A novel single-mode linear piezoelectric ultrasonic motor based on asymmetric structure is
proposed. The motor adopts the combination of the first longitudinal vibration and the
asymmetric mechanical structure to produce the oblique movement on the driving foot; then,
the linear output motion is obtained under the friction coupling between the driving foot and
the runner. The motor is designed and its operation principle is illustrated in detail. The
transient analysis is developed to verify the formed movement on the driving foot. A …
