Abstract	A new linear ultrasonic motor using the 1st longitudinal and the 4th bending vibration modes of a bolt-clamped type transducer has been proposed and studied. The new motor with two feet employed only the bending PZT elements. Two groups of PZT elements are clamped between the two exponential shape horns and the flange bolt. The driving feet are located in the same side of the transducer. The working principle of the proposed motor are introduced. After the fabrication of a prototype, its admittance characteristics are measured using an impedance analyzer and the vibration modes are tested by a scanning laser Doppler vibrometer. Finally, the mechanical ability of the prototype is tested.
