Patent ID: 8350438

Claim:
Stator for an electronically commutated electric motor with a cylindrical stator jacket ( 20 a ) and a multiplicity of poles (P) of ferromagnetic material directed inwardly toward the motor axis ( 2 ), wherein the poles (P) encompass a cylindrical hollow volume for receiving a rotor ( 1 ) and wherein each pole (P) is provided with one winding (L) each with a multiplicity of wire turns for the implementation of a magnetic armature, wherein the turns of the windings (L) are disposed wound successively without interruption about poles (P) and that the stator ( 20 ) comprises at least three pole groups (n), each with the same number of poles (P) and at least 3 poles (P) each, and these are disposed sequentially at the circumference of the stator ( 20 ) distributed circularly, wherein the windings (L) are carried out at the end side at least at each beginning and end of a pole group and here are at least partially cut open and are contacted here such that the associated windings (L) to each pole group, which forms a phase, comprise their own terminal point pair (U-U′, V-V′, W-W′) and that from each of these terminal pairs the one terminal (U′, V′, W′) is connected at the end side on stator ( 20 ) to form a star point (Y), characterized in that the windings (L) at the poles (P) successively are wound with alternating sense of winding (WR), wherein a single pole (P) at a sole transition between two pole groups (n) bears a winding (L) with the same sense of winding as the preceding last winding (L) of the preceding pole group (n), wherein the total number of poles is odd and corresponds to a multiple of the number of phases, and including sensors disposed in the end side region of the other half of the circumference of the stator ( 20 ), facing away from the phase lead-outs (U, V, W) and the star point connection (Y).
