Variable speed, permanent magnet synchronous machines with hybrid excitation have attracted much attention due to their flux-control potential. In this paper, a design of axial flux iron poles in the rotor and an additional electrically controlled source fixed on stator is presented. This paper shows results pertaining air-gap control, electromagnetic losses, torque, back emf efficiency maps ob...

The traditional radial flux PMSM and axial have an effective air gap on only one side, between the stator rotor, generates electromagnetic torque. There are defects in magnetic-field utilization, it is difficult to improve torque density. Therefore, this paper proposes axial–radial-flux permanent-magnet synchronous motor (ARF-PMSM), which combines with flux, be used elevator-traction machine-dr...

This paper presents the development of a framework used to optimize and experimentally validate a novel axial flux direct-drive (DD) permanent magnet generator (PMG) for the offshore wind turbine market. This technology aims to offer significant levelized cost of energy (LCoE) reductions via capital expenditure and operating expense (CAPEX and OPEX) savings – a key objective for the offshore in...

Permanent magnet (PM) array affects flux field distribution of electromagnetic linear machines significantly. A novel dual Halbach array is proposed in this paper to enhance flux density in air gap, and thus to improve output performance of linear machines. Magnetic field in three-dimensional (3D) space of a tubular linear machine with dual Halbach array is formulated based on Laplace’s and Poi...

Abstract The article introduces the results of studying magnetic field distribution in alternator inductor with an axial arrangement open cores (OMC) and external closure fluxes. study compares efficiency using fluxes from permanent magnets (PM) on example two model variants inductors OMC developed by authors. analysis density was carried out 3D modelling EMWorks software. It has been shown tha...
