PURPOSE:To improve the strength and durability and to reduce the weight by rotatably vibrating a disc-shaped induction plate by a drive coil and an exciting magnet, and operating the plate as an armature. CONSTITUTION:An exciting magnet 1 is composed of a pair of right and left magnet halves 1A, 1B. A pair of drive coils 5 are formed of a plurality of ring- shaped coils 6.... A disc-shaped induction plate 7 made of copper or aluminum is rotatably supported between the halves 1A and 1B. The plate 7 is rotatably vibrated by the induction current generated by the current flowed to the coil 5 and a magnetic flux generated between the halves 1A and 1B of the magnet 1, and the plate 7 is operated as an armature. |
