ABB motor reaches almost 100% energy efficiency – saves half a million dollars

Tests carried out on a 44 megawatt 6-pole synchronous ABB motor shortly before delivery showed an efficiency 0.25 percent greater than the 98.8 percent stipulated in the contract, resulting in the world record for electric motor efficiency. This efficiency improvement could save approximately $500,000 in electrical energy costs over the course of a 20-year lifetime for each motor.

“With electricity costs being, by far, the largest component in the total cost of ownership of such a motor, savings like these have a significant impact on profits,” said Sami Atiya, president of ABB’s Robotic and Motion division. “In addition to extremely high efficiency, synchronous motors are renowned for their proven quality and reliability. Their robust design ensures reliability through cool operation temperatures and low vibration.
