Rotor Losses Measurements in an Axial Flux Permanent Magnet Machine

, 2011
MMF space harmonics and slot openings produce considerable rotor losses in permanent magnet (PM) machines, especially if fractional-slot windings are adopted.

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Field model of coreless axial flux machines [PDF]

, 2010
A very interesting construction of disc-type machines are coreless machines. Because there is no core in the stator this type of axial flux machines doesn't have a cogging torque, iron losses or eddy current.

Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

Advanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...

Design Optimization and Comparative Study of Skewed Halbach-Array Magnets TORUS Axial-Flux Permanent Magnet Motors for Electric Vehicles

IEEE Access
The double-sided axial flux (TORUS) permanent magnet (PM) machine has been shown to be an efficient structure for electric vehicles (EVs). This paper introduces the combined techniques of skewed PMs and Halbach-array arrangement to improve the TORUS-type

An Explicit Constitutive Reconstruction Framework for Mechanical Characterization of Miniaturized 3D‐Printed Specimens

Advanced Engineering Materials, EarlyView.
An explicit constitutive reconstruction framework enables accurate tensile characterization of miniaturized additively manufactured specimens using only the grip‐to‐grip displacement measurements. Progressive validation through self‐consistency, analytical comparison, and inverse finite element method (iFEM) benchmarking demonstrates constitutive ...

Iron Loss Analysis of Stator Claw‐Pole Electric‐Excitation Field‐Modulation Machine Considering Three‐Dimensional Flux Density Distribution

IET Electric Power Applications
By incorporating the advantages of magnetic gearing effect and claw pole structure, a new type of claw‐pole electric‐excitation field‐modulation (CPEEFM) machine has been developed, which has potential direct‐drive application prospects due to its ...

Discrepancies Between Micro Versus Macroscale Viscoelastic Properties in a Microplastic‐Tissue Composite Model

Advanced Engineering Materials, EarlyView.
This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.

Design of axial-flux permanent-magnet low-speed machines and performance comparison between radial-flux and axial-flux machines [PDF]

, 2005
This thesis presents an alternative approach to the analytical design of surface-mounted axialflux permanent-magnet machines. Emphasis has been placed on the design of axial-flux machines with a one-rotor-two-stators configuration.
