Power generators with high efficiency for marine applications, such as ships and military applications are planned.
Recently, wind turbine design optimization philosophy has been shifting from a predominant reliance on gearboxes towards an increased use of direct-drive technology with permanent magnet generators (PMGs). This trend has been motivated by customer demand for increased reliability (following experiences with bearing-related gearbox failures) and the higher power-to-weight ratios attainable in turbines with direct drives. Across the entire wind power market, direct drives will take 25% market share by 2015 (Navigant).
EVR Motors developed & tested a patent-pending novel, direct drive generator for variable RPM (Revolutions Per Minute) input sources. The technology is based on a unique design of the generator magnetic system and topology.
Our novel design enables the use of magnets in the generator from both sides, removes entirely the iron from the rotor, and less electrical steel is being used.
As such our generator uses significantly less iron, magnets and copper.
• Lightweight – at least 50% lighter than others (~10kg/kW), leading to a cost reduction of the turbine & its installation.
• High efficiency – above 94%, leading to significant increase in the capacity factor of the turbine.
• No need for expensive transformer in off-grid systems – the generator can directly produce low voltage & high current.
• Attractive prices.
