Abstract

PURPOSE:To obtain a high torque and high durability, by using an elastic body, bonded to a cylindrical piezo-electric body, as a stator. CONSTITUTION:A cylindrical piezo-electric body 1 is bonded to the inner surface 36 of a cylindrical fixed base plate 35 and an AC power source is conducted to it through electrodes 2, 3. An elastic body 4 is a thin metal and is bonded to the inner surface of said piezo-electric body 1 to constitute a stator 1a. A rotor 5a, consisting of blocks 5 and a cylindrical body 6, is equipped at the inside of the stator 1a while the outer cylindrical surface of the cylindrical body 6 is provided with recessed and projected configuration and the blocks 5, divided into a plurality of segments, are inserted into the recessed part of the cylindrical body 6. Said elastic body 4 repeats traveling elastic wave motion, generated by the AC power source, impressed on the cylindrical piezo-electric body 1 through the electrodes 2, 3, and a rotating force, about a rotary shaft at the center A of the blocks 5, is generated whereby the rotor 5a is rotated with a high torque.
