Summary on Grant Application Form |

Mechanical gearboxes are used extensively to match the operating speed of prime-movers to the requirements of their loads, both for increasing the rotational speed (e.g. wind-powered generators) and decreasing the speed (e.g. electric-ship propulsion), since it is usually more cost and weight effective to employ a high-speed electrical machine together with a gearbox to transform speed and torque. However, although high system torque densities can then be achieved, gearboxes usually require lubrication and cooling, whilst noise, vibration and reliability can be significant issues. Magnetic gears can offer several advantages, such as reduced acoustic noise and vibration, lower maintenance and improved reliability, precise peak torque transmission capability, inherent overload protection and physical isolation between input and output shafts.It proposed to research the performance of radial-field and axial-field magnetic gears, by developing analytical models relating key design parameters to the transmitted torque capability and investigating their influence on the torque density and the operational efficiency. Design guidelines will be generated, and alternative methods of construction will be considered. The findings will be validated on technology demonstrators. It is also proposed to research the relative merits of different ways of integrating a magnetic gear with an electircal machine, in order to realise a high torque density'pseudo' direct-drive.
