A Novel Cylinder Driving Ultrasonic Motor


Article Preview

The paper presents a novel structure cylinder driving USM (ultrasonic motor). Through development and experimentation, the torque and rotational speed of the prototype were tested, which proves that this type of USM has a very simple structure, self-adjusting pre-tightening force and compensation for wear. The results verify the theoretical feasibility and provide instructions for the industrialization of this type of USM.
