چکیده

The objective of this paper is to identify suitable generator concepts for direct-drive wind turbines by reviewing directdrive and geared generator systems. Usually, in literature, comparison of different generator systems is discussed with the criteria based on the energy yield, cost, and weight. Because direct-drive permanent-magnet machines are more superior in terms of the energy yield, reliability and maintenance problem, different promising permanent-magnet machines proposed in literature are also discussed to find suitable generator type. Finally, suitable concepts to overcome the disadvantages of direct-drive are suggested considering both electromagnetic and mechanical structure.

Cogging Torque Reduction in a Permanent Magnet Wind Turbine Generator: Preprint

Most small wind turbines use permanent magnet (PM) generators. The generators are usually direct-drive (i.e., no gearbox is required). Direct-drive PM generators are characterized by low maintenance and high efficiency. Small wind turbines are usually self-starting and require very simple controls. Cogging torque is an inherent characteristic of PM generators and is caused by the geometry of th...
