Information : Induction Motor Performance Evaluation Tool
The Induction Motor Performance Evaluation Tool 96 (IMPET96) is a software program which computes the derived parameters of a motor such as efficiency, load, and current. IMPET96 can evaluate existing motor systems, and help determine whether adjustments or replacements are needed. The motor’s nameplate supplies the required input for operating the software. The only input which the user needs to measure is the operating speed of the motor. IMPET96's calculations are modeled after a modified version of IEEE’s Equivalent Circuit.
Voltage measurements are often difficult and quite dangerous to measure in the field. Since IMPET96 can perform an evaluation without using a motor’s voltage, the program eliminates this situation for the user. IMPET96 also provides an advanced operating mode option which allows the user to adjust for variations in nameplate data by overriding the program’s assumptions. IMPET96 can currently be licensed through the Technology Transfer Office at Oak Ridge National Laboratory (ORNL).
Currently, an advanced version called Induction Motor Performance Evaluation Tool 2000 is being developed. It will provide a more detailed performance analysis of motor systems, and be able to validate or detect any inaccuracies in nameplate data. This software program may also be able to compute nameplate efficiency by having the user take measurements at three different load levels.
