Impact of Laminating Core Materials on Switched Reluctance Motor for Automotive Applications

The amplitude is the chief reason of instability in the switching reluctance motor, despite its importance in vehicle industries due to its salient properties such as mechanically detached gradient coils, lack of permanent magnet, prominent rotor, etc. So a material selection technique adopted to minimize the torque ripple. A 60V, 1500 RPM, 30A switched reluctance motor (SRM) modelled in simulation environment. The analysis performed in rated voltage conditions and the simulated results are estimated from motor solve finite element package. The laminating core material as M19: USS Transformer 72–29 Gage, 20PNF1500, M4: Unisil/alphasil 28 M4, TR66: USS Transformer 52–29 Gage, TR66: USS Transformer 66–29 Gage are utilized to estimate the motor performance needs to be optimised in order to achieve optimal results. As a result of this analysis, the torque ripple is found as same but the average torque various. In this regards, it is found that SRM with M19 is superior than other laminating core material asists SRM.
