Design of direct drive tool turret for CNC lathe
Mrkos, Jan ; Štěpánek, Vojtěch (referee) ; Tůma, Jiří (advisor)
The diploma thesis deals with the design of a direct drive tool turret, which serves as a tool magazine for a CNC lathe. In the introductory part of the work, a research was performed in the field of automatic tool change with a focus on tool turrets and their main structural units. The introductory research is followed by the main part of the work, which begins with the selection of appropriate design solutions, followed by a presentation of the tool turret design created in CAD software Autodesk Inventor 2021 and in the final part of thesis the key elements of the proposed design are verified by calculations.

Crank press 250 with direct drive
Čupr, Pavel ; Pavlík, Jan (referee) ; Omes, Jiří (advisor)
This thesis deals with the design of the single point crank press with direct drive. This crank press has an O-shaped stand and an access to the workspace from two sides. The introductory part of this paper describes the principles of mechanical presses drives, drives arrangement presses with direct drive and some conceptual solution stands. The main part of this work is a calculation of basic drive parameters of the press. There are suggested three design variants. The design with the smallest space requirements and good accessibility to the press working space was chosen. The calculation of the main shaft, the input shaft to the planetary gearing and calculation of brake sizes and the planetary gear to the bend and tough was done. Part of this thesis also includes technical drawing of the assembly press, technical drawing of the drive press, technical drawing of the stand a technical drawing of the satelitte gearwheel.

High-Torque Motors for Battery Operated Material Handling Trucks
Höll, Jan ; Kurka,, Otakar (referee) ; Voženílek, Petr (referee) ; Kuchyňková, Hana (advisor)
he recent development of the power electronic and high-energy permanent magnets enables developing synchronous machines excited by permanent magnets, that are able to meet very gradual and exact control demands. Due to high torque density, that permanent magnet machines reach, the synchronous motors may be used even in direct (gearless) drives. One of the branches, in which direct drives can be used, is material handling. The most propelling drives in this branch consist of induction motor, simple gearbox with invariable gear ratio mounted to the drive wheel. Main aim of this thesis is designing the direct drive motor for low-lift truck. Motor is built-in the driven wheel, therefore outer rotor design appears to be more suitable. Two types of motors – permanent magnet synchronous motor and transverse flux motor have been chosen on the basis of technical paper study, many years lasting experience and verification computations. Both motor types are described in great details in this thesis. Both synchronous motor with PM and transverse flux motor have been designed for direct drive of the given low-lift truck. The proposals of both motors have been optimized by means of finite element method. Based on these design optimizing computations, both motors have been designed, produced and design accuracy has been verified by laboratory testing. Synchronous motor with PM achieves better electromagnetic parameters and its production is also simpler, therefore this motor is more suitable for this application. The solution with transverse flux motor may save substantial amount of active materials. Results of the detailed optimization and comparison of both motor types are the main benefits of this thesis.
