Experimental Characterization of the Slinky-Laminated Core and Iron Loss Analysis of Electrical Machine

摘要: The manufacturing of the magnetic parts electrical machines requires several industrial processes. These may have effects on properties material, especially in terms iron losses [1]-[3]. With development technique and production machines, slinky lamination method is now being used to significantly reduce material waste [4]. For this process, a long band rolled up spiral way bonded [1]. Thus, stresses (compressive tensile) strain occur simultaneously core. As result, are deteriorated, it hard estimate deteriorated slinky-laminated material. There been studies influence stress [5]-[7]. In these studies, caused by shrink fitting were investigated. Only impact compressive was examined, however, done through test using laminated specimens. This cannot be considered suitable for accurately analyzing loss core machines.
