  • Use of multiple loop model for brushless doubly fed machine rotor design

    Creator:
    Kemp, Alson R.
    Abstract:
    The Brushless Doubly Fed Machine (BDFM) is receiving attention as a candidate for use in adjustable speed drives (ASDs) and variable speed generators (VSGs). With a large percentage of a drive or generator system's cost due to power electronics content, considerable research has been conducted to find drives in which...

  • Testing and modeling of the single-phase Written-Pole Motor

    Creator:
    Chis, Lucian
    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...

  • Performance and parameter prediction of large synchronous machines from physical dimensions

    Creator:
    Heberle, David D.
    Abstract:
    A project funded by the Southern California Edison (SCE) Company, Research Center of Irwindale, California, has supported the development of a performance and parameter prediction software program for use during the refurbishment of large synchronous machines, turbine generators, and synchronous condensers. The computer program was developed for SCE to allow...

  • Preliminary studies on a magnetic elevator for solids (MES)

    Creator:
    Ranawake, Udaya A.
    Abstract:
    The thesis describes the preliminary studies on a laboratory model of a magnetic elevator intended as part of a system for circulating magnetic materials in chemical reactors. A multiple coil laboratory model, controlled by computer, was designed and constructed. Current measuring transducers were used to monitor system performance and study...

  • General pole number model for the brushless doubly-fed machine

    Creator:
    Boger, Michael S.
    Abstract:
    The Brush less Doubly-Fed Machine (BDFM) has the potential to be a more cost effective replacement for conventional induction or synchronous machine drives. The BDFM has two stator windings: a power winding and a control winding. An electronic power converter of variable voltage and frequency is connected to the control...

  • Design procedure for brushless doubly-fed machine used as a limited speed-range pump drive

    Creator:
    Alajmi, Abdulhadi M.
    Abstract:
    The continuing desire of industry to further improve process efficiency, through tighter control and energy conservation, has prompted users to pay closer attention to Adjustable Speed Drives (ASDs). The conventional ASDs consist of induction or synchronous motors controlled by power electronic controllers through the adjustment of supply frequency and line...

  • Passively controlled variable-speed generator system

    Creator:
    Bathon, Tobias Siegfried
    Abstract:
    This thesis presents both an analysis and simulations of a passively controlled variable-speed generator system, which can be applied for renewable energy sources such as wind turbines. Parallel connected passive/external resistors and inductors are connected to the slip rings of a wound rotor induction machine to provide an acceptable speed...

  • Development of a 300 Hp regenerative motor and generator test facility

    Creator:
    Lewis, Timothy M. (Timothy Michael)
    Abstract:
    A 300 hp motor and generator testing facility is being completed at Oregon State University. The testing center is the largest independent testing facility west of the Mississippi River. This regional resource center will incorporate state-of-the-art features that set it apart from other testing facilities. An induction machine with a...

  • Three-dimensional finite element design procedure for the brushless doubly fed machine

    Creator:
    Thompson, Brenda E.
    Abstract:
    Brushless Doubly Fed Machines (BDFM) have potential advantages in variable speed generation and adjustable speed drive applications. The most significant of these advantages is a reduction in the power electronic converter rating, and therefore a reduction in overall system cost. Presently, efforts are being directed at optimizing the design of...
