Stator for an electric machine and electric machines

The invention relates to an electronically commutated electric machine (1), comprising: - a circular-cylindrical stator (2) having spaced stator teeth (22), wherein a part of the stator teeth (22) of stator coils are surrounded as a single tooth windings, so that formed in any of between the stator teeth (22) of stator slots (23) more than one coil side (31) a stator coil (3) is located; has a rotor (4) relative to the stator (2) is rotatably mounted and, by surface mounted permanent magnets (41) formed rotor poles (42) -; wherein the stator coils (3) are divided into several groups, which are connected via separate star points.
