Abstract

The invention concerns a winding for a post or an armature of an electric machine with a post or armature (32) with slots (34) composed at least in part of L-shaped structural parts (1, 2, 3). In doing so, one leg of an L-shaped structural part each time creates a slot bar (8a, 8b) located in a slot, and the other leg creates a connecting line (6a, 6b) located at a face of the post or armature. Moreover, the invention concerns a winding with several interlaced coils (50, 52, 50′, 52′, 50″, 52″) whereby the connecting lines (6) of interlaced coils (50, 52, 52′, 50″, 52″) are staggered and therefore arranged in layers. The invention furthermore concerns a winding with connecting lines (6) flatter than the slot bars (8), styled as a fractional pitched polyphase winding with two slots per pole and branch. The invention also covers a winding consisting of several coils (50, 52, 50′, 52′ 50″, 52″), characterized by the fact that at least two coils (50, 52) are connected in series, whereby the current flows through one coil (50) in the direction of the slot head, and in the other coil (52) in the direction of the slot bottom. The invention also concerns a procedure and a set of structural…
