Zusammenfassung: | The invention relates to an electronically commutated direct current motor having an inner rotor and a three-phase stator (1), which has a closed return ring (32), a plurality of inwardly directed stator terminal (33) in one piece with the latter, and an insulating material body (4), which covers the stator terminal (33) by means of terminal covers (21) and the return ring (32) by means of a return ring cover (19), and the insulating material body (4) has a wire guiding means (5) projecting axially parallel from the return ring, (19), which are interrupted by wire leadthroughs (8), wherein n stator terminals (33) are provided and each stator terminal (33) is wound with a coil (S1 to S9). The problem addressed by the invention is ensuring a compact design having low axial and radial dimensions, optimal efficiency even when a needle winding method is used, and the ability to be produced simply in a direct current motor of the generic type. This problem is solved, according to the invention, by claims 1 and 17. |
