Motor Principles and Motor Control

Motor Principles and Motor Control 

3 Days Instructor-Led 

2.25 CEUs for Completion

This Motor Principles and Motor Control course is designed for maintenance technicians, industrial electricians, facilities mechanics, and safety supervisors whose work assignments involve installing, maintaining, or troubleshooting 3-phase AC motors and starter logic. This course is 3 days long in total.

This course establishes the essential safety and theoretical foundation for industrial electrical work, focusing on NFPA 70E compliance and the universal logic of Ohm’s Law. Learners will transition from classroom theory to training stations, where they will apply systematic diagnostic methodologies to identify and resolve faults in complex electrical systems. What Each Participant Will Do:

• Execute NFPA 70E Multi-Point Energy Isolation by performing LOTO and 3-Point voltage readings across 3-phase line feeds and control transformers.
  
  
• Wire Dual-Voltage AC Motors by interpreting 9-lead AC nameplates, conducting winding resistance/rotation checks, and configuring high/low-voltage delta and wye connections.
  
  
• Build Starter & Reversing Logic by translating ladder schematics into physical layouts, wiring 2-wire and 3-wire latching logic, and reversing starters with safety interlocks.
  
  
• Apply NEC Article 430 Code Sizing to calculate and select branch circuit conductors (125% FLA), thermal overload relays (115–125% FLA), and short-circuit protection.
  
  
• Troubleshoot Systems using a systematic troubleshooting process with multimeters, megohmmeters, clamp meters, and phase rotation meters to isolate control faults.
