Spring operated current generator for supplying controlled electric current to a load

摘要

A generator device provides a controlled electric output current to a load, and comprises a source of mechanical energy, a gear train connected to the source, a generator connected to the output of the gear train, and a control circuit connected to the output of the generator to control the output level thereof, the control circuit being such that the feedback generated by the control circuit alone is sufficient to prevent uncontrolled release of the energy in the power source.
