Interest in permanent magnet machines has gained momentum with the introduction of NdFeB alloys. However magnet cost is still relatively high and therefore design parameters have to be chosen carefully so as to minimize the volume of the magnet used for any particular application. This paper concerns the derivation of a mathematical expression that determines the optimum rotor/stator diameter ratio, known as the split ratio, in relation to other machine parameters. The analysis takes into account the demagnetizing effect of the load current on the magnet material and consequently the feasibility of the optimized design is examined. This analysis is then applied to several existing designs and the results indicate that the appropriate choice of the split ratio would lead to a significant reduction in the magnet volume and hence in the machine cost. |
