Abstract
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.
