Abstract
This disclosure describes a DC motor system that is capable of extracting electrical power to do useful work while the DC motor is in operation. The present invention relates to a DC motor configured to have a plurality of brushes which enables two of the plurality of brushes to serve as input power brushes and at least one of the plurality of brushes to serve as power extraction brush to extract electrical power from the DC motor. The extraction of electrical power is achieved by using a power extraction circuit which switches the extracted power between two different energy storage devices. The energy storage device includes and not limited to capacitors and batteries.
