Abstract
The theories of a new type of linear ultrasonic stepping motor's drive and self-correcting positioning were discussed. The forced progress of an elastic body slider on a stationary steel beam was analyzed. The expression of the restoring force of the slider at the motor's self-correcting stage was given. These theories have been examined by means of experiment. The calculated result was basically consistent with the experimental one.
