متن کاملA Novel Rotary Piezoelectric Motor Using First Bending Hybrid Transducers
We report a novel rotary piezoelectric motor using bending transducers in this work. Three transducers are used to drive a disk-shaped rotor together by the elliptical movements of their driving tips; these motions are produced by the hybrid of two first bending vibration modes. The proposed piezoelectric transducer has a simple structure as it only contains an aluminum alloy beam and four piec...
متن کاملPositioning Control of a Novel Thin-Disc Ultrasonic Motor using Fuzzy Sliding-Mode Control
The thin-disc piezoceramic-driving ultrasonic actuator dedicated to a stepping ultrasonic motor is proposed. The mechanical hysteresis and dead-zone phenomena are automatically compensated by a closed loop servo control, i.e. Fuzzy Sliding-Mode Control (FSMC), for position tracking. The controller design of FSMC has syncretized the fuzzy reasoning and sliding mode control with robust stability ...
متن کاملVibration Torque Measurement and Mechanism Analysis of Rotary Stepping Motor
Vibration torque are existence obviously during operation of stepping motor, it is a periodic structure vibration problem. In this paper, the actual vibration torque testing of stepper motor is executed through a selfmade vibration torque sensor, the experimental results show that the stepping motor vibration torque of single three shot operation is more bigger than the six shot, and obvious re...
متن کاملDesign and Fabrication of a Longitudinal-Torsional Ultrasonic Transducer
A hybrid longitudinal-torsional ultrasonic transducer is designed and fabricated in this research. The design of the transducer was performed using the FE method with ABAQUS software, with the aim of combining the longitudinal and torsional vibration modes. The transducer horn is then fabricated using a 4-axis milling machine. The PZT stacks are employed in order to excite the transducer. The t...
