ABSTRACT:
A dynamoelectric machine includes a frame, a shaft rotatably mounted on the frame and a cylindrical rotor mounted on the shaft. The rotor is provided with rotor coil winding grooves parallel to the shaft. A distributed armature winding is received within the grooves and create a build-up of windings which gradually increased dimensions in the region of the shaft, the build-up defining a conical convex surface. Permanent magnets are arranged proximate to the overlapping windings at the axial ends to produce a closed cylindrically shaped magnet to maximize the interaction between the magnets and the rotor.
