  1. 1. Contributions to the electromechanics of unbalanced magnetic pull in a synchronous hydropower generator

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Yogeshwarsing Calleecharan; Luleå tekniska universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Misalignment between the rotor geometrical axis and the geometrical stator axis in a hydropower generator is usually present at standstill and when the machine is under operation. Now, rotor-stator eccentricity in a rotating electrical machine is a harbinger to abnormal operating conditions of the machine. READ MORE

  2. 2. On the dynamics of an hydropower generator subjected to unbalanced magnetic pull : characterisation and analysis

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Yogeshwarsing Calleecharan; Luleå tekniska universitet.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Eccentricity leading to unbalanced magnetic pull (UMP) in rotating electrical machines is a significant concern in industry. The UMP arises due to magnetic flux crossing the air-gap between the rotor and stator, and can be more intense than the useful peripheral force that the machine develops. READ MORE
