  • Design studies relating to the brushless doubly-fed automotive alternator

    Creator:
    Ravi, D. K.
    Abstract:
    The alternators in today's automobiles are of the claw-pole or Lundell construction, which is a readily manufactured, low-cost derivative of the conventional rotating dc field synchronous generator. The efficiency of the Lundell system is low due to a complicated magnetic circuit of predominantly solid steel and a high windage rotor...

  • 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...
