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. windmill-powered generators) and decreasing the speed (e.g. electric-ship propulsion). 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 gearing offers several advantages, such as, reduced acoustic noise and vibration, reduced maintenance and improved reliability, precise peak torque transmission capability and physical isolation between input and output shafts. However, to date, magnetic gears have received relatively little attention.It is proposed to research the design and performance of high-performance magnetic gears, by developing an analytical model 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 a technology demonstrator. Finally, issues related to the subsequent integration of a magnetic gear with an elctrical machine will be addressed.
