Spherical Generator
Staff at the Robert Gordon University, motivated by the idea of a lightweight superconducting generator providing large amounts of power for airborne applications, developed the design of a spherical turbine in 2004. The first prototype, built around a ‘dog ball’, made the concept a reality.
The area of turbine/pump and generator/motors is receiving a lot of attention due to the focus on clean and renewable sources of energy. It is recognised that the success of technologies in this area is largely dependent on the creation of efficiencies that maximise the cost/benefit ratio.
Robert Gordon University has two low speed, wind powered working prototypes and requires partners to assist with the development of application specific prototypes. Beyond initial investment Robert Gordon University would be interested in a joint venture to take to market or would consider licensing on an application basis.Key Benefits
- smaller volume than cylindrical designs with the same surface area
- increased stability as rotating components on the same neutral axis
- uniform spherical magnetic field stabilising the rotor
- uniform spherical magnetic flux increasing efficiency
- flywheel providing stability and compensation for load fluctuations
- geared without a gearbox or drive train reducing moving parts and wear
- direct transfer of energy from the load source increasing efficiency
- globally modularity reducing maintenance costs and increase availability in an array
- internal modularity for easy application to a range of conditions or change in conditions
Applications
- Wind Turbine (including Micro turbines)
- Gas/Steam Turbines
- Automotive micro turbines/flywheel
- Electro-mechanical battery (flywheel energy storage)
- Fluid pump or flow regulator
- Vacuum and High Pressure Cleaners
