Abstract
Presently, study and application of a multi-DOF ultrasonic motor (USM) in the world are in investigating stage, many structural types of multi-DOF USM occur. A multi-DOF USM based on a vibrator with single longitudinal-bending transducer was proposed and studied. The transducer brings the multi-DOF driving trajectories only with single tip. The tip drives a spherical spinner. Modal analysis was carried out for a cross orthogonal transducer with the FEM method, the longitudinal and bending resonance frequencies were degenerated. An analytical model of the multi-DOF driving foot trajectories was developed, the driving foot trajectories with typical driving forms were analyzed with numerical simulations. Relationships of rotary speed versus voltage and torque versus rotary speed around three coordinate axes were measured in tests, the corresponding efficiency was figured out. The experimental results were coincident with trajectories of analysis.
