The stator mmf over a segment of the segmental rotor reluctance machine is treated as an infinite array of generators feeding a common busbar, and the magnetic potential of the rotor segment is obtained as the potential of the equivalent busbar. The rotor potential for any airgap profile is readily obtained and it is shown how the method may be extended to axially laminated machines and those of the flux barrier type. This approach is derived from considering the flux due to a single stator conductor carrying current.
