Element Model was used to predict the average torque, the total flux of each phase, the torque ripple, the self and the mutual-inductance of each phase. After the computation, it is shown that the machine with non-classical current distribution has more average torque than the machine with classical current distribution, especially at high current density. Experimental tests have been realized, and a good agreement between the experimental and numerical (FE) results was observed.
