摘要：The invention relates to an electric machine comprising a claw-pole rotor,particularly an electrically excited, at least 12-pole claw-pole machine (10) for a motorvehicle. The stator (16) of the machine, the winding of which has multiple phase windingsand is connected to a rectifier arrangement (69) or alternatively to a pulse-controlledinverter arrangement using the phase winding connections (80 to 84) of said winding, hasan inner diameter (Di) that is smaller than the associated outer diameter (Da) of themachine by a factor of 0.70 to 0.77, preferably by a factor of 0.73 to 0.75, at least in thegroove center. According to the invention, the ratio of the groove widths (Bn2) at thegroove openings (37) to the groove widths (Bn1) at the respective groove base (36) lies inthe range of 0.69 to 0.81, preferably in the range of 0.73 to 0.78.
