EET-219 Electric Motors, Controls, and Variable Speed Drives
Electric motors, controls, and variable speed drives (VSD) provides a review of linear and rotational motion, and energy conversions. The basics of electromagnetism, DC motors and AC single-phase and polyphase motors are studied. NEMA motor classifications A, B, C, and D are explained. Power electronic switches are covered including thyristors and IGBTs. The block diagram of the variable speed drive is studied and the synchronized rectifier stage, DC link, inverter stage, and protective functions are studied. The basic characteristics of PID control are covered and its application to variable speed drives. The variable speed drives offered by various manufacturers including Danfoss, Schneider, an Eaton Cutler-Hammer are contrasted.
