Generators and motors depend on magnetic flux to produce voltage and torque, so they need as much flux as possible. So, they operate near the knee of the magnetization curve (flux not linearly related to the mmf). As magnetizing intensity H increased, the relative permeability first increases ...
OPMENT CORP 3 April 1974 [13 April 1973 12 July 1973] 17943/73 and 33273/73 Heading H2A In a three phase machine utilizing pole amplitude modulation to switch from one speed to another, each phase comprises a number of coil groups spaced at substantially equal angles around the stator, the...
Abstract—Starting with Faraday’s law of electromagnetic induction in 1831, electric (electromagnetic) machines have been developed ever since as “assembles” of electric and magnetic coupled circuits that convert mechanical to electrical energy (in generators) and vice versa (in motors), via ...
59、 Synchronous Machines,with emphasis on torque production in terms of the interactions among its magnetic fields. The purpose of this section is to develop a quantitative theory from which both the electrical and mechanical characteristics of synchronous motors and generators can be determined. The...
