Stator assembly

An electronically commutated DC motor having

• a stator assembly with a plurality of stator poles (31-36), said plurality being divisible by six,
• a first (31), a second (32), a third (33), a fourth (34), a fifth (35) and a sixth (36) of said stator poles being arranged successively within a predetermined angular range;
• three winding phases (70, 72, 74) connected in a delta configuration;
• three respective current rails (U, V, W, 38, 40, 42) associated with respective ones of said winding phases for their connection
• wherein
• a first winding coil (51) is arranged on said first stator pole (31) and electrically connected between a first one (38) of said current rails and a second one (40) of said current rails;
• a second winding coil (52) is arranged on said second stator pole (32) and electrically connected between said second current rail (40) of said current rails and a third one (42) of said current rails;
• a third winding coil (53) is arranged on said third stator pole (33) and electrically connected between said third current rail (42) and said first current rail (38);
• a fourth winding coil (54) is arranged on said fourth stator pole (34) and electrically connected between said first current rail (38) and said second current rail (40);
• a fifth winding coil (55) is arranged on said fifth stator pole (35) and electrically connected between said second current rail (40) and said third current rail (42);
• and
• a sixth winding coil (56) is arranged on said sixth stator pole (36) and electrically connected between said third current rail (42) and said first current rail (38);
• wherein at least two successive winding coils (51, 52) are continuously wound and at their interface (61) are electrically connected to an associated current rail (40) without interrupting their winding wire (44);
• and
• a permanent magnet rotor (22), wherein said stator assembly (20) has three stator poles for each pole pair of said rotor (22).
