A STUDY GUIDE TO DC MOTOR CONTROLS
Trainees who complete this program will be able to: - identify and explain the operation of several types of DC motors; - explain how an solid state DC controllerl regulates the speed of a DC motor; - explain the basic operation of a phase-controlled rectifier bridge and a DC chopper; - explain the different ways in which braking may be achieved in a solid state DC controll system; - describe conditions in solid state DC motor control systems which may lead to operating problems, then recommend and implement procedures that may prevent the problems from occurring or recurring.
