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.

Learning 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.
