Abstract
A dynamoelectric machine having coaxial inner and outer stators and, preferably, also end stators, each stator being provided with a plurality of magnetic flux producing magnets, preferably of the permanent magnet type. The rotor has a hollow cylindrical configuration and is rotatably disposed such as to form a plurality of magnetic gaps between the inner stator, outer stator and end stators and a plurality of magnetic cores supported by the rotor and provided with appropriate windings, the stator magnetic cores having projections interreacting with corresponding magnets forming the stators.
Claims15
In a dynamoelectric machine having an inner stator comprising a plurality of magnets, an outer stator comprising a plurality of magnets, a pair of end stators comprising a plurality of magnets and a rotor mounted for rotation between said stators, said rotor comprising a first plurality of flat longitudinally elongated substantially rectangular radially disposed thin magnetic cores having electrical windings wound longitudinally therearound and a second plurality of flat longitudinally elongated substantially rectangular radially oriented thin magnetic cores disposed each between consecutive wound magnetic cores, the improvement comprising each of said magnetic cores having at least at an end thereof a first extension integral with said rectangular plate projecting radially toward said outer stator and a plurality of magnets in said outer stator disposed such as to form a radially magnetic gap with said first core extension.
