Abstract:
The invention relates to a generator, especially for motor vehicles, which comprises a generator stator (36) having winding slots and subcoils (10 21) lying in said winding slots (35). The subcoils (10 21) are connected to each other via a bridge circuit (3) in order to produce a DC voltage from a multiphase AC voltage produced by a rotary field. The generator is configured as a multiphase generator (30), preferably a three-phase or six-phase generator (30). The aim of the invention is to reduce magnetic nose and torque ripple merely by modifying the subcoil wiring. For this purpose, the subcoils (10 21) are connected to an angular ring and the bridge circuit (3) connected to the ring has a lower phase number than corners of the angular ring circuit (1).
