Two groups of identical upper and lower rotating arms may be respectively fixed at the places 100 and 515 mm in height of the center shaft, each group including 6 rotating arms each having an length of 390 mm. A.sub.M is fixed by the bottom plate P and the frame, and the base of A.sub.M is a magnetic suspension bearing. The lower rotating arm is fixed at a place 100 mm in height of A.sub.M, and the ring-shaped magnet M.sub.A is fixed onto the lower rotating arm; and

    [0105] the magnetic conductive plate around which the conducting wire twines and the nylon plate A are fixed onto the bottom plate P in a mode of being parallel to the magnet M.sub.A and aligned with the perimeter. The distance between the lower surface of the nylon plate A and the upper surface of M.sub.A is 5 mm.

    [0106] The magnet M.sub.B and the upper rotating arm are fixed together, and then the center lines of the two coincide. The upper rotating arm onto which the magnet M.sub.B is fixed is fixed at a place 515 mm in height of A.sub.M. The distance between the lower surface of M.sub.B and the upper surface of the nylon plate B is 5 mm.

    [0107] The two ends of the conducting wire are respectively connected to the wiring posts 1, 2.

    [0108] A.sub.M is driven to rotate by power, and DC electromotive force is generated between the wiring posts 1, 2. If the angular velocity of A.sub.M is 60 revolutions per minute, the DC electromotive force is 39 volt.
