This paper proposes a combined electromagnetic and mechanical topology optimization for weight reduction in electrical machines based on Finite Element Analysis (FEA) Evolutionary Structural Optimization (ESO). The devised method is an on-off-type algorithm with adaptative mesh which low flux density Von Mises stress cells are removed successively from first machine design. With this approach, ...

Superconductor technology has recently attracted increasing attention in power-generation- and electrical-propulsion-related domains, as it provides a solution to the limited power density seen by core component, electrical machines. Superconducting machines, characterized both high efficiency, can effectively reduce size mass compared conventional machine designs. This opens way large-scale pu...

Manufacturing processes such as cutting, welding and shrink fitting are known to degrade the magnetic properties of electrical sheet during manufacturing machines. These effects often neglected at design stage lead large errors in simulated measured core losses machine. This article studies comparative impact different on stator a typical industrial motor. Both simulations measurements indicate...
