Simulation of synchronous generator at insular operation
Kořistka, Petr ; Ondrůšek, Čestmír (referee) ; Huzlík, Rostislav (advisor)
This work deals with a creation of model of synchronous generator in programmes such as Simplorer and Maxwell, and also its operation in an insular operation. In the paper are described Maxwells equations for solving electromagnetic field, theory of synchronous machine, further are briefly described a simulation programmes which were used. In the next part of work is described production of geometric model of generator and its later electromagnetic analysis in the Maxwell programmes environment. For a simulation of generators operation in insular operation were chosen 2 cases. The first case simulates an operation of generator at the step change of residence of R-L load, the second simulation an automatic regulation of voltage at the step change of residence of R-L load. The simulations were running in the Simplorer programme and at link simulation Maxwell Simplorer programmes.
Design of synchronous spoke motor
Kopecký, Jan ; Bulín, Tomáš (referee) ; Knebl, Ladislav (advisor)
This thesis is focused mainly on the theoretical research of permanent magnet synchronous motors. In addition, various methods of designing the motor‘s magnetic circuit are discussed and their advantages and disadvantages are compared. The reluctance network method is analyzed more thorough, because this method is used for motor designing process. In the last part the results obtained by reluctance network are compared with the results evaluated by finite element method.
Complex simulation model of vibration power generator
Harapát, Jan ; Ondrůšek, Čestmír (referee) ; Hadaš, Zdeněk (advisor)
This work is focusing on analysis of current development in energy harvesting projects in aerospace industry field, and on analysis of current development in vibration generator field. It is also concentrating on establishment of a complex simulation model of vibration generator. It deals with modeling of magnetic field of generator and its cross connection with a mechanic and an electronic model.
Drive of peristaltic pump for medicine
Smrž, Ondřej ; Procházka, Petr (referee) ; Huzlík, Rostislav (advisor)
This work is focused on the design of the peristaltic pump drive for medical purposes. Its initial goal is closer introduction of peristaltic pumps and stepper motors. Then the design of BLDC motor will be made and the use of this motor will be compared with stepper motor. Design of the BLDC motor will be made using RMxprt. Last but not least simulations of both types of motors for the peristaltic pump will be created in Simplorer. Finally, the program LabVIEW will be introduced and a program for controlling a stepper motor will be created.
Stator Windings Currents Analysis Of The Ipm Machine Under Short-Circuit Conditions
Knebl, Ladislav
The development of the synchronous motors with permanent magnets is, mostly thanks to the legislation pressure to achieve the highest efficiency in electric drives, experiencing raising interest. Since the number of motors used in the industry is growing year by year, it is reasonable to investigate the motor behavior under faulty conditions, such as short-circuit conditions. This paper deals with the stator current analysis of interior permanent magnet synchronous motor under the short-circuit condition, both short-circuit in one phase and symmetrical three-phase short-circuit.
