## Abstract This paper presents a method of position sensorless control of ultrasonic motors (USM). The position sensorless control method is useful for reducing the cost and size of drive system. The position estimation method is based on the input voltage information of the ultrasonic motor. The

In this paper, heat problem and temperature distribution of a piezoelectric plate-type ultrasonic motor, which is operated at not only steady state conditions but also unsteady state conditions, are analyzed based on finite element analysis and finite difference method. Mechanical vibration losses,
This paper presents an actuator with a sensor for controlling vibrations of machines. It consists of a voice coil-type electromagnetic actuator connected to a piezoelectric sensor and a coil spring. The actuator is used for controlling a motor laid on the beam. The sensor detects the disturbance for
