Analysis of Synchronous Machines

All conventional machines rely upon magnetic fields for the purpose of energy conversion. Windings are arranged on the periphery of a stationary member (stator) and a rotating member (rotor) so as to set up a field distribution of magnetic flux density in the space which separates them (air gap). By appropriate excitation of the windings, this field can be made to rotate relative to the stationary member (synchronous machine), relative to the rotating member (DC machine) or relative to both members (induction machine). The interaction of the flux components produced by the stator and rotor members results in the production of torque. Subsequent rotation of the rotor results in electromechanical energy conversion.
