TL;DR: This article investigates maximum possible torque improvement in a two-pole surface permanent magnet synchronous machine with a reduced magnet span, which causes production of highly nonsinusoidal back electromotive force (EMF).

TL;DR: The paper investigates sensorless field-oriented control of a two-pole surface mounted permanent magnet synchronous machine (PMSM) with a symmetrical nine-phase winding configuration with high-magnitude low-order harmonic spectrum, with third-harmonic magnitude almost equal to the fundamental.

TL;DR: In this paper , the authors proposed a methodology for computing the efficiency maps of induction machines (IMs) operated in wide torque-speed ranges, based on the IM equivalent circuit defined in the rotor dq coordinates.

TL;DR: In this paper, the authors present a methodology for computing the efficiency maps of three-phase induction motors based on the conventional machine equivalent circuit to quickly obtain a set of efficiency maps at different machine temperatures and supply voltage levels.

TL;DR: In this paper, the authors discuss alternative machine solutions reported in literature that combine advantages of both permanent magnet machines and wound field synchronous machines, and compare both performance and constructive complexity in light of their perspective use in traction applications.
