May 2012 SAIMC

At the March Technology Evening, Donald Hobson of Zest Electric Motors and Drives explained how high efficiency motors offer a number of potential benefits over typical standard types. These include lower electricity bills and reduced operating expenses through lower failure rates and longer service life. Motor efficiency is the ratio of mechanical power output to the electrical power input, usually expressed as a percentage. Energy-efficient motors use less energy to perform the same amount of work with key design improvements and more accurate manufacturing tolerances largely responsible for the increase in performance.

Motor systems consume approximately half of the energy used in the commercial and industrial sectors, so improving the efficiency can save substantial amounts of energy and reduce operating costs. High efficiency motors do cost more, but many models offer a return on investment within a relative short period of time. The cost of operating a motor in the first year is often several times the purchase price. Reducing operating costs through the purchase of higher efficiency motors can offer a substantial payback. In addition to energy savings, the better design and improved construction of high efficiency motors can lead to additional benefits such as:

* Longer insulation and bearing lives.

* Lower heat output and less vibration.

* Extended winding life.

* Increased tolerance of overload conditions.

* Higher tolerance for increased voltage rates or phase imbalance.

* Lower failure rates and extended manufacturer warranties.

Donald’s presentation was well received.
