Winding Magnetization Design of Single-Phase Capacitor-Run Induction Motor for Submersible Pump Application

This article provides a systematic stator winding design scheme that can effectively improve the operational efficiency of commercial single-phase capacitor-run induction motors (IMs). Without changing the circuit components and structural constraints, the motor’s stator windings will be rearranged based on the devised theoretical basis and design objectives. The design scheme supported by the finite-element emulations will be supplied to show the efficiency improvement of a commercial single-phase two-pole IM. In addition, experimental hardware validations will be accomplished from the motor with rewound stators, and evident performance advances from measurements confirm the design.
