The cost and mass of an offshore wind turbine power-train can be reduced by using high-temperature superconducting generators, but for a successful commercial design the superconducting generator should be as reliable as its alternatives. In this paper, we present a novel transverse flux superconducting generator topology which is suitable for low-speed, high-torque applications. The generator is designed with a stationary superconducting field winding and a variable reluctance claw pole motor for simplified mechanical structure and maximum reliability. 3D FEA simulation results of a 70 kW prototype is presented.

Towards more reliable and cost effective superconducting generators for wind turbines Keysan, Ozan; Burchell, J.; Mueller, M.A. (2014-01-01) For large(~10 MW) wind turbines, direct-drive superconducting generators are proposed to reduce the tower head mass, which help to reduce the installation costs. Most of the existing designs has a very similar topology: a synchronous machine with a rotating superconducting field winding. However, this topology may not be the most suitable design for harsh offshore conditions. A novel transverse flux design is presented in this paper. The design has stationary and modular superconducting field windings combi...
A direct drive permanent magnet generator design for a tidal current turbine SeaGen Keysan, Ozan; Markus, Mueller (2011-05-15) In this study, the feasibility of a direct-drive permanent magnet generator for a tidal turbine power take-off system, namely MCT's SeaGen - the world's first full scale commercial tidal turbine- has been investigated. The investigated PM generator topology is called C-GEN which is an air-cored axial-flux generator developed in the University of Edinburgh. The C-GEN is prior to conventional PM generators by absence of magnetic attraction forces between rotor and stator, absence of cogging torque, ease of ma...
A modular and cost-effective superconducting generator design for offshore wind turbines Keysan, Ozan (IOP Publishing, 2015-03-01) Superconducting generators have the potential to reduce the tower head mass for large (similar to 10 MW) offshore wind turbines. However, a high temperature superconductor generator should be as reliable as conventional generators for successful entry into the market. Most of the proposed designs use the superconducting synchronous generator concept, which has a higher cost than conventional generators and suffers from reliability issues. In this paper, a novel claw pole type of superconducting machine is p...
A Rare-Earth Free Magnetically Geared Generator for Direct-Drive Wind Turbines Zeinali, Reza; Keysan, Ozan (MDPI AG, 2019-02-01) A novel Vernier type magnetically geared direct-drive generator for large wind turbines is introduced in this paper. Conventional Vernier-type machines and most of the direct-drive wind turbine generators use excessive amount of permanent magnet, which increases the overall cost and makes the manufacturing process challenging. In this paper, an electrically excited (PM_less) claw-pole type Vernier machine is presented. This new topology has the potential of reducing mass and cost of the generator, and can m...
An open source tool to estimate mass and efficiency of wind turbine power take-off systems Keysan, Ozan (2013-12-01) This paper presents mass and efficiency estimations for wind turbine drive-train components. Data from literature and commercial catalogues are collected to obtain trend lines for each component. Different gearbox and generator types are investigated as well as the bearing and the low-speed shaft. An open-source tool is presented to compare different power take-off options in terms of weight and efficiency. The datasets and the user interface made available as an open source tool and can be accessed at GitHub.
