Abstract
In order to achieve high potency for magnetic circuits together with a favourable possibility of constructing them in four-phase and two-phase form using radially positioned permanent magnets in flux concentration mode, it is proposed to introduce E-shaped stator pole elements with at least one fanned-out limb each. This gives the most favourable utilisation of the permanent magnets together with high functionality with a view to the maximum obtainable rotor diameter and favourable component manufacture. Both four-phase and two-phase machines may be constructed with the same pole elements. For exclusively two-phase windings there is a possibility of shortening the distance between the part-rotors.
