A New Hybrid Analytical Model Based on Winding Function Theory for Analysis of Unbalanced Two-Phase Induction Motors

The purpose of this paper is to present a new hybrid analytical model (HAM) based on winding function theory (WFT) for electromagnetic analysis performance one typical unbalanced two-phase induction motor (UTPIM). Different indexes modeling such as distribution, slotting effect, and magnetic saturation can be accurately considered by using the proposed HAM. For obtaining technique, reformulated considering in addition influence distribution. conformal mappings (CMs) are used calculate slotted air-gap length. equivalent circuit (MEC) consider magneto-motive force (MMF) drop iron parts stator rotor due excitation phase-winding. obtained results CMs MEC then utilized WFT inductances respective Transient done field, phase currents, torque, speed lookup table while different capacitors auxiliary phase. In each step, accuracy verified comparing with corresponding through FEM.
