Abstract
A three-phase machine with a 2-pole stator (10) formed with a winding arrangement of a double-layer tooth-wound coil winding has m winding phases (U, V, W). The winding arrangement has at least one first double-layer tooth-wound coil (20) and one second double-layer tooth-wound coil (30). Each tooth-wound coil occupies a half of each of four respective adjacent slots (N) of the stator (10) with a winding phase (W). Each double-layer tooth-wound coil (20, 30) forms two concentrically arranged coils. The second double-layer tooth-wound coil (30) is arranged such that it is shifted by a pole pitch with respect to the first double-layer tooth-wound coil (20).
