MEC 149 - Electrical Motor Control

4 Credit(s)

Prerequisite(s): MTH 60 or MTH 63 or higher-level math.

Recommended Prerequisite(s): MEC 110 or MFG 210

Course Description: Introduces the fundamentals of electric relay control of AC electric motors found in industrial and commercial manufacturing applications. Students will gain an understanding of the operation, installation, design, and control of AC electric motor control circuits, transformers, ladder logic controls, and control relays for many common applications. Students will also develop skills in interpreting schematics, system design, motor start/stop circuits, and motor sequence control. In addition, students will be introduced to systems troubleshooting, reversing motor controls, automatic input devices and basic timer controls. Students will continue to develop skills in interpreting schematics, system design, motor start/stop circuits, and motor sequence control. Safety is emphasized throughout, highlighting motor safety, lockout/ tagout and safety interlocks.

Course Level: Career/Tech Preparatory
