Design techniques for reducing the cogging torque in surface-mounted PM motors
TL;DR: In this article, a simple original model of the cogging torque mechanism and a Fourier analysis are introduced, and the effects of cog torque elimination on back electromotive force are discussed.
Journal ArticleDOI
Design considerations for fractional-slot winding configurations of synchronous machines
TL;DR: In this article, the authors presented some design considerations for synchronous machines characterized by a fractional number of slots per pole per phase, which is a smooth torque, due to the elimination of periodicity between slots and poles.
Journal ArticleDOI
Rotor Flux-Barrier Design for Torque Ripple Reduction in Synchronous Reluctance and PM-Assisted Synchronous Reluctance Motors
Abstract: The torque produced by a synchronous reluctance machine (including the permanent-magnet-assisted machine) is studied analytically, with the aim of pointing out the effect of the position of the flux barriers on the torque ripple. It is verified that the position of the flux-barrier ends highly influences the torque waveform. With the aim of reducing torque harmonic contents, a new strategy is proposed based on the choice of couples of flux barriers of different shapes. The flux-barrier geometry is chosen so as to obtain a compensation between the torque harmonics produced by each couple. Experimental results on two prototypes confirm the analytical prediction.

Electrical Machine Analysis Using Finite Elements
TL;DR: The Electrical Machine Analysis Using Finite Elements (EMFAE) as discussed by the authors provides tools for the analysis and design of any type of electrical machine by integrating mathematical/numerical techniques with analytical and design methodologies.

Potentials and limits of high speed PM motors
TL;DR: In this paper, the potentials and limits of high-speed permanent-magnet (PM) motors are discussed. And a criteria of optimisation of the motor structure is described, with the diameter ratio and the iron flux density as main design variables.
