Near-field acoustic levitation, where planar objects 10 kg in weight can levitate stably near the vibrating plate, is successfully applied both to transporting objects and rotating a rotor without contact. Transporting apparatus and an ultrasonic motor have been fabricated to be measured their characteristics. The theory of near field acoustic levitation both for a piston-like sound source and a flexural vibration source are also briefly described.
