A key observation in the study of ultrasonic motors is that the peak vibration that may be induced in structures occurs at a relatively constant vibration velocity regardless of frequency. The vibration velocity is simply the time derivative of the vibration displacement in a structure, and is not (directly) related to the speed of the wave propagation within a structure. of Comm.

These are electric motors, which produce motion by the mechanical vibration of the stator, placed against the rotor (for rotation) or the slider (for linear displacement). The operation principle of the motor is analyzed by the finite element simulation, and then, the motor prototype is designed and manufactured. A coupled linear ultrasonic motor (LUSM) based on an eccentric constraint was proposed. two surfaces on the projection oppose two surfaces on the groove to prevent movement in a side direction orthogonal to a movement direction of the elastic member relative to the rail, where the movement direction is the same as the longitudinal direction and the side direction is orthogonal to the heightwise direction. Ultrasonic motors are broadly classified into travelling-wave types and standing-wave types. The operate sequence of (1)-(2)-(3)-(4)-(1) enables the motor to drive the upper and lower sliders of dual sliders to move along the positive direction of the X-axis synchronously. Different from the traditional linear ultrasonic motors, The proposed motor mainly contains a stator and dual sliders. For these experiments, the preload was set to 8 N and the excitation voltage was 200V. The motor proposed in this paper can be compared with others designed in recent years. Piezoelectric motors. The combined slider can achieve a larger output, but it cannot reach the sum of upper sliders output and lower sliders output. X. Yang, Y. Liu, W. Chen, and J.
