The purpose of this course is to let students possess the ability of the dynamic modeling and simulation for electric machinery. The contents of the course include the reference-frame transformation theory, modeling of synchronous machines, simulations of synchronous machines, modeling of induction machines, simulations of induction machines, modeling of DC machines, simulations of DC machines. The aim is to let students understand the steady-state mathematical model and dynamic model of various motor, principle of motor driver and principle of variable speed control. The drivers include phase-controlled rectifier and chopper of DC motor, inverter of AC motor. Moreover, let students understand the scalar control and vector control principle of AC motor.
