The aim of this diploma thesis is the design of machine for sheet metal cutting. This machine uses laser beam divide the material. The work is focused on the increase of the aesthetic character the machine has., at the same time the work include an ergonomic improvement, which make the operation more efficient and facile.

This diploma thesis deals with design of rotor of synchronous reluctance machines. There is a theoretical description of rotor geometry of synchronous reluctance machine that respects natural flow of magnetic flux inside complete rotor. The parametric model of rotor is made with usage of ANSYS Maxwell and Matlab software. Furthermore, the parameters of the machines are confirmed using the same program. Finally, changes of motor parameters are observed in connection with different rotor geometries.

The topic of this work is the design of a vertical lathe with a table diameter of 2,500 mm. Part of the work is the analysis of current products in order to solve their shortcomings. The result is an innovative design focused on user-friendly operation and progressive shaping. At the same time, the designed machine fulfils all technical, ergonomic and aesthetic requirements.

The topic of this thesis is the design of a testing device for checking electrical car sockets according customers’ requirements. The electrical socket shall be tested by electrical, mechanical and camera tests. The diploma thesis is divided into two main parts, first is a part describing the basic elements in the construction of electric vehicles, and describing types of electric sockets in electric vehicles, and second, a practical part describing the design of a testing device.

This thesis focuses on design of small testing machine for measuring tensile strength of materials. Appropriate hardware for driving the motor with serial communication will be used. Main drive is a stepper motor with microstepping. Instructions for motor is provided by microcontroler which will be comunicating with aplication in computer. This aplication will have all user functions nessesary for using this device.

The task of this thesis is a design and a construction of a semi-automatic single-purpose machine. This machine is designed for testing seven types of wiring harnesses, which are going to be tested, whether they contain all needed parts. The machine also measures some parts of the harnesses. It is necessary to use more types of sensors in the design and the construction of the single-purpose machine. All controlling and measuring processes are automatic. An operator of the machine just inserts the wiring harness into a fixture, activates the program, then removes controled harness and puts it into the right box. The task of this thesis is solved in a cooperation with Mechatronic Design & Solutions s.r.o. company.

The aim of this diploma thesis is to design a single-purpose machine for machining steering wheel lever from PUR. The problem with the current state was the need of manpower for machine a large number of levers. The automated machining process eliminates the problem. The result of the work is a detailed 3D model of a single-purpose machine created in the Onshape program, drawing documentation of several parts of the equipment, economic evaluation and risk analysis of the machine. The conclusion of the thesis contains an evaluation of the whole project.

This thesis is dealing with thermal fields and the possibilities of their solution by a finite element method. Thereinafter thesis describe assembling a 3D model of induction machine with known parameters, and solving thermal field of the model by Ansys Workbench program and verification of these results by practical measuring on real machine.

Automatic cutting machine can cut wires and cables to user-defined length at a specified number of pieces. These equipments are usually custom-made for needs of the requested application and they are not very spread out tools on the Czech market. This described device is specified for efficiency-rise in the production of heat-resistant cables. These prepared cables are used for internal connection of the resistors.

The aim of this master´s thesis was to model the fan for the induction motor, and then to solve this model using Ansys CFX in the terms of flow, when considering the different speeds of rotation of the rotor. The introduction of this work is dedicated to basic terms and definitions from spheres of fluid flow, cooling of the electrical machines, especially to the cooling of the asynchronous machine. There is also attention paid to losses in this machine. Finally, there is modeled radial fan and an air gap of specified induction machine. By using Ansys CFX the flow, which passes from the fan into the air gap, is analyzed.
