Hotel ECM motor retrofit saves 400,000kW per annum 27 May 2014

One of Boston's (North America) most famous hotels is reaping the benefits of massive energy savings, as well as delivering on its commitment to protect the environment, thanks to a retrofit of energy-efficient motors.

Electronically-commutated motors (ECM) from Regal Beloit have been installed in more than 800 rooms at the Westin Copley Place Hotel, providing motive drive right down to air conditioning systems.

The hotel's engineering department selected the ECM motor technology because it is based on a brushless dc permanent magnet design that is more efficient than standard induction motors commonly found in air handlers, air conditioners and refrigeration applications.

By combining electronic controls with brushless dc motors, the latest generation ECMs can maintain efficiency across a wide range of operating speeds.

When the Westin engineering team investigated these motors, they found they were up to 80% more efficient than the existing motors used throughout the hotel.

Not only did this offer significant ongoing savings in running costs, it also meant saving the equivalent of 282 tonnes of CO2.
