Abstract
A motor is to be driven from a source of high-voltage electric energy, and a generator is adapted to produce a lower-voltage electric energy. A hydraulic stepdown arrangement is provided which drives the generator from the motor and which includes at least one closed hydraulic circuit having a conduit loop, a plurality of hydraulic pumps of successively greater capacity which are driven by the motor, and a fluid-driven rotor coupled with the generator for driving the same. The rotor receives the combined fluid output of the hydraulic pumps. Other drive systems are also disclosed.
