To use this tool, first ensure that

To use this tool, first ensure that each motor is assigned a permanent identification number. Then gather motor nameplate information. It is easiest to use a cell phone to take a picture of a motor’s nameplate, then enter the available information into the spreadsheet tool. (when collecting nameplate information, be sure to bring steel wool, a wire brush, flashlight, spray bottle of cleaning solution, and a mirror). Make sure that the motor inventory contains both in-service and spare motors. The tool uses this nameplate data to determine the efficiency class of each motor, and then uses field measurements or power survey results to estimate the load imposed upon the motor by the driven equipment. The tool allows the user to customize their version of the tool through entering local electrical utility rates, IE3 or Premium Efficiency replacement motor costs, and in-plant motor installation costs. These costs are then used to determine whether it is cost-effective for each operating motor to be replaced immediately with an IE3 model; replaced at the motor’s time of failure; or repaired and returned to service.
