How
to Start and How to Stop: AC/DC Motor Control
Robert
Scoff, P.E.
Overview
The intention of this course is to show how
many types of motors are turned on and off.
A number of different AC motors are looked at, and ways to start and stop
them are addressed. Reversing
techniques are also addressed. Then
various Electronic techniques for controlling motors are addressed.
Both Alternating Current motors and Direct Current motors are covered.
All in all, this is a very nice coverage of a subject that is often
overlooked in our educational systems.
This course was designed for electrical
engineers as well as engineers of other disciplines.
Electrical engineers will have a deeper understanding of how motors are
controlled. Engineers from other
disciplines will get an idea of the problems faced by the people responsible for
making their facilities and plants run properly.
This will help engineers understand each other’s special problems.
The more that we, as engineers, understand the problems faced by other
engineers, the better that we will be able to do our specific jobs.
There is very little math involved in doing
this course. It is mainly an
explanation of how various kinds of starters and speed controls work.
Many schematic drawings are included to help engineers understand how the
devices that are covered work.
It would be almost impossible to cover all of
the various motion control devices out here in the industrial world.
I have attempted to give a good overview of the most common devices that
I have been exposed to in 25 years of industrial experience.
The student must take a multiple choice quiz consisting of 20 questions at the end of the course to obtain PDH credits.
