ABSTRACT:
An electrical machine system for driving a load and for providing power generating functions is made up of at least two electrical machines and a clutch controllable transmission. The two electrical machines are operatively connected by a clutch controllable transmission to obtain the following functions: 1.) the electrical machines can either drive the load individually or together; 2.) one of the electrical machines can be driven by the load feedback for power regeneration; and 3.) one of the electrical machines can be driven by an external power input to drive the other electrical machine as a generator for charging the battery or supply power to other loads. To achieve these functions, the transmission components can be in the form of one-directional or speed-responsive clutches, while the two electrical machines can be in the form either of two separate motor/generators, or dual windings of a single armature/field generator structure.
