PCT No. PCT/JP88/00128 Sec. 371 Date Oct. 6, 1988 Sec. 102(e) Date Oct. 6, 1988 PCT Filed Feb. 9, 1988 PCT Pub. No. WO88/06370 PCT Pub. Date Aug. 25, 1988.In the present invention, a clutch plate is attached to a crankshaft; revolving-field poles are fixed on this clutch plate; and a magnetic gap is provided between the outer peripheral section of a pair of field cores which hold field coils, and the inner peripheral section of the revolving-field poles. Since a clutch plate material suitable for the accomplishment of clutch function can be selected, it is possible to improve the reliability of the clutch and to avoid giving a heat effect to the revolving-field poles. Furthermore, decreasing the size and weight of the fixed magnetic field can reduce parts cost as well as assembly cost.
