Motor and Motor Controls

This course is an application of common electrical concepts and relay ladder logic/motor control circuits used in industry to maintain and troubleshoot electrical power and control systems, including variable frequency drive systems. Students will learn how to install, operate, maintain, and troubleshoot single-phase transformers, NEMA and IEC contactors & motor starters, motor branch circuits, and reversing circuits (power & control). A heavy focus of the course will be on variable frequency drives. Students will learn to install, maintain, program and troubleshoot industrial programmable VFDs. The course will focus on 3 types of VFD: Automation Direct’s GS2, Allen Bradley PowerFlex 70 and Allen Bradley PowerFlex 525. After completing this course the student will: 1. Install and troubleshoot single phase transformers. 2. Explain, calculate and measure power distribution voltages 3. Explain and troubleshoot NEMA and IEC contactors and motor starters 4. Install and troubleshoot three phase motor branch circuit. 5. Install and troubleshoot three phase motor reversing circuits. 6. Explain the basic operation of a programmable variable frequency drive 7. Wire and configure a programmable variable frequency drive 8. Program and troubleshoot a variable frequency drive 9. Configure and interface a VFD to an AB CompactLogix PLC 10. Explain the signal/data flow in a PLC based system to control a VFD
