Purpose of Seminar:
A one-day hands-on seminar originally designed for non-electricians, this seminar is
designed to teach non-electricians, such as maintenance technicians, instrumentation
technicians, HVAC technicians and others who occasionally must troubleshoot, test and
replace electric motors how to safely and correctly do the job. If you want to use this
course for experienced electricians, let us know, and we will take it up a notch or two
when we cover motor types, troubleshooting and testing of rotating electrical equipment.
The hands-on portion will become an excellent opportunity for the experienced electrician
to review the latest in motor troubleshooting and testing technology.
This is an excellent opportunity to save money on training while your plant personnel learn
on the very same equipment they use in the field. American Trainco supplies the books,
training materials and an experienced electrical instructor equipped with hardhat, safety
shoes, eye and hearing protection, ready to teach in your facility. You supply what you
already have – the tools and test equipment your technicians use every day. Additionally,
spare motors in the shop, failed motors or motors not being used in the field are all used
for hands-on exercises. Quite often, if you desire, your local motor distributor may be
willing to supply additional motors for training. Let us know what you have or what you
need and we’ll coordinate with you to make your hands-on training a success.
Who should take this course?
Maintenance technicians, instrumentation technicians, HVAC technicians and other
non-electricians who occasionally must troubleshoot, test and replace electric motors.
