Course Summary:

This course will assist you to establish a facility energy-management program, to identify and evaluate energy conservation opportunities involving motor-driven equipment, and to design a motor improvement plan. These actions will help you:

  • Reduce energy costs,
  • Improve motor-driven system reliability and efficiency,
  • Increase productivity, and
  • Minimize unscheduled downtime.

In the course you will find:

  • How to set up a successful energy management program (Chapter 1).
  • How you can use utility bills, plant production data, and utility rate information to “target” potentially cost-effective energy conservation, demand reduction and power factor correction opportunities (Chapter 2).
  • Plant distribution system troubleshooting and “tune-up” tips (Chapter 3).
  • A description of motor testing instruments and field survey techniques (Chapter 4).
  • Methodologies for analyzing motor improvement opportunities (Chapter 5). Chapter 5 illustrates how you can use measured information to determine the load imposed on the motor by driven equipment and its efficiency at that load point.
  • How to determine the dollar benefits associated with appropriate energy conservation and demand reduction actions (Chapter 6).
  • Motor improvement planning basics (Chapter 7). This chapter provides advice regarding the assessment of new motor purchase, repair, downsizing, and replacement decisions and shows how to incorporate findings into your motor improvement plan.
  • Power factor correction assessment techniques (Chapter 8). This chapter gives examples illustrating the sensitivity of power factor correction benefits to utility rate schedules.
  • How to establish both preventative and predictive maintenance programs (Chapter 9).

Throughout this course we identify sources of additional information, such as Motor Master+. Motor Master+ is an energy-efficient motor selection and energy management software package. The capabilities of Motor Master+ include:

  • Automatic motor load and efficiency estimation based upon field data measurements.
  • Ability to select replacement motors from an internal database of over 27,000 one-to-2,000 hp NEMA Design B, C and D motors.
  • Ability to analyze conservation benefits due to purchase and use of energy efficient motors in new, rewind, or retrofit applications.
