  2. 2. Faults detection and diagnosis for three phase induction machines

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mohammed Obaid Mustafa; Luleå tekniska universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : Three phase induction motors have been intensively utilized in industrial applications, mainly due to their efficiency and reliability. These motors have good properties such as: increased stability and robustness, durability, large power to weight ratio, low production costs and controllability easiness. READ MORE

  3. 3. Modeling, analysis, state and parameter estimation of faulty induction machines

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mikael Stocks; Luleå tekniska universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : This thesis covers a broad range of subjects pertaining to induction machines, faulty as well as healthy ones. Firstly, a completely new and unconventional methodology for deriving simplest possible, yet sufficiently accurate, mathematical models for induction machines with general electrical faults is presented.
