ULTRASONIC MOTOR AND MANUFACTURE OF ULTRASONIC MOTOR

摘要

PROBLEM TO BE SOLVED: To remove the fear of the electric continuity pattern of an ultrasonic motor lead substrate being peeled off the main body of ultrasonic motor lead board. SOLUTION: The ultrasonic motor support member 124 of an ultrasonic motor 130 is fixed to an ultrasonic motor shaft 132. A piezoelectric element 802 is fixed to an ultrasonic stator body 122b. An ultrasonic motor 122 is fixed to the ultrasonic motor shaft 132. An ultrasonic motor lead substrate 136 is fixed to the rear of the ultrasonic motor supporting member 124. The tip 136e of an electric continuity pattern 136a and the tip 136f of the electric continuity pattern 136b are welded severally to the electrode of a piezoelectric element. This ultrasonic motor is provided with an ultrasonic motor 134 rotatably to the ultrasonic motor shaft 132. The ultrasonic rotor 134 is brought into pressure contact with the ultrasonic stator 122 by a pressurizing spring 138.
