ABSTRACT:
A dynamoelectric machine comprising a plurality of single functional modular units mounted end to end on a common output shaft. Each individual unit comprises a rotor consisting of a single cylindrical coil or winding having its axis at a right angle to the shaft longitudinal axis, a pair of outer stators preferably in the form of permanent magnets and two pairs of end stators, each pair of end stators on one side of the coil. Each modular unit, when operating as a DC unit, is provided with its own commutator consisting of a split ring and, when functioning in a motor mode, all the commutator brushes of an assembly of modular units are connected in parallel across a common DC power supply. When operating in a generator mode, all the modular units are connected to a common lead. Output power can be tailored by mounting an appropriate number of modular units end to end in a housing.
