Power density improvement due to Rotor Flux screens in an SRM with a higher number of Rotor Poles than Stator Poles

This paper investigates the effect of rotor flux screens (conducting screens) on performance switched reluctance motors with a higher number poles than stator poles. A high decreases torque ripple, which is desirable for electric vehicle applications. The conducting fill interpolar gaps forming cylindrical hence alleviating windage losses, especially effective at speeds. screen thickness and material electrical conductivity current rise time, developed torque, output power studied. procedure calculating value unaligned inductance screened using tube method presented. Finite element analysis results different cases confirm effectiveness in improving capability, motors. Received: 11 January 2023 Accepted: 03 May Published: 30
