Abstract

See full text

A coil with a distributed winding formed from hairpins that each have two straight-line conductor portions arranged in different slots of a coil body. Contact regions shaped in circumferential direction adjoin the conductor portions at one axial end and are connected at the other axial end through a turning region. The contact regions have at the end remote of the coil body a connection portion that are aligned in radially extending rows. The contact regions of a layer are shaped in the same circumferential direction. A portion of the contact regions of an outer layer is deformed in radial direction to form an additional, and these contact regions are shaped in a circumferential direction opposite to the contact regions of the outer layer.
