The EEVC1 software is designed to help North America’s electric motor service centers (MotorRewind Shops) to estimate the full-load and partial-load efficiency of 3-phase/60Hz refurbishedinduction motors. The software is supported by a database of a large number of induction motorstested in Laboratoire des Technologies de l'Énergie, Institut de Recherche, Hydro-Québec,Shawinigan, Québec, CANADA. The software is designed based on the Institute of Electrical andElectronics Engineers IEEE Std 112™-2004 and the Canadian Standards Association CAN/CSAC392-11 standards

Value and benefits provided by the EEVC1 software are:

• A tool to replace the expensive conventional method (dynamometer procedure) of testinginduction motors for efficiency estimation
• Easily used in most of North America’s electric motor centers
• Does not need any of data logging equipment
• Uses only RMS values
• Compatible with most computer Windows-based operating systems
