Abstract
The theory of a permanent-magnet d.c. machine that has an axial field and a disc-shaped armature is discussed. Consideration is given to the effect that the distribution of magnetic field inthe airgap will have on the generation of e.m.f. The machine parameters in the angular and radialdirections are related to this distribution, so that a pole shape may be chosen that maximises the output power.Keywords
