Public Course
This EMT course is designed to support offline motor testing. It includes electrical theory, motor construction and the detection of failure modes.
Public Course
The intent of The Snell Group's training is to provide trainees with the theoretical knowledge and procedural awareness to utilize current time domains, and spectral data to localize electrical and mechanical anomalies that affect motor performance and reliability.
Public Course
Manufacturers of motor testing equipment all use similar methods of data collection for the analysis of motors and motor circuit faults online. Their respective training courses are geared toward the operation of their particular equipment, with a great deal of time spent on software.
Public Course
This course focuses on the application of infrared thermography for advanced building diagnostics. Participants will learn how infrared is used to analyze energy, moisture, and mechanical related problems in all types of structures, residential and commercial.

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.

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.

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.

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.

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.

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.
