Abstract
This paper discusses the modelling of magnetic field distributions in disk drive spindle motors using a combined finite element and analytic al approach. The torque analysis of a spindle motor having NdFeB magne t poles is also presented. It is shown that the proposed method pro,id es an effective tool for reliable torque computation in contrast to co nventional finite element schemes,
