Summary on Grant Application Form |
|
It has been estimated that in Europe, induction machines consume around 50% of all electricity generated. In an effort to reduce 'greenhouse gases', the EU is taking steps to encourage the use of higher efficiency motors, including a voluntary labelling scheme for efficiency bands and a motor database (EURODEEM) which will store details of motors from all major manufacturers. One of the few avenues open to a manufacturer seeking a large improvement in efficiency involves using hybrid permanent magnet-induction machines, often known as line start permanent magnet (LSPM) motors. These machines generally comprise a conventional n-pole induction machine stator and a special rotor. The rotor is fitted with a conventional rotor cage and also permanent magnets, the latter so as to provide n rotor poles. The conductors on the rotor provide asynchronous torque to accelerate the rotor from rest and the permanet magnets provide synchronising torque to lock the rotor in at synchronous speed.The proposed work is aimed at developing greater understanding of the action of these machines and also good methodology for their optimised design. Several prototype LSPMs, including conventional radial flux cylindrical and axial flux 'pancake' machines will be built and tested.
