The aim of this paper is to review direct-drive generators and to propose promising direct-drive generator concepts for large wind turbines. Different large direct-drive generators are compared based on the mass and the torque rating. Features of different PM machines are investigated to find a suitable machine type for direct-drive. Some promising solutions are proposed for both electromagnetic and mechanical design.
