| Abstract [eng] |
The aim of this study was to investigate a novel burst type signal generator for controlling an ultrasonic motor (USM). For this purpose, an experimental burst type signal generator consisting of a shock exciter, a waveguide, a Langevin-type piezoelectric transducer and backing mass was designed and investigated. The proposed burst type signal generator allows to control a USM in stepper motion, rendering traditional signal generators and power supplies superfluous. The investigated burst type signal generator is designed for controlling a USM with a 20.2 kHz resonant frequency and allows to generate a burst type electric signal with the same frequency. In view of the fact that such a harvester does not require traditional power supply, it could be used as an impact energy harvester. Also, a simple scheme for improving shock exciter operation using an additional capacitor was proposed and investigated. Such a scheme allows to drive USM up to 30 steps instead of 1 per one electric charge of the additional capacitor. |
