Performance Analysis of Single-Phase Inverter-Fed Permanent Magnet Synchronous Motor with Ladder-Connected Winding

This paper proposes a new permanent magnet synchronous motor (PMSM) with ladder-connected winding. The proposed PMSM is able to drive only by a single-phase H-bridge inverter thanks to an intrinsic wave propagation effect of the LC ladder circuit configuration. A mathematical modeling of the circuit is presented. To validate the effectiveness of the proposed PMSM, phase current and torque characteristics are calculated numerically from the derived circuit equations.
