DYNAMO ELECTRIC MACHINE WITH STATOR WINDINGS DISPOSED IN THE ROTOR-STATOR AIR GAP

摘要

A dynamo electric machine which has a stator winding disposed in the rotor-stator air gap. The rotor winding comprises coils having straight axially extending side portions which are supported in trough members which have radially extending side walls the outer ends of which fit into slots in the stator core. The troughs may have cover plates also having side walls extending into the stator slots, and the troughs with the windings therein form a cylindrical structure in the air gap. This structure can be held in position closely adjacent the stator core by conformable packing or wedges associated with the side walls of the troughs and the stator slots.
