In this article, performance of 70 W, 350 rpm, axial-field and radial-field permanent magnet brushless dc motors is compared using computer aided design sCADd and finite element sFEd methods. The design variables like number of poles, slots per pole per phase, airgap length, airgap flux density, slot electric loading, stator flux density, and the permanent magnet material are changed one at a t...
This paper presents a thermal model of an axial flux permanent magnet synchronous motor (AFPMSM) with the structure of double-stator single-rotor called an axial-flux interior-rotor (AFIR) permanent magnet synchronous machine. The proposed 3D model involves formulation of the heat conduction equations of 3D model using finite element technique. The model considers most of the complexities of th...
This paper presents the design, analysis, and prototyping of a novel axial-flux permanent-magnet (AFPM) motor capable of auto-starting. The preliminary design is a slot-less double-sided solid-rotor line-start AFPM motor with 4 poles for high torque density and stable rotation. One spaced raised ring was added to the inner radii of the rotor disc for smooth line-start motor. The design allows t...

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...
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...
