Abstract
A formulation for the airgap field distribution due to a single slot current has been found, allowing the construction of arbitrary windings by the superposition of these solutions. A novel technique has been devised for simulating the finite length of the stator iron by reactive sheets lining the iron beyond the stator ends such that the currents induced in these sheets shield the excess iron. This model reveals the presence of synchronous (i.e. reluctance) forces in linear machines which have not been previously discussed. The results are compared with published experimental data.Keywords
