Abstract

Reduction of the size and weight of a hybrid transducer type ultrasonic motor without increase of the resonance frequency was accomplished by using a flexural vibrator in place of a driving vibrator. The contact parts of the transducer were fabricated so that they achieved a line contact condition to a guide rail. The maximum speed and maximum outputforce were 47 cm/s and 140 gf.
