摘要：
A new concept of a vibrators alternation stepping ultrasonic motor, based on longitudinal vibrations of rectangular Langevin resonators, is presented. The new motor fed by a single- phase resource without feedback is capable of bi- directions step displacements without accumulative displacement error. The step angle is 1.44 degrees, when the 150 grooves on the rotor are used in positioning. The average rotation speed without load in one step is 16.49 - 14.65 rad/ s, and the braking torque is 0.071 - 0.088 Nm in operating frequency 30 kHz and operation voltage 200 V. (c) 2006 Elsevier B.
