Three-Phase Induction Motors Energy Efficiency Standards-- A Case Study –

The efforts to reduce the energy consumption begin with its main load, the induction motor. There is a world agreement that this objective can be achieved by motors efficiency regulation. The Brazilian Government has already approved regulations establishing mandatory limits for Standards and High Efficiency Motors. This paper analyzes the results achieved so far through tests realized at LAMOTRIZ/DEE-UFC with both types of motors and points to the challenges that the domestic industry will have to overcome to improve even more these machines efficiency
