This course in electromechanical devices is one of 16 courses in the Energy Technology Series developed for an Energy Conservation-and-Use Technology curriculum. Intended for use in two-year postsecondary institutions to prepare technicians for employment, the courses are also useful in industry for updating employees in company-sponsored training programs. Comprised of seven modules, the course is designed to provide a working knowledge of control elements in electrical circuits, transformers, motors, and generators. Topics presented include switches, circuit breakers, relays, fuses, transformers, d.c. and a.c. motors, and generators. Written by a technical expert and approved by industry representatives, each module contains the following elements: introduction, prerequisites, objectives, subject matter, exercises, laboratory materials, laboratory procedures (experiment section for hands-on portion), data tables (included in most basic courses to help students learn to collect or organize data), references, and glossary. Module titles are Electromechanical Devices--An Introduction, Control Elements in Electrical Circuits, Transformers, Generators and Alternators, D.C. Motors and Controls, A.C. Motors and Controls, and Synchromechanisms. (YLB)
