     BACKGROUND OF THE INVENTION 
     This invention relates to a unique motor generator set. In particular to a motor generator set where in the output of the generator is fed back in series to the electric motor. 
     In the past motor generator sets have been used in automobiles where the electric generated by the generator is sent back to the battery. This only resulted in charging the battery. 
     BRIEF SUMMARY OF THE INVENTION 
     The present invention compromises a motor driven generator where in the output from the generator is fed back directly to the electric motor. In this configuration the voltage from the generator is additive with the voltage from the battery. Therefore there is more electric power directed into the motor that drives the system. Means are also provided (by the use of diodes) to prevent the output power from the generator to flow back to the battery. The output from the generator is in series with the output of the battery. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWING 
       The drawing shows a schematic illustration of the motor generator invention, wherein the output of the generator is fed back in series with the output of the battery to the input of the motor. 
     
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     Referring more particularly to the drawing a battery  10  is connected to the input of an electric motor  11  to energize the motor. Electric motor  11  has a central shaft  12  which drives a generator  13  mounted on central shaft  12 . The output voltage from the generator is fed back to the input of the electric motor  11  through diodes  14  and  15 . Diode  16  is connected between the battery  10  and the motor  11  whereby it prevents the backflow of electricity from the generator  13  to the electric motor  11 . Because the diode  16  allows electricity to flow in only one direction electricity from the generator  13  cannot flow back to the battery  10 . Instead it pairs up with the electricity from the battery  10  and flows to the motor. 
     In operation, electric motor  11  is energized by the battery  10  and rotates generator  13  to produce electric power on output leads  17  and  18 . This power is fed back through diodes  15  and  16  to the input of the electric motor  11 . This is similar to a series hook up with the battery and functions in an additive manner. The benefit of this unique circuitry results in enhanced power to the motor and results in an increased torque from the motor.
