► New Energy Efficiency Standards for electric motors

May 19th, 2014

New Energy Efficiency Standards for electric motors to save energy and reduce carbon pollution.

The Department of Energy recently released new efficiency standards for walk in coolers, freezers and electric motors. Find out how REOUnity can help you comply with these new requirements below.

► The best of both worlds

Increasing motor life and reducing EMI while increasing ROI

Business purchasing decisions are increasingly being made in a vicious cycle of short-termism, even under circumstances where a long term strategy may yield higher return on investment (ROI). At a time when austerity measures are leading businesses to cut costs, manufacturers can use high current line reactors to make considerable energy savings, increase motor life and reduce electromagnetic interference (EMI) issues.

There is no doubt that we are living in an era of unprecedented change and a world where competitiveness has captured the hearts and minds of decision makers. From lean and kaizen in manufacturing to third tier auditing in supply chains, the push towards reducing carbon emissions using green technology saving money is high on the agenda. The way has been paved rapid business growth and the rise of empires in the space of a few decades.

However, in some cases this change has come at the cost of a long term perspective. Traditionally the most successful businesses have been those whose strategy has struck a good balance between short term efficiency and long term return on investment.

Short term parochialism has often led companies into a vicious downward spiral. Many reputations have been left in tatters in the pursuit of price and chasing cheap, almost always by sacrificing long term quality and service.

Increased pressure to conform to legislative and corporate social responsibilities has further intensified the burden on companies to deliver high quality, on time and under budget. For instance, the eco design directive covering electric motors - EC 640/2009 - mandates that from January 1, 2015, all new motors must be equipped with a variable speed drive (VSD) by default.

In industrial applications a VSD is often used to control the speed of a motor. This increases efficiency and provides cost savings. However, the process is not completely without drawbacks. In order to control the motor speed, the supply current is manipulated using pulse width modulation (PWM) for high frequency switching.

The resultant fixed voltage, variable frequency supply outlet, while able to control motor speed, creates unwanted EMI and harmonic currents, whose high frequencies can damage equipment. Overheating of transformers, windings and capacitors as well as interference on telecommunications equipment and metering apparatus can render equipment unusable.
