Reducing Acoustic Noise of Axial‐Gap SRMs by Decreasing Axial Electromagnetic Force Ripple
Electrical Engineering in Japan, 2016 SUMMARYSwitched reluctance (SR) motors are motors that utilize the reluctance torque originating in the magnetic saliency between the stator and the rotor, which are made up of an electromagnetic steel sheet and windings without a permanent magnet. Because of their robustness and simple structure, SR motors are suited for use as the in‐wheel motor for ...

Electromagnetic Force Analysis of Eccentric Axial Flux Permanent Magnet Machines [PDF]
Mathematical Problems in Engineering, 2020 Based on Schwarz–Christoffel mapping, this paper presents a fast analytical method to analyze the electromagnetic force of eccentric axial flux permanent magnet machines, considering static, dynamic, and mixed eccentricities. A quasi-3D model of an axial flux permanent magnet machine is established, and the magnetic field is obtained by Schwarz ...

Radial-axial Force Controlled Electromagnetic Sheet Deep Drawing: Electromagnetic Analysis
Procedia Engineering, 2014 AbstractA new approach, radial-axial force controlled (RAFC) electromagnetic sheet forming (EMF), has been developed for hard-form metal sheet deep drawing. Different to the traditional EMF, an additional radial Lorentz force was introduced at the flange region of workpiece to improve the material flow and reduce the maximum strain of workpiece.
