IEE Electromagnetic Analysis and Comparative Study of AFM OD100
This research presents a comparative analysis of single-sided surface-mounted axial flux permanent magnet (SMAFPM) and consequent-pole axial flux permanent magnet (CPAFPM) machines by evaluating various key electromagnetic parameters. A straightforward replacement of permanent magnets (PMs) with soft magnetic composites (SMCs) is proposed for a conversion of surface-mounted (SM) topology to consequent pole (CP) topology, which maximizes manufacturing ease while sharing the same components. Detailed three-dimensional (3D) finite element analysis (FEA) is performed to assess parameters such as back-EMF, flux-linkage, inductance, torque, and losses. The investigation highlights that despite utilizing 50% less rare-earth permanent magnet (PM) material, the CPAFPM machine produces only 30% less rated torque compared to the SMAFPM machine.

Optimization and Comparative Analysis of Electric Machine Topologies with Varying Magnetic Materials
This research explores the integration of soft magnetic composite (SMC) materials in electric machines, comparing them with traditional laminated steel in various radial magnetic flux electric machine topologies designed for hybrid and electric vehicle traction.
Four distinct electric machine configurations are analyzed: rare earth interior permanent magnet synchronous machines (IPM), wound field synchronous machines (WFSM), spoke ferrite rare earth free permanent magnet synchronous machines (SP- FER), and induction (asynchronous) machines (IM). The benchmark is set by the IPM electric machine originating from a major Original Equipment Manufacturer (OEM), serving as a reference point with volumetric envelope specifications and performance criteria.

Soft Magnetic Composite Application Examples Double Sided Axial Flux Machines
The past decade has seen significant development in the field of soft magnetic composite (SMC) materials and their application in electrical machines. A large part of this can be attributed to their isotropic magnetic properties, allowing for relatively complex structures to support magnetic flux whilst supressing losses.
This document presents a short overview of the SMC technology, from process to powder properties, together with a concept application study. The motor concept is an open-slot, double-sided axial flux machine (DSAFM) with 12 slots and 10 poles, designed to achieve a nominal specification. This concept has been modelled and simulated using JMAG, applying materials manufactured by Hoganas AB that are readily available in the JMAG material database. Details of the electromagnetic design process, model set-up and results are presented.
