Title: Ultrasonic motor
Inventor: KUWABARA SHIGEO
IPC: H02N2/00
Filed: 1993-07-29
Abstract: PURPOSE:To obtain a high performance ultrasonic motor having long service life by a constitution wherein a drive unit, constructed to produce a uniform fastening pressure on the surface abutting a piezoelectric element, is pressed resiliently against a rotating drum and born rotatably thereat. CONSTITUTION:A piezoelectric element 1a is arranged, at the opposite ends thereof, with an inertial body 1b and a driving body 1c. Flanges extend from the opposite sides and bolts 1d are tightened thereat to integrate them while imparting a required surface pressure thus constituting a drive unit 1. When attaining clockwise rotation, power is fed from a clockwise pulse power supply to synthesize a counterclockwise elliptical wave motion at the pressed lower surface part A thus driving a rotary drum 2 with the frictional force induced from the wave motion. When the bolts 1d are tightened, each flange part is bent in the direction of the tightening force but the flexure is relaxed at the groove part and the tightening force of bolt 1d is imparted as a uniform surface pressure. This structure realizes an ultrasonic motor having high performance, stabilized driving characteristics, and long service life.
