  • Analysis of brushless doubly-fed, stand-alone generator systems

    Creator:
    Gorti, Bhanuprasad V.
    Abstract:
    This thesis introduces a Brushless Doubly-Fed Machine (BDFM), stand-alone generator system. Development of a BDFM current-forced model, along with the analysis of air gap power distribution between the two stator windings and the rotor circuit, pave the way for the characterization and analysis of stand-alone generator systems. The main disadvantage...

  • Performance Test of an Induction Motor

    Creator:
    Bowman, Harry David and Cady, Harry Palmer
    Abstract:
    The induction motor in its electromagnetic features is essentially a transformer, while in its general behavior it is analogous to the continuous-current shunt wound motor. In a transformer the primary and secondary members are both stationary and electrical energy is transformed from one pressure to another by the ratio of...

  • The Design of an Induction Motor, Single Phase Double Current Generator Set

    Creator:
    Stutz, Lester Eugene and Pernot, Fred Eugene
    Abstract:
    Throughout the year the regular design work of the class room proved so profitable that it was thought that there was no subject which could be selected for thesis purposes of greater benefit,or which offered as great a latitude in the working out of the various problems, than the one...

    Buchanan, Elmer Clarence and Smith, Arthur Byron
    Abstract:
    The following discussion is confined mostly to that type of machine in which the squirrel care revolving secondary it used. In its most primitive form it con - listed simply of a disk- aramature as described by Baily in 1870 and due to Tesla (1888), of the fact that two,...

  • The Induction Motor

    Creator:
    Taber, Howard Weston and Spires, Fred Lloyd
    Abstract:
    The problem of the economical transmission of power has long been a serious one to the engineer. Formerly the power had to be generated on or near the spot where it was to be used, but now the advance that has been made in Electrical Engineering has largely done away...

  • Theory and Construction of an Induction Motor

    Creator:
    Chapin, Norris Everard and Christiansen, Clarence Lewis
    Abstract:
    In order that the proper motor for a given service may be chosen it becomes necessary to study and know the requirements and characteristics of the machine which may be used for that purpose. When these are known the selection of that one which is best adapted for the use...

  • Direct digital speed control system for a DC motor using a minicomputer

    Creator:
    Evans, Donald LeRoy
    Abstract:
    Direct digital control is becoming quite common in the control of industrial processes. However, due to the relatively high accuracy of both analog and conventional digital systems for controlling the speed of a dc motor, there has been a reluctance to try DDC for this purpose. This thesis describes a...

  • Frequency-domain, parameter estimation for a brushless, doubly-fed machine

    Creator:
    Ramchandran, Ashok
    Abstract:
    A Brushless, Doubly Fed Machine (BDFM) attempts to combine the advantages of conventional induction and synchronous types of electrical machines by its unique architecture. The validation of BDFM designs in an actual test environment requires the estimation of the BDFM model parameters from actual experimentation. Accurate values for the parameters...

    Abstract:
    A relatively new development in the electric machines field has been the written-pole technology, of which the latest product is the large single-phase electric motor, the single phase Written-Pole Motor (WPM). The WPM is a synchronous, permanent-magnet single-phase motor having a weak rotor cage for start-up which in addition exhibits...
