A lightweight low speed permanent magnet electrical generator for direct-drive wind turbines
نویسندگان
چکیده
The evolution, design and test results of a novel permanent magnet generator for use in direct-drive wind turbines are presented. The novelty in the concept lies in the arrangement of electromagnetically active components – magnets, steel and copper – such that the structural mass can be reduced. It has also been designed such that during the assembly of large diameter permanent magnet machines there are no magnetic forces to worry about.

متن کاملReview in Transverse Flux Permanent Magnet Generator Design
Recently, Transverse Flux Permanent Magnet Generators (TFPMGs) have been proposed as a possible generator in direct drive variable speed wind turbines due to their unique merits. Generally, the quality of output power in these systems is lower than multi stage fixed speed systems, because of removing the gears, so it’s important to design these kinds of generators with low ripple and lowe...
