Novel ACTFEL phosphor development

Creator:: Ang, Wie Ming
Abstract:: The goal of this thesis is to identify and to explore novel ACTFEL phosphor materials. Several important materials properties relevant to ACTFEL phosphor development are identified. All of these properties cannot be obtained simultaneously. Therefore, several key phosphor materials properties are identified as critical to the development of an ACTFEL...

The Testing of an Alternator

Creator:: Fleser, Russell Harrison and Billings, Everett Monroe
Abstract:: "Before a company which manufactures electrical machines allow them to leave the factory, each must undergo certain tests to make sure that there are no faults of design or workmanship and also ofttimes that they meet the specifications of the buyer. Four important tests are made, e.g. (1) no load...

Design of a Standard Speed, Revolving Field Type, Three Phase Alternator

Creator:: Williams, Floyd J. (Floyd James), 1920- and Rawson, Roy Eugene
Abstract:: The designing of electrical machinery is fully as essential to the thorough understanding of power equipment and apparatus, as is the taking of a laboratory testing course. One learns the relationship of the different parts, the methods of computing their dimensions, and the predetermination of outputs, efficiencies, etc. and thus...

Computerised dynamic control of an ac dynamometer

Creator:: Rodrigues, Terence Keith
Abstract:: The Motor Systems Resource Facility (MSRF) at Oregon State University presently conducts a variety of steady state tests on Motors and Generators, with ratings of upto 300Hp.(225kW), using a dynamometer. The dynamometer consists of an induction motor fed by a power electronic converter. A control computer uses a serial link,...

A low cost AC motor drive for battery powered applications

Creator:: Wiley, Brian
Abstract:: Environmental concerns have renewed the interest in electric vehicles. To gain widespread use, electric vehicles will also have to offer good performance and be reasonably priced. AC drive systems using modern semiconductors can provide efficient operation at the required power levels, but their cost at present is still too high....

Finite element based rotor design optimization for the brushless doubly-fed machine

Creator:: Salim, Mohamed Ali, 1968-
Abstract:: Brushless Doubly-Fed Machines have potential benefits in variable speed generation and adjustable speed drive applications by combining a robust machine structure with a reduced power converter rating. While recent work has demonstrated feasibility, steady-state performance has not been optimized. The nature of doubly-fed operation causes rotor currents of varying, relatively...

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...
