This paper examines the torque ripple and cogging-torque variation in permanent-magnet
synchronous motors (PMSMs). The effect of slot number and magnet skewing on …

Slotted axial-flux machines have excellent power and torque densities. However, it is difficult
to reduce their cogging torque due to the complexity associated with implementing classical …

A subdomain model considering the influence of tooth-tips is developed for predicting the
armature reaction field in surface-mounted permanent-magnet machines having either non …

The main focus of this paper is cost-effective techniques to reduce the cogging torque in
permanent magnet (PM) wind generators. However, there are also certain limits with which …

The paper discusses the guidelines for designing concentrated winding fractional slot
permanent magnet machines. The winding factor and different slot and pole combinations …

This paper addresses the torque production and losses of concentrated winding permanent
magnet motors. These synchronous motors having either semi-closed slots or open slots …

This paper examines torque ripple, cogging torque, and radial forces in permanent magnet
synchronous motors (PMSMs). Effect of slot number on electromagnetic torque (including …

A surface-mounted permanent magnet (SPM) machine is widely used in many auxiliary
parts of an electric vehicle, so its design level directly influences the performance of the …

The influence of various types of windings on the cogging torque and the total torque
developed by a three-phase permanent magnet synchronous motor (PMSM) is investigated …
