EMT Training

The Snell Group is a leader in Electric Motor Testing (EMT) using portable, computer-supported test equipment to monitor and trend the condition of electric motors and supporting circuitry to reveal a wide-range of hidden problems. Read about our certification program.

Our team of Snell Electric Motor Testing experts has decades of experience in EMT training and consulting, starting with some of the earliest test methods, including low resistance bridges, oscilloscopes, megohmmeters and many more. EMT has evolved to the point where it needs to be an integral part of a company’s asset management program.

Taking an electric motor testing class is an essential part of a company’s ability to create and maintain a successful condition monitoring/PdM program. EMT courses are available in multiple formats to meet the wide ranging needs of our customers seeking continuous professional development, including:

  • Customized on-site EMT classes at your facility using your own tester.
  • EMT training courses at public locations around the world.
  • An electric motor testing class that addresses your EMT certification needs.
  • Information sharing through newsletters, tips, white papers, and online forums.

Taking an electric motor testing training will qualify the technician to gather and interpret data, which will bring a greater return on investment in your motor program. Electric motor testing classes consist of online (energized/dynamic) testing as well as offline (de-energized/static) testing.

The following motor circuit analysis classes are offered by The Snell Group. Please see our EMT Course Schedule for a list of available dates and times.

On-site Training
All EMT training courses listed below can be customized to meet your exact needs and specific applications and conducted at your location. There are many advantages to hosting an on-site training class, including:

  • A lower total training cost for groups with six or more participants.
  • The ability to integrate hands-on field work with your facility's motors.
  • A lower student to teacher ratio, maximizing the attendees learning experience.

1-EMTTS–Electrical Theory Basics
Online Course—On-Demand
The ability to successfully use motor test instruments will be dependent upon your knowledge of basic electrical theory. The first several hours of this course is “theory review.” It is not only important to understand relationships between voltage, current and resistance, it is also important to understand the characteristics of different circuits and how they affect collected data. In this group of modules, you will review DC and AC theory at a level that will provide you the necessary background to effectively test electric motors both de-energized and energized. This topic in conjunction with the rest of the course will enable anyone that successfully completes this course to become a highly effective motor test technician.

2-EMTTS–Electric Motor Fundamentals
Online Course—On-Demand
In this section we will continue to build the foundation, necessary, for you to be highly successful at diagnosing motor and motor circuit problems. We will explore differing distribution and grounding systems and how they may impact data collection and analysis. We will also explore how motors are constructed. Without understanding the design and construction of motors, it is quite easy to misdiagnose any collected data.
Training Schedule
3-EMTTS–Electric Motor Operational Theory
Online Course—On-Demand
With theory review and motor construction now under our belts, we will explore how motors operate. Staring with a simple AC generator we will learn how a motor develops a magnetic field in the stator and how that causes the rotor to turn. We will also learn how we achieve different RPM ranges for motors. In this topic we will also explore efficiency, motor power factor, and torque. We will also learn why it is important to use a motor of proper design for correct applications.
Training Schedule
4-EMTTS–De-Energized Electric Motor Testing
Online Course—On-Demand
In this topic we will bring together all the previous topics to display and comprehend the various testing types and methods utilized by the various motor tester manufacturers. We will incorporate the collected data from the motor testing videos and explain the analysis methods and data correlation. We will also provide some actual case studies from many “in-field” finds and successes. How to develop a motor testing program, determining criticality and the various uses for motor test instruments will also be addressed.

5-EMTTS–Energized Electric Motor Testing & Power Quality Analysis
Online Course—On-Demand
Power Quality Analysis is the first part of “Energized Electric Motor Testing.” Power Quality issues first appeared with the advent of the vacuum tube. However, in the 1980’s personal computers, PLCs, VFDs, UPSs and electronic lighting, began appearing in increasing numbers. The effects of these discontinuous loads can have deleterious effects on motors and electrical / electronic equipment in general. In this topic we learn how to use your motor tester as a power quality analyzer, to identify numerous power quality anomalies that can substantially reduce your motor longevity.

6-EMTTS–Energized Electric Motor Testing & Spectral Analysis
Online Course—On-Demand
This topic is a culmination of all the previous topic in this series. Energized motor testing is an expedient method for identifying many electrical and mechanical faults that lead to motor failure. Learn how to safely collect, analyze, and correlate test data to diagnose power supply, motor circuit and motor electrical and mechanical issues, using raw data, time domains and current and voltage signal processing (FFT) data. Learn how many of the differing types of starting circuits work and how to diagnose electrical, mechanical and circuit problems by monitoring motor starting current or in-rush.
