PURPOSE:To transmit energy efficiently, by covering the salient section of a crank-shaft with a closed cover of non-magnetic thin substance, by providing a permanent magnet for a rotor inside the comer and an electromagnetic coil for a rotor outside the cover. CONSTITUTION:An inner rotor 12 is fixed on the salient section 1' of a crank- shaft 1, and on the circumferential face of the rotor, a plurality of a pair of permanent magnets 14 are fixed so that the polaritites may be alternately arranged. The inner rotor 12 is covered with a closed cover 6 having a non- magnetic thin section 7. An outer rotor 18 having a plurality of electromagnetic coils 20 is formed outside the closed cover 6. Distances G1, G2 between the thin section 7 and the permanent magnet 14 and between coils 20 are made shorter, and the magnets 14 are magnetically combined with the coils 20. On starting, the outer rotor 18 is clamped with a clamp 25, and alternating current is made to flow to the coils 20, and the inner rotor 12 is rotated. The clamp 25 is taken out, and DC voltage is applied to the coils 20. Then, on starting of engines as not shown in the figure, the outer rotor 18 is fixed by the clamp 25, and an induced electromotive force is obtained from the outer rotor 18. In this manner, energy is efficiently transmitted. |
