    Abstract: This invention relates to a rotor assembly for use in a dynamo electric machine, the rotor assembly having two parts which are mounted on a rotor shaft, each of the paths having a periphery a plurality of pole pieces of generally trapezoidal shape which extend in a direction substantially parallel to the axis of the rotor shaft. The pole pieces of the two paths are interdigitated and arranged such that in use the pole pieces associated with the two parts have opposite polarities, the non parallel sides of each pole piece being spaced from the adjacent sides of adjacent pole pieces and a portion of the outer face of each pole piece being of part cylindrical configuration. The outer edges of the sides of each pole piece when seen in developed plan view are inclined relative to the rotor axis by different amounts and a relieved portion is provided in the outer face adjacent to one of these edges so that the part cylindrical portion of the outer face has substantially the shape of an isoscelese trapezium.

    Abstract: In a rotating electrical machine having a pole ring having poles which extend towards the airgap between the stator and the rotor and which are formed with winding slots extending parallel to the rotor axis, the winding extending radially through the winding slots, the pole surfaces near the airgap are larger than the smallest cross sections of the poles. The armatures of such rotating machines can in known manner be formed by spirally coiled strip. A rotating electrical machine of this kind makes a very good pump motor of the kind wherein a partition provides a sealingtight separation between the driven element and the driving element.
