Abstract
Normal flux distribution along the rolling directions at joints of overlapped stacked electrical laminations is investigated to set up a flux distribution similar to that in the zip-type unicore. A 2D model of a C-core and three layers of overlapped laminations with joints with similar characterisitics to a zip-type unicore were formed and an FE analysis was carried out to solve the problem using a static magnetic analysis and unidirectional vector potential formulation. The results show that when the reluctance changes in the closed magnetic paths causes the flux deviates towards shorter magnetic paths moving to adjacent layers increasing the magnetic flux density. This redistribution causes the flux to transfer easier at joints in the unicore compared to other jointed cores.
