Abstract
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 (W, W, W). 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.
