High-speed outer rotor synchronous machine
Král, Radek ; Knebl, Ladislav (referee) ; Klíma, Petr (advisor)
The master thesis deals with the construction and design of a high-speed synchronous machine with an outer rotor. The thesis is organised into three main chapters. The first chapter deals with machine design theory as well as mechanical limits, which are significant for high speed machines. This chapter also provides examples of applications of these electrical machines. In the second chapter, the initial design of the machine is calculated analytically. This machine design is optimised and the third chapter of this work shows the results of simulations using the finite elements method, including the evaluation of these results.

Construction of BLDC motor with outer rotor
Smrž, Ondřej ; Vítek, Ondřej (referee) ; Huzlík, Rostislav (advisor)
This work is focused on the construction of the BLDC motor with outer rotor . Its mission is to become familiar with the design, basic relationships, applying this type of motor, the design procedure of magnetic circuit with permanent magnets, and then design the engine. Then there is a verification of designed motor finite element method. Finally, it summarizes the characteristics and parameters of the proposal and will compare the initial design with the other two designs, with some changes in the stator teeth.

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.
