Ultrasonic Motor Using Longitudinal-Torsional Hybrid Vibration,review, LTUMs can be divided into two main types: the first is a multi-mode type, which has the longitudinal and torsional vibrators in the stator. The second one is a mode conversion type, in which only one longitudinal vibration mode is involved, and the torsional vibration can be induced by the l
