PWM Driving Characteristics with Its Self-Locking of Ultrasonic Motor
A traveling wave-type ultrasonic motor (USM) has a self-locking characteristic due to a static frictional force present when its power supply is turned off, because its rotor is pressed strongly to the stator in the USM. We propose a pulse width modulation (PWM) method in consideration of this self-locking characteristic in order to control the motion of USM. The vibration waveform and the driv...
متن کاملExperimental investigation of input–output characteristics of a travelling-wave ultrasonic motor
Speed, position and load characteristics of the ultrasonic motor is considerably influenced from the input characteristics such as driving frequency, magnitude and phase difference of phase voltages. Input and output characteristics of a traveling-wave ultrasonic motor have been investigated from the experimental point of view in the present study. For this aim, a half-bridge serialresonance in...
متن کاملA master-slave system using a multi-DOF ultrasonic motor and its controller designed considering measured and simulated driving characteristics
Master-slave active robot hands and endoscopes, which provide dexterous manipulations and wide views like human hands and eyes, are required to be constructed. We have previously developed a multi-DOF ultrasonic motor consisting of a spherical rotor and a bar-shaped stator. The rotor rotates around three perpendicular axes using three natural vibration modes of the stator. In this study, a mult...
متن کاملReduced Input Throw and High-speed Driving
The U.S. Army is examining new and evolutionary concepts for military vehicles for their future force. In particular, drive-by-wire technology coupled with non-standard driving control devices have the potential to lead to improved driving performance, reduced Soldier training time, crash prevention, smaller vehicle space claims, and improved vehicle safety in military vehicles. However, severa...
متن کاملA High Efficiency Power Supply with High Power Factor Input
This paper presents a single-stage ZVT full-bridge AC/DC converter for aerospace applications. The detailed operating principle and design consideration of this soft-switched converter are analyzed and described. The proposed circuit topology and control scheme are proposed to exhibit optimum performances (i.e. high power factor, high efficiency, ring-free and low EMI features). A laboratory pr...
