TL;DR: In this paper, the authors investigated methodologies for reducing the permanent magnet (PM) losses in Halbach arrangements and proposed strategies for loss reduction and performance improvements, in terms of torque ripple, total harmonic distortion, efficiency and power density.

TL;DR: In this paper, a comprehensive design procedure for synchronous reluctance machines is presented, where a 5kW, 80000 rpm synchronous machine is considered, and several structural design optimizations have been performed with the aim of finding the optimal trade-off between the rotor geometrical complexity (i.e., computational time) and the electromagnetic performance.

TL;DR: In this article, the authors presented a novel MTP A control strategy of permanent-magnet assisted synchronous reluctance motor (PMaSynRM) implementing a Newton-Raphson-Based Searching Method for improving the control accuracy for optimal current reference.

TL;DR: In this article, a permanent magnet planar motor with moving multilayer orthogonal overlapping windings has been proposed, which can achieve a five-degrees-of-freedom drive using two sets of $x$ -direction windings and two pairs of $y$ -irection windings in a coreless configuration.

TL;DR: In this paper, a detailed analysis of the commutation aspects related to the diode rectifier of a brushless exciter of a 400kVA synchronous generator is presented and an accurate voltage drop prediction model is proposed and validated.
