Abstract

We have investigated the properties of a superconducting direct drive generator suitable for demonstration in a small scale 11 kW wind turbine. The engineering current density of the superconducting field windings is based on properties of coated conductors wound into coils holding of the order 68 meters of tape. The active mass of the generators has been investigated as function of the number of poles and a 4 pole generator is suggested as a feasible starting point of an in-field demonstration of the system reliability. An active mass of m = 421 kg and a usage of 3.45 km of tape will be needed to realize such a generator with a peak flux density in the airgap of B0 = 1.5 T.
