AbstractSingle-phase induction motors are used in multiple applications in whichhaving the correct value of the capacitor linked to auxiliary winding allows the motor to work effectively. The current study used finite element analysis based on Magnet software to investigate the effect of changing the running capacitor on the performance of a single-phase squirrel cage induction motor with non-uniform stator slots, as well as using AutoCAD to model the stator due to its asymmetrical slots. The design documentation for a 0.5 hp, 36 stator slots, and 48 rotor bars, 25 µF, four-pole tested model are used to simulate the motor. The precision of model outcomes is confirmed successfully by comparing its outcomes of rated current and torque with motor nameplate data. The effect of changing the running capacitor on the performance of a single-phase induction motor is discussed in this study. To demonstrate the simulation's versatility in motor design, the auxiliary branch capacitor was modified (increasing and decreasing) and the effect of each instance on the motor's performance was investigated.
