This paper studies distribution of eddy currents and eddy current losses in the rotor of concentrated winding exterior rotor permanent magnet machines in flywheels. The two-dimension nonlinear transient finite element method (FEM) model including rotor motion was used. Influence of slot opening on the eddy current loss in magnets and rotor back iron is investigated. Segmented magnets for reducing...
Permanent Magnet machines have a high force density and high efficiency. These machines can be made cost effective by using fractional-pitch windings as the fabrication of such windings can be automated. However, one big challenge to design such machines is to analyze the eddy-current losses, specifically in solid back-iron of the rotor/translator and magnets. This paper compares analytical calculation...
