AEG Electric Motors is extending its field of expertise to include generators for the renewable energy industry.

AEG Electric Motors is extending its field of expertise to include generators for the renewable energy industry.

AEG's latest success in the renewable energy field is its partnership with Windsave, a manufacturer of a wind turbines for the UK market.

The turbine, called the Windsave WS1000, will generate up to 1kW (12m/s wind speed) and can operate in winds speeds as low as 3m/s.

The electricity generated is supplementary and synchronised to match the exact voltage of that supplied by the National Grid, and is sufficient to contribute towards providing power to operate a TV, DVD player, fridge freezer and several lights.

Initial field trials of the Windsave wind turbine have proved so successful that British Gas has signed an agreement to undertake further trials with the view to market, install and maintain the product.

The Windsave turbine, being considerably less expensive than anything else on the market, together with its unique ability to connect and feed into the consumers' household supply, will be eligible for Government green energy grants and ongoing rebates.

With such grants, the turbine is said to be able to pay for itself in less than five years at today's electricity prices.

The generator, developed by AEG to meet Windsave's design performance and sise requirements, is the product of combined input from the company's squirrel cage induction motor technology centre at San Dona di Piave and its permanent magnet motor expertise from Noventa di Piave, both located in Italy.

From first contact by Windsave in July 2004, AEG was able to supply a prototype for initial trials in under four weeks.

Following detail refinements, the first bulk order for the generators was received in October and delivered in December.

The generator is based on the company's 90mm frame motor and included in its design features is a specially developed braking system that prevents over speed in high winds.

It also has special rotor laminations and windings to maximise efficiency, along with rare earth magnets to achieve the rated power output.

"The green energy generating market is becoming increasingly important to us", says Nigel Evenett, Managing Director of AEG Electric Motors.

"And we see our involvement with Windsave, leaders in domestic wind power generation, as central to our development in this field".
