Outline of Final Research Achievements

In this research, we developed a power transfer type ultrasonic motor which drives an object while enlarging micro displacement of the piezoelectric element. A bell crank type mechanism was adopted as a power transmission mechanism, and a plate member was introduced to the contact part with the object. As a result, enlargement in two stages becomes possible. In the experiment, as a result of measuring the basic characteristics of the designed and manufactured stator, the enlargement ratio of the bell crank mechanism for the displacement of piezoelectric element was 1.91 times and the enlargement ratio of the plate member was 3.43 times. Next, as a result of verifying the driving performance, when the drive voltage was 80 V and the preload was 2 N, a rotation number of 366 rpm was obtained for an acrylic material rotor having a diameter of 30 mm.
