Design Selection Criteria of Single Phase Induction Machine

Abstract

This paper examines how important design factors, particularly capacitance values and stator and rotor slot dimensions, affect the performance of single-phase induction motors (SPIMs). Results indicate that while increasing stator slot width decreases starting current, it also decreases efficiency and torque Similarly, larger rotor slots increase starting current while reducing starting torque and efficiency. Although it increases capacitor losses, adjusting capacitance improves efficiency, power factor, and starting torque. In order to balance efficiency and performance, ideal ranges for capacitance and slot size are proposed, offering guidance for better SPIM design.
