Abstract
This paper presents a simulation-based performance assessment of a single-phase induction motor (SPIM) equipped with two identical stator windings, developed and analyzed using MATLAB/Simulink R2023a. The dual-stator configuration was evaluated against a conventional single-stator motor to determine improvements in torque, current, efficiency, and power factor. The mathematical model was derived using d–q axis transformation under standard assumptions of linear magnetic circuit, uniform air gap, and negligible core losses. Simulation results revealed significant performance enhancement with the dual-stator design. The starting torque improved from 1.1 Nm (single-stator) to 1.8 Nm (dual-stator), representing a 63.6% increase in pull-up torque capability. The rated torque also increased from 1.5 Nm to 2.2 Nm, while the steady-state speed rose from 1410 rpm to 1455 rpm, indicating reduced slip and improved electromagnetic coupling. Furthermore, the inrush current dropped from 6.5 A to 4.8 A, and the steady-state current decreased from 4.3 A RMS to 3.5 A RMS, demonstrating lower copper losses and improved thermal performance. The power factor improved due to reduced phase displacement between voltage and current from 36° lag in the single-stator motor to 27° lag in the dual-stator configuration—resulting in better reactive power utilization. The efficiency increased from 70.7% to 80.3%, corresponding to a 13.6% improvement in energy conversion capability. The dual-stator model also exhibited smoother electromagnetic torque-time response with minimal oscillations and reduced torque ripple, thereby enhancing dynamic stability and mechanical robustness. Overall, the results validate that implementing a dual-stator topology in SPIMs substantially improves electromagnetic symmetry, torque performance, and energy efficiency.
