ECE 303 Electrical Machines

Rotating electrical machinery are studied with emphasis on the electrical machine as a power delivery component as opposed to a control component. The circuit model viewpoint is used throughout for analytical developments. Dynamic motor-load interactions are derived with the aid of the Laplace transform. Three-phase motor and generator electrical characteristics are studied using circuit models to calculate efficiency, power factor, and regulation. Students will: Predict the mechanical and electrical transients in a motor-load system; calculate the steady-state performance of synchronous motors with the aid of phasor diagrams; calculate the steady-state performance of synchronous generators operating stand-alone and line-connected with the aid of phasor diagrams; calculate the start-up current and the steady-state performance of induction motors.
