Precision and dynamics of linear piezo motors
Ilichman, Ondřej ; Vaške, František (referee) ; Houška, Pavel (advisor)
The work deals with the design, control, precision and dynamics of linear piezoelectric motors from PiezoMotor Uppsala AB. The aim of this thesis is to evaluate the applicability of the loaned engine in a mass spectrometer. In introduction‘s section of this work is discussing the design principles of functionality, materials used, procedure and types of piezoelectric motors. It focuses the choice of hardware and design of mechanical assemblies, which could replace the current mechanism with electromagnetic motors. Then we designed and fabricated a test report with hired piezoelectric motor. In NI LabView development environment is created test application for control and measurement. The final section is devoted to a summary of the positive and negative features of the hired piezoelectric motor and evaluation of accuracy and dynamics.

Electric microdrive with ultrasonic motor
Peřina, Martin ; Feiler, Zdeněk (referee) ; Koláčný, Josef (advisor)
This thesis is focused on selected kinds of piezoengines and their ability to control and follows the separate semester project. It mainly deals with technnology called Piezo LEGS and Piezowaves. Attention is paid to their structure, principles, parameters, characteristics, but also to field of their application. Next section is laboratory measurement of those species of piezoengines (demo-kits). At the end thesis contains three laboratory task, each type of engine is dedicated toone task. The contents of the work is focused on innovation activities in the learning process.

Proposal of Microactuator Based on SMART Material
Hradil, Aleš ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
The master’s thesis deals with the proposal of microactuator based on SMART material. The thesis opens with the comparison of SMART materials which are suitable for actuator construction from the point of view of a reaction on stimulation in form of deformation. Subsequent part of the thesis is the report theory of piezoelectric effect, it also describes direct and indirect effects and it concerns about the description of piezoelectric materials. The thesis focuses on several principles of piezoactuators and motors. The last part of the thesis includes modeling and simulation of piezoelectric material in program ANSYS 13.0 and dimensioning geometric of actuator with evaluation of impact of parameters on final motion.
