Abstract
Synchronous reluctance (SynRel) motors are gaining importance in various industrial applications owing to its magnet free configuration, ease of service, reduced thermal stress on the rotor. As the working of synchronous reluctance motors is based on reluctance torque, the choice of electromagnetic steel laminations plays a vital role in the electromagnetic performance of the motor. This paper presents a comprehensive report on the performance of synchronous reluctance motors with various grades of electromagnetic cold-rolled non-grain-oriented (CRNGO) steel laminations. The performance study includes the analysis of average torque, power losses, and percentage torque ripple of different electromagnetic steels. Seven different grades of electromagnetic materials are studied for the same motor geometry. The modelling is based on finite element analysis-based CAD tool, MagNet and MotorSolve. Based on the performance study, it is found out that M-19 produces higher average torque; torque ripple is lower in M-1000, and iron loss is lower in N020-type electromagnetic steel.
