Experimental measurements and theoretical analyses of a novel non-contact ultrasonic motor driven by near-field acoustic levitation are presented, in which the proposed motor is comprised of a Langevin transducer, stator disk and rotor disk. In exciting of Langevin transducer, the air layer between...
