Mathematical model of synchronous motor width permanent magnet
Fajkus, Petr ; Klíma, Bohumil (referee) ; Huták, Petr (advisor)
The work is focused on the design of synchronous motor control with field weakening possibility. At present synchronous motors used in many applications. Often is used synchronous motor with permanent magnets. This type of motor may have different transverse and axial inductance. In most cases it is desirable to design the engine using a computer model. Therefore the synchronous motor described mathematically in order to create the model of motor. At work is also crated model of synchronous motor control. The control is designed for the highest possible speed range. Therefore, the motor control is consist of two parts. Speed is controlled by voltage in the first part. In the second part speed is controlled by field weakening. Everything is created and simulated in a computer program MATLAB-SIMULINK.

Model of synchronous motor
Petruška, Ľubomír ; Zbranek, Pavel (referee) ; Veselý, Libor (advisor)
Activity, construction and mathematical model of the synchronous motor with modeling and simulation in Matlab Simulink are the main topics of this project. Attention is mostly oriented to synchronous motors with permanent magnets (PMSM) for their using in servo drives. Using voltage equations of motor, Clark and Park Transforms with mechanical equations, equations in state-space form was derived. Principle vector control was also derived from phasor diagram. This knowledge was modeled and simulated in Simulink.

Simulation models of electric drive vehicles
Bílý, Lukáš ; Huzlík, Rostislav (referee) ; Havlíková, Marie (advisor)
The work deals with creating a DC electric motor drive. The model is composed of electrical power from the engine model and transistor pulse converter load, which are joined together and completed the anchor and regulate the flow control engine speed. Great attention was paid to the determination of losses in the load drive electric vehicles and create a model of electric power load. The real work was verified by an experimental model of an electric vehicle Car4 the available parameters.

PMSM Drive Sliding Mode Control
Koňarik, Roman ; Blaha, Petr (referee) ; Václavek, Pavel (advisor)
The goal of this diploma work is to design a control for permanent magnet synchronous motor in sliding mode. The introduction describes a synchronous motor, sensors which are used in the control process as well as power devices. Further, there is description of mathematical model for the synchronous motor. Another part of the diploma work deals with classic vector control for this kind of motor followed by the sliding mode control for the motor. At the end, there is presented an algorithm which has been implemented in the processor designed for this equipment. All the controllers used in the equipment have been tested on motor simulations. In conclusion, there is a target analysis and facts finding.

Design of interior permanent magnet synchronous motor
Žák, Ondřej ; Mach, Martin (referee) ; Vítek, Ondřej (advisor)
The thesis describes problematics of synchronous motor with permanent magnets. The design is provided by analytic and empiric procedures. The great accent is placed on the description of the magnetic circuit of the motor. The finite element method analysis of designed motor is performed subsequently. The main target of this thesis is to find the way, how the ferrite permanent magnet should be used in synchronous motor.

Design of cooling of electrical machines for production machines and systems
Vaněrková, Tereza ; Vlach, Radek (referee) ; Huzlík, Rostislav (advisor)
The aim of this thesis is to design the water-cooling system for a synchronous motor with an output of 10kW. The power loss was analytically determinated. For the initial water-cooling system and for two design proposals, thermal models were calculated in Ansys. The same boundary conditions were set for all three models. Then the analysis results of the temperature distribution on the machine surface and in the slots were compared. The comparison also includes the economical cost of the production and service of the machine. Then the production documentation was created, consisting of the assembly drawings and a simplified technological process.
