Abstract (en)
[origin: WO2009068609A1] An electrical drive machine having a stator (35) and a rotor (38), wherein said rotor (38) carries a rotor winding (49) in grooves (46), which can be supplied with electrical current via a power supply system made of a commutator (52) and sliding contacts (58), wherein said sliding contacts (58), which press on a surface of said commutator (52), have at least two pairs made of one positive sliding contact (581) and one negative sliding contact (582) each, wherein said positive sliding contact (581) and said negative sliding contact (582) oppose one another at an angle ? which deviates by 180° in at least a first pair of one positive sliding contact (581) and one negative sliding contact (582).
