Abstract

See full text

A dynamo-electric machine, for example a marine propulsion unit, includes a stator and a rotor in the form of an impeller. The impeller is rim-driven and includes an annular core of ferromagnetic material, on which are provided layers in the form of an environmental enclosure and electrically conductive sleeves. Appropriate selection of the materials and thicknesses of the layers enables the starting and normal running performance of the machine to be optimized.
