Time For A Transplant? The purchase price of a motor represents just 2% to 5% of the cost of ownership of a eh f motor. The balance of the cost is the energy to s operate the motor. NYSERDA has program representatives that work with endusers and a their vendors in the New York Energy $mart Program area, g t to help make the enduser’s facility as energy efficient as c possible. Every energy y g dollar saved goes directly to the enduser’s bottom line, improving the company’s financial health. installed. This software enables the enduser to continue to update his inventory as maintenance and/or motor replacement occurs. What kind of results can you expect? If your motors are 10 or more years old, number at least 20 motors of 5 hp and above, and operate from 10 to 12 hrs a day, you could save several thousand dollars a year. Typically, in the average motor audit, approximately 10% of the motors are candidates for immediate replacement and 50% are candidates for replacement at failure. These numbers vary, but over the 90 inventories conducted, the averages have held. A typical motor audit involves 25 to 50 motors and, depending on access, can be completed in one to two days. It may take approximately a week or more to enter all the data into a database and perform the analysis. Upon completion of the analysis, program reps meet with the enduser and motor vendor to discuss the results, deliver and install the MotorMaster+ software, and the database, and are always available to answer questions, provide training, and offer help where needed. PROGRAM RESULTS The motor management phase of the program began in 2005, and the program has since completed 90 inventories of over 8,300 motors. The program has identified more than 7.7 million kWh and more than 1,070 kW in potential energy savings if all the candidate motors were replaced when suggested by the program’s analysis. Overall, 52% of the motors inventoried were candidates to be replaced at failure with a NEMA Premium motor and almost 12% of the motors inventoried were candidates to be replaced immediately with a NEMA Premium motor. Additionally, approximately 85% of the motors inventoried were not NEMA Premium motors. Ultimately, NYSERDA would like every enduser in New York to have a motor management plan in place. Whether they have a handful of motors or several thousand in operation, there should be a docu66 En gi neer ed S y stem s June 2008 ment that details what will happen when each motor fails. In some cases, because of its application, a motor must be repaired at failure. Motors that fit into that category should be identified and the repair process should be clearly known by all parties in advance of failure. The vendor selected to repair the motor should also be identified in advance and have a known reputation to follow the most advanced repair techniques available. Losing efficiency in a repair is unacceptable and can be costly over the life of the motor. It is essential to understand that the purchase price of a motor represents just 2% to 5% of the cost of ownership of a motor. The balance of the cost is the energy to operate the motor. NYSERDA has program representatives that work with endusers and their vendors in the New York Energy $mart Program area, to help make the endusers’ facility as energy efficient as possible.

To find out if your facility is eligible for an audit through the New York Energy $mart Program, or for more information, contact Ed Evans at 800-388-9294 or by e-mail at ed@appliedproactive.com. If you are located outside of New York, there may be resources for motor management activities in your area. Motor Decisions Matter (MDM) is a national campaign for raising awareness on motor management and providing support for companies interested in it. A consortium of motor manufacturers, motor service centers, trade associations, electric utilities, and government agencies, including NYSERDA, sponsors the MDM campaign. The MDM website at www.motorsmatter.org contains information, such as a summary of energy efficiency programs throughout the U.S. and Canada, and tools, such as the Motor Planning Kit and the 1·2·3 Approach to Motor Management, you can use to develop a motor management plan that meets your company’s needs. The information can also lead to partnerships with your local sales and service center, vendor, utility, or other energy-efficiency representatives who may offer added support. For more information, contact MDMinfo@cee1.org.
