Abstract of the Disclosure An adjustable speed inductor type rotating dynamoelectric machine, capable of high speed operation, employs a stator assembly incorporating a spool-like support structure. A central, generally cylindrical portion of the support structure supports field windings while radially oriented end portions of the spool-like structure mount and accurately position a circumferentially distributed plurality of C-shaped armature core elements. Radially directed, angularly spaced grooves in the outer surfaces of the end portions receive legs of the C-shaped armature elements and serve to precisely position these elements in three orthogonal directions. The central portion of the armature-field winding support structure may be made of electrically conductive material to provide a flux shield and dissipate heat. For additional ventilation, cooling ports may be provided in the central portion of the spool-like support which cooperate with extended recesses in a coaxial rotor. The rotating rotor centrifugally propels cooling fluid through said ports into the spaces occupied by the field windings and armature windings.
