<p>A drive system for returning power to at least one power storage device (5) and at least one motor (10) intermittently energized and de-energized through coupling to the at least one power storage device (5). The drive having at least one weighted drive member (15) coupled to the motor (10). The system also includes a drive unit coupled to the at least one weighted drive member (15) such that the motor (10) drives the at least one weighted drive member (15) which in turn drives the drive train (25) wherein the at least one weighted drive member (15) is disengaged from the drive train (25). The motor can remain in an energized state or become de-energized and the energy recovery device (35) can continue to return energy to the power storage device (5) so long as the weighted drive member (15) is driven.</p> |
