PURPOSE:To drive a plurality of loads simultaneously with the direct coupling of a motor, by driving a plurality of output shafts separately by vibration generating sources, which are independent with each other. CONSTITUTION:A motor is constituted of an elastic body 1, made of rubber, first and second stators or first and second annular disc type vibrating bodies 2, 3, first and second rotors, having first and second output shafts 4a, 5a integrally, or disc type first and second rotary bodies 4, 5 and bearings 6. The elastic body 1 is the vibration damping body of a vibrating body 3 and becomes a supporting body. The vibrating bodies 2, 3 are constituted of a vibrating sheet, an electrode, a piezo-electric element and the like respectively. When predetermined alternative voltages are impressed on the piezo-electric elements respectively from alternative power sources under above described constitution, traveling wave vibrations are generated and rotary bodies 4, 5 are rotated. As a result, the output shafts 4a, 5a are rotated and respective loads, coupled with the output shafts 4a, 5a, may be driven simultaneously. |
