3-Phase Motor Basics


Training duration: 1 day

This one-day class is designed for individuals who are already familiar with the concepts covered in our Basic Industrial Electricity class and want to further their training in this field. Attending Basic Industrial Electricity Is not a prerequisite for attending this class, but it is recommended. This class will cover 3-phase motors in more detail than Basic Industrial Electricity. Motor construction, nameplate data, and principles of operations will be discussed, as well as terminal markings, electrical connections, and enclosures styles. Participants will learn how to properly size overloads, fuses, and circuit breakers to protect motors. Students will learn the common causes of failure for electric motors and the steps necessary in troubleshooting. PLCs will also be introduced and discussed in the context of their application to maintenance personnel. This class will be a good introduction for participants with little knowledge of PLCs. General operations and basic troubleshooting procedures will also be discussed. The material covered in this class is practical and is designed to make an immediate positive impact on your maintenance department.
