The aim of this paper is to design a lightweight transverse flux permanent magnet (TFPM) machine for large scale direct-drive wind turbines. The requirements for suitable
generator systems for wind turbines are discussed. Analytical modeling of TFPM machines is discussed by consi

A direct drive generator used in wind turbine has high energy yield compared to other drivetrain topologies and low maintenance is expected as the technology matures. On the other hand direct drive generator weight and size increases rapidly when scaled up to larger units. This p

Abstract
Upscaling of wind turbines affects the individual components in the wind turbine. In order to assess the effects of upscaling on the direct drive generator used in wind turbines, the weight and size of the generator sub-components should be estimated. A method to estimat

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 t

This paper looks into a new concept for reducing the structural weight of large direct-drive generators used in wind turbines. The concept uses magnetic bearings to position the rotor of the generator. The use of magnetic bearings allows structural flexibility in the generator. T
