Credit Hours: 1.5

This laboratory course will provide hands-on experience with motor/generator/transformer circuits and will include the following topics:

transformer turns ratio;
Edison system;
autotransformer;
transformer polarity test and short and open circuit tests;
transformer loading characteristics;
DC generator operating characteristics;
shunt, series, and compound DC motor characteristics;
dynamic braking;
AC three-phase induction motor operating characteristic;
variable speed drives; and
stepper motors.

Course Outcomes
Upon completion of this course, the student will be able to:

develop and identify various types of transformer operations;
determine the characteristics of a practical transformer under loaded and unloaded operations;
relate fundamental laws governing electrical machine operations;
identify the characteristic differences between various DC motors and generator systems;
identify and describe the characteristics of the three-phase induction motor;
use a variable speed control for three-phase motors; and
identify and describe the characteristics of the stepper motor.
