... optimization design. Design/methodology/approach First, this paper presents a universal analytical model for slotless Halbach array permanent magnet ( PM ) synchronous motor and derives the air-gap flux density and back electromotive force (back-EMF). Second, the influence of pole pairs, PM thickness...

...He Cheng; Fandi Lin; Jing Wu; Tong Zhang Purpose The purpose of this paper is to introduce and analyze a dual-side-permanent-magnet Halbach array vernier (DSPMHV) machine and to propose methods for achieving high torque density. Design/methodology/approach Flux harmonics and torque...

... is a prerequisite for pre-design and optimization. Design/methodology/approach This paper proposes an analytical model of permanent magnet machines with segmented Halbach array (SHA-PMMs) to predict the magnetic field distribution and electromagnetic performance. The field problem is divided into four...

... torque on air-gaps was obtained by Maxwell stress tensor. In order to simulate the movement of both rotors in relation to the winding and modulators two movement bands were applied. Findings It was proved that the MGFIG magnetized with Halbach arrays is able to eliminate the cogging torque, improve...

...Murat Caner; Chris Gerada; Greg Asher; Tolga Özer Purpose The purpose of this paper is to investigate Halbach array effects in surface mounted permanent magnet machine (SMPM) in terms of both self-sensing and torque capabilities. A comparison between a conventional SMPM, which has radially...
