Rotor fault diagnosis of induction motors
Bednařík, Václav ; Cipín, Radoslav (referee) ; Vítek, Ondřej (advisor)
This bachelor thesis focus on the faults of induction motors. In general terms to mechanical and electirc faults and their influence on induction motor. Further on the tests, that are conducted on induction motors to detect faults and states that precede them. Main part is devoted to rotor eccentricity and broken rotor bars. Eccentricity is solved within theoretical analysis and measurements on free damaged motors. As well as broken rotor bars, which are supplemented by measurements on three damaged rotors. There are two types of eccentricity, static and dynamic. Faults of broken rotor bars is solved in terms of postion of broken rotor bars and their number.
