Abstract

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