Abstract

A layer of laminations for a shell- type transformer core comprises an E lamination providing three legs 1, 2, 3 and a yoke 5. and an I lamination providing a yoke 4, the width c1 of the yoke 5 being greater than the width c2 of the yoke 4. The width b of the outer legs is greater than half the width f of the middle leg, and the sum c1 + c2 is greater than f. In the stacked core the E and I laminations may be in respective stacks, or alternate layers may be reversed (Figs. 2 and 3 not shown). The laminations may be secured by cementing, welding, or clamping. The arrangement permits nearly wasteless stamping. <IMAGE>
