    Design and Implementation of Drive and Control System for Ultrasonic Motor over Power Line Communication
    (Taylor & Francis Inc, 2024) Daldal, Nihat; Aytar, Oktay; Bekiroglu, Erdal; Bal, Gungor
    In this study, remote control application of an ultrasonic motor (USM) has been achieved over the power line communication (PLC) system. Fast, practical, affordable and effective operating mode is essential for the USM. This study aimed to develop an original, efficient, effective and economical method. Drive and control of USM control has been succeeded with the developed PLC control system. A two-phase high-frequency inverter, a power line transmitter, and a power line receiver circuits have been designed to drive and control of the ultrasonic motor. Required measurements are acquired from the power line to select the most suitable communication frequency and coupling circuit impedance for the PLC system. For the communication frequency and impedance value measurements the receiver and the transmitter circuits have been designed. The PLC-controlled system has been tested for different operating conditions of the ultrasonic motor. USM control has been accomplished over the existing power line without using extra cables and interfaces for communication. The obtained results show that the PLC-controlled system is practical, reliable, cost-effective, and feasible for the remote control of the USM. This research contributes a new and essential perspective for the PLC-based remote control studies in addition to the USM drive and control strategies.

    PC Based Control and Monitoring of Travelling Wave Ultrasonic Motor
    (Gazi Univ, 2006) Bal, Gungor; Bekiroglu, Erdal; Bayindir, Ramazan; Gorgun, Alper
    In this study, speed control of a traveling wave ultrasonic motor has been implemented with microcontroller and has been visualized on the computer screen. Digitally controlled a drive system has been developed to control the motor. Speed/position data have been taken from 500 rpm incremental encoder mounted on motor shaft. Comparators circuits having high frequency operating capability have been designed to measure frequency, voltage and phase difference. A PIC 16F877 microcontroller has been used to provide connection and transmission between computer and ultrasonic motor drive system. Also it is used to evaluation of processed data. An interface software developed by using Visual Basic 6.0 to provide visual control and monitoring features. Load and varying operating condition responses of the motor have been examined experimentally. Also actual measured values and values estimated from the system have been compared. Elastic control has been provided with computer aided automation in the study. As an advantage the study can be used for educational purpose by this feature. It is revealed that the microcontroller controlled and computer based monitoring system give effective solution to the travelling-wave ultrasonic motor.
