摘要： The invention relates to a double-phase rotating field machine having a 2p-pole stator with winding teeth (Z), which is designed with a winding arrangement in tooth coil technology, comprising two phase windings (W1, W2, W3), wherein the winding arrangement is formed from wound coil groups (G) with coils nested in one another several times, wherein the coil sections (T) of said coil groups (G) are arranged concentrically surrounding one another from the inside to the outside, and comprise two or a plurality of winding teeth (Z), wherein the respective coil winding numbers are arranged in the grooves (N) between the winding teeth (Z) such that in each case an essentially uniform coating of each groove (N) with the same effective total conductor cross section of the coils per groove cross section is given.

摘要： A 3-strand rotating field machine with a 2p-pole stator with winding teeth (Z), formed with a winding arrangement in tooth coil technology, has three winding strands (W1, W2, W3). The winding arrangement is formed from wound coil groups (G) with coils that are multiply interleaved. The partial coils (T) of the coil groups (G) are arranged so they concentrically enclose one another from inside to outside and surround two or more winding teeth (Z). The respective coil winding numbers in the grooves (N) between the winding teeth (Z) are provided. Thus, in each case a substantially equal occupancy of each groove (N) is provided with the same effective total conductor cross section of the coils per groove cross section.

摘要： 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).
