ABSTRACT:
A device for starting an engine and generating power comprising a frame attached to a main body of an engine, a stator core fixed in the frame and attached with a stator coil, a field core attached to an inner end face of the frame, having a clearance in the radial direction between the field core and an inner peripheral portion of the stator core and accommodating a field coil, a claw-pole type rotating field electrodes disposed between the stator core and the field core interposing air-gaps respectively among the field electrodes, the stator core and the field core, a driving shaft passing through an inner diameter portion of the field core and supported thereby through bearings, a planetary gear device interposed between a crankshaft and the driving shaft an end portion of which is fixed with a sun gear which decelerates and transmits first rotation of the driving shaft to the crankshaft in starting an engine and accelerates and transmits second rotation of the crankshaft to the driving shaft in generating power, a transmission supporting body attached to an end portion of the driving shaft, provided with a plurality of blades for serving as a fan on an outer end face thereof and attached with and supporting the rotating field electrodes, and a front cover attached to a front portion of the frame, surrounding the transmission supporting body and provided with intake openings for a cooling wind at an outer end portion thereof.
