This paper presents a comprehensive simulation-based performance evaluation of a single-phase induction motor (SPIM) equipped with two identical stator windings. The study investigates the influence of this dual-stator configuration on torque, speed, and current characteristics under both no-load and loaded operating conditions. The motor model was developed and simulated using MATLAB/Simulink, employing the d–q axis transformation technique to represent the dynamic electromagnetic coupling between stator and rotor circuits. The simulation parameters correspond to a 1 HP (0.75 kW), 230 V, 50 Hz SPIM with a rated speed of 15000 rpm, stator resistance of 7.2 Ω, rotor resistance of 5.8 Ω, and magnetizing reactance of 0.48 Ω. Under no-load conditions, the motor achieved a steady-state speed of 1492 rpm with a slip of 0.53%, a stator current of 1.86A, and a core loss of 24.3 W. During loaded operation at full load (0.75 kW), the speed reduced to 1438 rpm (slip = 4.1%), while the developed electromagnetic torque increased to 5.12 N-m. The starting torque was observed to be 1.65 times the rated torque, compared to 1.28 times for a conventional single-winding configuration, representing a 28.9% improvement in starting capability. The stator current waveform exhibited a Total Harmonic Distortion (THD) of 4.6%, indicating minimal harmonic pollution and improved electromagnetic balance. The proposed dual-stator configuration demonstrated superior torque smoothness, and reduced vibration, making it suitable for domestic and light industrial applications in single-phase supply environments
