Title: (EN) ELECTRIC MACHINE
Abstract:
(EN) The present subject matter relates to an electric machine (10), in particular an alternating current generator. The electric machine (10) includes a rotor (20) having a rotating axis direction. The rotor (10) is configured as a claw-pole rotor and includes two claw pole plates (22, 23) with claw pole fingers (24, 25) disposed at their external periphery. The rotor (10) further includes a coil carrier (60) disposed between the two claw-pole plates (22, 23). The coil carrier (60) holds an exciter winding (51) having two connecting conductors (66), each of which is connected in an electrically conducting manner to a power supply element fastened to the rotor (20). The coil carrier (60) includes a wall (78) with an attachment section (81) extending from the wall (78). Further, one of the connecting conductors (66) is wound around the attachment section (81) and the attachment section (81). The attachment section (81) includes undercuts (87), facing away from another, at an end (84) of the attachment section (81) facing away from the wall (78). The attachment section (81) has a cross sectional area (93) that is oriented perpendicular to a winding direction of the connecting conductor (66) around the attachment section (81). The winding direction is oriented in the rotating axis direction of the rotor (20).
