| Abstract | Predmet istraživanja ovog rada je izrada makete uz korištenje frekvencijskog pretvarača Siemens
Micromaster 440 koji upravlja višebrzinskim asinkronim motorom. Maketa je izrađena u svrhu
zamjenjivanja radnog procesa u elektomotornom pogonu. Na početku rada objašnjavaju se
teorijska razmatranja pojedinih dijelova elektromotornih pogona, rada asinkronih motora i rada
frekvencijskog pretvarača. Navode se detaljni opisi metoda upravljanja asinkronim motorom,
kao što je promjena broja pari polova, promjena frekvencije i promjena klizanja. Nadalje dani su
opisi vektorskog i skalarnog upravljanja frekvencijskog pretvarača. Opisani su tehnički podaci i
dan je pregled svih funkcionalnosti korištenog frekvencijskog pretvarača u maketi. Izrađena
maketa je opisana po svim svojim elementima i uređajima koje sadrži. Obavljeno je mjerenje u
programu DASYLab – V 6.00.01 u svrhu dobivanja radnih karakteristika motora. Dan je
pregled svih korištenih parametara i njegovih funkcija za dobivanje željenog radnog procesa.
Cijeli rad je popraćen tablicama, dijagramima, shemama i slikama koje daju cjelokupnu sliku
pravog reguliranog elektromotornog pogona. |

| Parallel abstract (English) | The subject of this graduate work is the production model that consist of frequency converter
Siemens Micromaster 440, which is controls multi – speed induction motor. The model is made
for the purpuse of replacing the work process in the electric drive. At the beginning of this
graduated work the theoretical considerations of individual parts of electric drive, of induction
motor operation and frequency converter operation are explained. There are given detailed
descriptions for methods used for control of induction motor, such as changing the number of
poles, changing frequency and changing slip. Further, there are given descriptions of vector
control and scalar control which is using frequency converter. There are described all the
technical data and given an overview of all functionality of frequency converter. Production
model is described by all elements and devices which it contains. There is done a mesuarement
in program DASYLab – V 6.00.01. in order to obtain the engine perfomance of induction motor.
There are given an overview of all parameters and function to obtain working proces. Whole
graduate work is accompanied by tables, charts, diagrams and pictures that are given an overall
picture of the real regulated electric drives. |
