Even a one percentage point gain in efficiency results in big energy savings. When you consider that motor-driven equipment accounts for some 70 percent of our country's industrial electricity consumption, these motors (copper rotors) are good for the environment as well as the bottom line." Dr. John Cowie, CDA project manager
Agenda
Energy Efficient Motors and the Role of the Copper Rotor Motor
Richard E. deFay,
Copper Development Association, Inc.
New copper technologies show a bright future in motor energy efficiency. The role of motors and motor efficiency play a large factor in reducing electric consumption. This presentation will cover:
- How copper rotors are revolutionizing the motor market
- The cutting edge in motor efficiency and what is on the horizon
The experience of the presenter in conducting more than 60 on-site motor audits in New York State will be discussed along with the implications of corrective action and the commensurate cost savings available. Case studies will be presented that demonstrate the significant savings available.
The presentation will also include the implications of the new copper rotor motor, pending world trends to improve motor efficiency and what is on the horizon.
Beyond ASHRAE 90.1-2004 Strategies/Systems for Using 30% Less
Susanna Hanson,
Senior Applications Engineer for Trane
Dissatisfied with just doing the bare minimum, a growing number of building owners and jurisdictions (states, cities, organizations) are looking for ways to make buildings use less energy. While the recent explosive buzz from new "green" guidelines and rating programs has elevated the level of conscious effort, it has also created a lot of confusion. What have we learned from all this renewed focus on environmental stewardship? Has the process of seeking "green" recognition gotten in the way of the very real economic payoff? Distill some of the good ideas from these "above-code" programs that have a tendency to get buried in the scorecards, with specific focus on the mechanical systems.

The Expanding Role of Permanent Magnet Machines in the Global Marketplace
Thomas M. Jahns, Professor,
University of Wisconsin - Madison
Permanent magnet synchronous machines and their associated drives have experienced rapid increases in both their technological state-of-the-art and market penetration during recent years. This presentation will review several of the major factors that have contributed to this progress, including key advances in the development of permanent magnet (PM) materials, PM synchronous machine (PMSM) configurations, and their associated adjustable-speed drives. Special attention will be devoted to reviewing the significant progress that has been achieved in developing PM machines and drives for electric traction applications. The presentation will conclude with a discussion of the key challenges and trends that are likely to significantly influence the future development and market success of new generations of PM synchronous machines and drives.
Integrating Adjustable-Speed Drive Capabilities into
Tomorrow's Electric Motors
Ben Sykora, Graduate Student, ECE Department, UW-Madison
The Integrated Modular Motor Drive (IMMD) concept provides a promising approach to the integration of motor drive electronics into a motor housing by modularizing both the machine stator and the power converter. The basic module of the IMMD consists of a stator pole-piece wound with a concentrated coil and fitted with a dedicated power converter unit. This presentation introduces the IMMD concept and reviews several of the technical challenges associated with its development. The current state of prototype IMMD development will be described including a summary of future concept demonstration plans and application opportunities.
The Hybrid AC System
Day Gas/Night Electric
Megan Sharrow,
UW Madison Engineering Graduate Student
Megan Sharrow, WPUI's research assistant will report on a project she is working on with Lamonte Wilder of the Masters Academy to evaluate the net energy impact of using a day-time gas, night-time electric air conditioning system.
