ELE 211 - Electrical Machines I (4 CR.)

Course Description

Studies the construction, theory of operations and applications of DC and AC machines. Lecture 3 hours. Laboratory 3 hours. Total 6 hours per week.

General Course Purpose

This course is designed to teach students the basic concepts in electrical machines, such as AC and DC motors, transformers, generators, and pumps. This course will also teach students about major control components used with electrical machines, such as relay and solenoids, frequency drives and PLCs. Students will also learn machine alignment using state-of-the-art mechanical systems trainers.
