Abstract: An energy conserving electrical apparatus for driving a load and recovering otherwise wasted electrical energy utilizes an electric motor with field windings on one or more pole members and one or more rotors. During a first time interval whose duration is determined by motor speed, electric current is supplied to the field windings from a first charged battery, the current flowing through electrical switching circuitry to the field windings of the motor to thereby turn the rotor by establishing a magnetic field, as is well known in the motor art. During a second time interval, the duration of which is also determined by motor speed, the rotor's poles confront the poles of the field winding and the switching circuitry disconnects the first battery from the field windings and connects a second discharged battery to the field windings for charging of the second battery.
