Abstract:
The invention relates to a stator for an electric motor comprising several poles (P) that are directed inwards towards the motor axis (2) and that surround a rotor (1), each pole (P) being provided with one winding (L) and the coils of the windings (L) being wound around the poles (P) one after the other without interruption. The stator (20) contains at least three pole groups (n), having at least three poles (P) and each group having the same number of poles (P). The windings (L) run out from the end face at least at the respective beginning and end of a pole group and are contacted there in such a way that the windings (L) associated with each pole group contain their own connection pair (U-U′, V-V′, W-W′) and one connection (U′, V′, W′) of each of these connection pairs is connected to a star point (Y) on the end face of the stator (20). The windings (L) are wound around the poles (P) one after the other with an alternating winding direction (WR), a single pole (P) having a winding (L) with the same winding direction as the preceding winding (L) of the preceding pole group (n) at an individual transition point between two pole groups (n).
