A new concept for weight reduction of large direct drive machines

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 machine. The weight of the rotor using the new concept is compared to a rotor designed with conventional methods. The comparison of a 5 MW generator rotor structural material shows about 45% reduction of weight of the rotor.
