RECORDING THE CHARACTERISTICS OF A DC MOTOR

Tematika ovog rada temeljena je na proučavanju i ispitivanju rada istosmjernog motora čemu je prethodila izrada makete te postavljanje svih elemenata sustava. Rad je osmišljen na način da se odredi brzina okretaja motora preko optičkog enkodera ili nekim drugim načinom. Obzirom da motor sadrži i pripadni tahogenerator, njega će se uzeti za određivanje broja okretaja osovine. Opterećenje je vršeno preko remenice, a sve povezano s dinamom koji se često nalazi na biciklima za dobivanje određenog napona. Uz to, potrebno je odrediti i pripadne struje te padove napona na motoru. Svi ti podaci, bili oni digitalni (s enkodera) ili analogni (s tahogeneratora), bit će usmjereni u instalirani mikrokontroler naziva USB 6009 OEM koji je ujedno i dio National Instruments grupacije. Na kraju se podaci prebacuju u program LabVIEW koji će biti korišten za simulaciju i vizualizaciju dobivenih podataka.The topic of this task is based on the study and testing of the operation of a DC motor, which was preceded by the creation of a model and the installation of all elements of the system. The operation is designed in such a way as to determine the speed of the motor via an optical encoder or in some other way. Since the engine also contains an associated tachogenerator, it will be taken to determine the speed of the shaft. The load was done via a pulley, all connected to a dynamo that is often found on bicycles to obtain a certain voltage. In addition, it is necessary to determine the associated currents and voltage drops on the motor. All this data, whether digital (from the encoder) or analog (from the tachogenerator), will be directed to an installed micro controller called USB 6009 OEM, which is also part of the National Instruments Group. Eventually the data is transferred to the LabVIEW program which will be used to simulate and visualize the obtained data
