Sample text

Alternatively, the performance of a surface mounted PMG is improved by the addition of saliency. This paper focuses on the modelling of the DSPMG, without comparing its performance with other types of generator. Figure 15. Cross-section of the Doubly Salient Permanent Magnet Generator (Sarlioglu & Lipo, 1998). , 1998). This is a modular construction, which should make it easy to maintain. Like the transverse flux machines, for this design a complete rotor/stator unit is required for each phase.

The static magnetic field energy and co-energy must be obtained from the FEM solution - like the force performance. The static flux linkages may be calculated by summing their energies and dividing by the current flowing in each calculation when the rotor position is kept constant. λ (i , x ) = W f (i , x ) + W C O (i , x ) i where i is the armature current and x is the rotor position. A magnetisation curve is plotted for each rotor position, which is changed by altering the size of the air gap in the model.

Flat magnets are surface mounted magnets and embedded magnets are internal in the rotor structure. Finally, flux concentration means that soft iron pole pieces are fitted to the permanent magnets. , 1997). The various topologies are referred to by the city/university where they were developed; • • • Southampton: Single-Sided with Surface Magnets (SSSM) Aachen: SSSM with non-conducting stator bridges Braunschweig/Newcastle: Double-Sided with Flux Concentration (DSFC) The findings of this study are that the SSSM machines from Southampton and Aachen can deliver approximately the same torque: circa Tspec = 30 kNm/m3.
