Large manufacturers wanting to rein in their electricity costs will increasingly demand evidence that repaired electric motors match the efficiency of new motors, as a national programme to promote high-quality rewinding gathers pace.

How can lighting designers use intelligent controls to improve building energy management? Philips Dynalite energy management segment manager, Brett Annesley, explains how an environmentally sustainable development (ESD) strategy can deliver energy efficiency outcomes, while addressing indoor environmental quality (IEQ) and changing occupancy requirements.

Enclosures have to be amongst the most under-rated part of the electrical technology business. Yet they remain one of the most critical factors in ongoing performance. So you’d imagine that our local enclosure retailers would be champing at the bit to tell us about their latest products, new systems or how they see 2010 panning out, wouldn’t you? Er, no!

Power factor and harmonics are the two most common power quality issues affecting large energy users.

If 2009 went down as the year LEDs arrived, then surely 2010 will mark their acceptance as the de facto illumination choice not only based on cost and their environmental suitability, but also now it seems too – flexibility.

World-leading Auckland researchers have been eliminating the need for wires to supply power for 20 years and their technology could soon underpin a new breakthrough – charging electric vehicles.

A CAM follower, also known as a track follower or load runner, is a specialised type of roller or needle bearing roller designed to follow cams.

It goes without saying that motors and drives are critical components advancing our innovative, reliable and increasingly energy-efficient industry.
