ELCT 130 - Electric Motors and Generators

Credit(s): 2

This course provides a comprehensive overview of DC and AC motor types, application, and control. Operation and construction of DC motors will include series plus shunt and compound types. AC single phase capacitor and split phase start motors plus AC three phase motors are featured. Motor construction of stators, armatures, commutators, and brushes plus motor maintenance and loading effects for optimal operation including DC compounding test is included. Basic motor control troubleshooting principles are discussed in detail, including safe and efficient use of multimeters, high voltage insulation testers, and safe voltage lockout. Students are introduced to solid state and mechanical motor control technology involving relays, silicon control relays, diodes, and solid state motor controllers. Correct safety procedures in compliance with the National Electrical Code® and NFPA 70E® will be emphasized. (Fall Semester)

Course Learning Outcomes: Upon completion of the course, students will be able to

Effectively use ammeters, voltmeters, ohmmeters, and phase detectors in testing and troubleshooting AC and DC motors.
Recognize and use common AC and DC power generation equipment.
Compare and contrast the advantages/disadvantages of three phase and single phase AC motors.
Identify the characteristics of various DC motor types and proper employment of each.
Demonstrate the ability to perform Lockout/Tagout (LOTO) procedures and understand the importance of LOTO.
Demonstrate basic understanding of the principles of motor control and regulation.
Effectively administer NEC® and NFPA 70E® requirements for motor safety.
