Course Description:
This course is
designed to provide engineers 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.
