Abstract (en)

[origin: WO2015110246A2] The invention relates to an electric motor (8), which is equipped with a commutator disk (26), which has contact zones (27) for electrically and mechanically contacting corresponding contact elements (29). A simplified construction results if one of the contact zones (27) is designed as an annular positive-pole zone (32), while one of the contact elements (29) is designed as a positive-pole contact (34), which is in contact with the positive-pole zone (32) and which is electrically connected to a positive-pole connection (35) of the electric motor (8), if one of the contact zones (27) is designed as an annular negative-pole zone (30), while one of the contact elements (29) is designed as a negative-pole contact (31), which is in contact with the negative-pole zone (30) and which is electrically connected to a negative-pole connection (32) of the electric motor (8), if at least one of the contact zones (27) is designed as an annular control zone (36), which is segmented in the circumferential direction (33) into positive-pole segments (38), which are electrically connected to the positive-pole zone (32), and negative-pole segments (39), which are electrically connected to the negative-pole zone (30), and if, for each coil (23), one of the contact elements (29) is designed as a coil contact (37), which is in contact with the particular control zone (36) and which is electrically connected to such a coil (23).
