Effects of Amorphous Iron and Supercore as Core Material on Electric Field and Torque Characteristics for 450W 8/6 Switched Reluctance Motor

To prevent dependency to permanent magnet material for electric machinery construction, there has been an increase on SRM research to enhance its characteristic to be able to compete against permanent magnet motor. In this paper, different core material is tested to see how it will improve SRM characteristics. High silicone steel, also known as super core and new material, Amorphous iron is compared to conventional laminated steel on 450W SRM usually used for household appliance. Finite element method is used to analyze torque and magnetic field characteristics. From simulation, it is concluded that amorphous iron and super core is proven to be able to increase maximum torque and average torque by increasing magnetic field. However, this new material is also shown to increase torque ripple and potentially increase noise.
