Summary on Grant Application Form |
|
Central to the project is an experimental programme to measure stator and rotor electromagnetic losses in very high-speed (up to 100,000 r/min) permanent-magnetic machines. Rotor losses in the conducting magnets, and possibly also the retaining sleeve, due to eddy currents induced by harmonic fields, are a major concern. So also is the identification of operating conditions and constructional methods that may lead to excessive loss in the stator laminated core. Losses in generators feeding rectifier loads and inverter-fed motors are of special interest. There are potentially large international growth markets for both high-speed generators and motors. Test results will be compared with analytical and computational predictions, using methods recently developed by the Investigators, and the aim is to gain a full understanding of the parameters influencing all the components of loss. A precision test rig will be developed, in which a full variety of stator/rotor assemblies can be rapidly investigated. The studies of rotor loss mechanisms are readily applicable to conventional synchronous machines, and the fully developed and validated computational methods will also be applied to large salient-pole generators and inverter-fed motors. A PhD student will further extend this work, to more detailed loss estimates and possibly asynchronous torque prediction.
