“…The Block diagram operation of SRM is represented in Figure 2 of the rotor is sensed by a sensor represented by angle, 'ɵ 'when ɵ=0 starting point phase A position is un aligned to midpoint of inter polar rotor-gap faces the stator pole.at this position there is no torque and the current is passing in phase A [4][5][6][7]. A torque is required to bring rotor position from unaligned to aligned where the stator and rotor pole centres coincide if the rotor position is ectopic to other side of the unaligned position, unstable equilibrium characterises the mis-aligned situation, since the rotor is in apposition of ace value of inductance when current is passing in an aligned position there is zero torque [12][13][14][15][16][17][18]. Here in this paper, it is mainly focused on rotor material.…”

Switched Reluctance motors (SRM) enthralled many researchers due to their coherent structure and sturdy design switched reluctance motors are, robust, reliable, fault tolerated, efficient, and maximum temperature resistant when compared to other conventional motors. The drift in the power electronic converters enhances the usage of SRM, stator and rotor consisting of projected inward and outward poles the gap between the stator and rotor causes harmonics which cause torque ripples which are deteriorating SRM drives. In this paper, a ferrite rotor is considered which is composed by the different material like nickel, manganese, copper, ferric, and aluminium by manoeuvring combustion of solution and gel method. By availing ferrite material magnetizing and demagnetizing can be done quickly which is essential for SRM rotor.
