Course Description:
This course is
designed to provide construction professionals with a thorough understanding of
motor and drive system components and methods to increase performance using a
systems approach. The course details the
content of the sourcebook for Improving
Motor & Drive Systems, authored and developed by the United States
Department of Energy. Part 1 of the
course highlights the advantages of a “system approach”; compares and contrasts
the application of AC and DC motors; discusses the drawbacks of both oversized
and undersized motors; and outlines different types of motors and their
advantages and disadvantages as well as the characteristics of motors.
Course Learning Objectives:
·
To emphasize the
advantages of utilizing a “systems approach” in designing, improving and
maintaining motor and drive systems,
·
To identify and
discuss the proper applications and classes of Direct and Alternating current
motors within pertinent industrial applications, and
·
To illustrate the
relationship between power consumption and operating speed, including the
implications of both under- and over-sized motors.
Course Outline:
Section 1- Motor and Drive System Basics – Pinpoints the amount of energy
used by motor and drive systems in each major industrial group; Emphasizes the
importance of proper motor selection and maintenance; Details the advantages of
a systems approach in achieving cost effective operation and maintenance;
Discusses system optimization in terms of varying environmental conditions and
production demands; Relays the various negative impacts of having an
inefficient motor and drive system, (including poor working conditions); and
Pinpoints the indications of a poorly designed system.
Learning Exercise 1
Section 2- Motor Types - Outlines the differences between the two types of electric
motors (based on how electricity is supplied), Alternating Current and Direct
Current, and the advantages of each; Identifies the principal classes of motors
within those two primary categories, there are 4 principal classes of dc motors
and 2 principal classes of ac motors; Pinpoints the pros and cons of each type
of motor and their applications; Provides the equation for determining
synchronous speed in an ac motor; Discusses “slip”, the difference between
actual speed and synchronous speed in ac induction motors; and Highlights some
exciting power electronics improvements that may be suitable for particular
applications.
Learning Exercise 2
Section 3- Motor Characteristics - Reviews the operating
characteristics of motors such as horsepower, operating speed and torque and
provides the equation for understanding the relationship between them;
Discusses the severe effects of mismatched voltages; Outlines the factors that
affect operating speed in both ac and dc motors and various types of speed
adjustment devices; Discusses the important consideration of constant versus
variable speed, which is application dependent; Highlights the advantages of
using VFDs and multiple-speed motors to control speed
in induction motors; and Discusses torque (which changes with 4 basic types of
loads) as a fundamental factor in motor performance.
Section 4- Motor & Drive Application – Outlines the basic
requirements of service that should be considered in the selection of a motor
for a particular application; Pinpoints the suitability of various motor types
to specific industrial applications (mainly to drive pumps, fans, and
compressors); Discusses the advantages and efficient incorporation of
Adjustable Speed Drives; Examines a couple of useful assessment tools such as
the Fan System Assessment Tool (FSAT) and Pumping System Assessment Tool
(PSAT); and Identifies frequent motor problems such as, part-load operations, oversized motors,
undersized motors and reactive power.

Exercise 3
Method of
Presentation:
This
is an online course that consists of collegiate-style lectures that have been
professionally narrated by subject matter experts, animated with relevant
graphics and media, and converted to Flash for web
delivery to provide licensees with a first-rate learning experience.
Evaluation Method:
Licensees will be
evaluated on their comprehension of the material covered by administering Three
(3) brief learning exercises, interspersed throughout the course, upon which
successful completion of each is
required before advancement to the next section is allowed or course credit is
earned. If the licensing board requires
the licensee to pass a final examination, course credit will not be earned
until the final exam has been completed to the required proficiency level.
