This unit introduces various forms of linear and rotary electromechanical energy conversion systems. The basic concepts of electromagnetic theory are revised and applied in the study of voice coil and self-excited linear and rotary actuators. An equivalent circuit model for the complete electromechanical system is developed which provides a basis for subsequent study of dynamic behaviour. The DC machine output characteristics are revised and its operation within a variable speed drive is presented. The operation of power electronic servo amplifiers and phase-controlled rectifiers are also introduced. As an introduction to the AC machine, the concept of the rotating magnetic field is discussed. Subsequent study concentrates on the asynchronous motor where its operation is described, the equivalent circuit is derived and its output characteristics under fixed and variable frequency excitation are analysed.
Having completed this unit, a successful student will be able to:
Large group lectures and small group laboratory-based investigative exercise.
