Design of permanent magnet synchronous motors
Bureš, Petr ; Cipín, Radoslav (referee) ; Vítek, Ondřej (advisor)
Given today’s trend with environment being very important, there has been an ongoing attempt in the rotating machine industry to create machines with highest efficiency possible. And so, permanent magnet synchronous machines represent types of machine with very high efficiency and are gradually replacing other machines in many applications. This work deals with familiarization of the properties of permanent magnet synchronous motor as well as typical design choices. The main focus of this work is the design of permanent magnet EC motor and following comparison of results obtained from analytical design and analysis in the RMxprt program. Finally, the results of design methods are compared.

Construction of educational model "Ball on Stick"
Coufal, Ondřej ; Formánek, Martin (referee) ; Dobossy, Barnabás (advisor)
The goal of this thesis was to create an educational model, which could be used as a demonstration of dynamic model and its regulation for future students of mechatronics. The construction was inspired by a similar construction but with much smaller dimensions where most of components were printed by a 3D printer. Afterwards there was created an electrical scheme and implemented on a printed circuit board. For the whole system was designed a caskade regulation, that makes sure the ball will reach the desired position, which is adjustable.

MIL real time simulation of electrical motors
Bartík, Ondřej ; Veselý, Libor (referee) ; Blaha, Petr (advisor)
The goal of this thesis is how to implement the two different types of the electric alternate motors in ZYNQ-7000 device for MIL real-time simulation purposes. The chosen types of motors are BLDC motor and AC induction motor. Mathematics models of these motor, the necessary changes for implementation purposes and the way how the models were implemented in ZYNQ-7000 device are described in this work. Three different experimental MIL simulation, using these motors ae described at the end of this thesis.

IP core for BLDC motor control
Hráček, Marek ; Bohrn, Marek (referee) ; Dvořák, Vojtěch (advisor)
This diploma thesis is about using vector control (or field-oriented control) of synchronous BLDC and PMSM motors on FPGAs. First part describes basic theory of these motors and how to control them. Then vector control is detailed and its parts as (or Clarke) and Park transformation. Rest of the thesis deals with the design of universal controller with adjustable accuracy in VHDL language. Data is separated from computing part which utilizes custom arithmetic-logic unit. In the last part of the thesis the design is tested in simulator using model of PMSM motor.

Aircraft Flight Controls Actuator - Modeling and Control
Kolář, Bohumil ; Kopečný, Lukáš (referee) ; Pohl, Lukáš (advisor)
The aim of this bachelor thesis is to compile and control the actuator model, which approximates the behavior of a real actuator under load. The work describes individual types of actuators and their properties. The mathematical model of the actuator is also described. This model consists of a motor and a load. The mathematical model is applied in the Simulink environment where a control structure was designed and added. The work also describes the construction of the real actuator and its subsequent testing in the ControlDesk. The results of the individual test are in the form of step responses.

Compact inverter for BLDC motor
Nevřivý, Tomáš ; Červinka, Dalibor (referee) ; Procházka, Petr (advisor)
The work describes the design and implementation of compact inverter for brushless DC motor, which have mechanical power 600 W and rated torque 1.6 Nm. Motor is designed for DC link voltage with value 300 V. The focus is placed on the cost and simplicity. On this basis, the inverter is designed for uses single purpose power and control circuit. The power part is solved using a circuit FSBB15CH60C. The circuit is placed on a separate board of power electronics. Cooling of the power circuit is performed by the surface structure of BLDC motor. Control of the inverter ensures circuits LB11696V and NE566. The both circuits are placed on separate board of control electronics. Circuit LB11696V contains a control algorithm, as well as protections, which are necessary for safe operation of the inverter. Power supply of electronics is performed using step-down converter from MYRRA company.

Remote-controlled cross-country four-wheeler
Kejzlar, Radim ; Novák, Lukáš (referee) ; Háze, Jiří (advisor)
The bachelor's thesis focuses on the complete design and implementation of an RC vehicle controlled by a smart device with the OS Android using Bluetooth communication. The RC four-wheeler is designed in accordance with the requirements of the BUT FEKT interactive gaming room, where this vehicle is intended. The work deals with the electrical, the program and mechanical part. The electrical part includes a complete selection and description of the drive, implemented using a BLDC motor and its controller. The controller is controlled by a control unit in the form of a microcontroller from the AVR family, which also processes the received data from Bluetooth communication. The design also includes a suitable selection of the Li-Pol technology battery and its capacity. The program part deals with the development of an application for the Android OS using the Mit App Inventor 2 development platform, and in the mechanical part the chassis used for the RC four-wheeler and the design solution of the entire design are discussed.

Universal BLDC motor controller
Pijáček, Ondřej ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
This thesis describes the design of universal control unit for BLDC motor powered from airplane power distribution system of 28 V capable of driving motor up to 10 A. The maximal engine power is about 250 W. Important prerequisite is possibility of driving various motor size without needs of changing wiring board using only the configuration in the auxiliary memory unit. To control different motors is enough one unit with one program without any way to interfere to the unit itself.
