Abstract:
The invention relates to a six-pole DC machine, particularly a DC motor for use in a motor vehicle, having a stator (16) excited preferably by a permanent magnet and a rotor (20) which is rotatably supported in a pole housing (12) and which has a wave winding (23) and a commutator (24), and having a brush carrier (28) for holding the brushes (26) and preferably additional components (30, 31; 32). In contrast to a full equipping, the brush arrangement has less than six brushes (26), which are arranged on the circumference of the commutator (24) at an angular distance of approximately 60° to each other. Thus, the ripple of the rotor current, the torque oscillations, and the noise emission are clearly reduced and free space is created on the brush carrier for accommodating suppressor components (30, 31; 32).
