    Abstract: A d.c. generator is connected in series opposed to the polarity of a d.c. power source supplying a d.c. drive motor. The generator is part of a motor-generator set, the motor of which is supplied from the power source connected to the motor. A generator field control means varies the field produced by at least one of the generator windings in order to change the effective voltage output. When the generator voltage is exactly equal to the d.c. voltage supply, no voltage is applied across the drive motor. As the field of the generator is reduced, the drive motor is supplied greater voltage until the full voltage of the d.c. power source is supplied when the generator has zero field applied. Additional voltage may be applied across the drive motor by reversing and increasing the reversed field on the generator. The drive motor may be reversed in direction from standstill by increasing the generator field so that a reverse voltage is applied across the d.c. motor.

    Abstract: A switch for speed control of an electric motor driven vehicle employs a combination of resistance switching, field weakening and voltage switching. A mechanical switch assembly has a speed switch and a voltage switch that are interconnected so that the voltage switch provides 36 volts when the speed switch is in neutral and fifth speed position and provides 18 volts when the speed switch is in first through fourth speed positions. The speed switch has an operator controlled rotor arm that successively engages a neutral contact and five driving speed contacts so that varying resistance is inserted in circuit with the motor armature in the first two speed positions and no external resistance is employed in the third and fifth speed positions. The motor field comprises pairs of first and second oppositely disposed series wound coils with the pairs of coils all connected and energized in series in all but the fourth speed position. In the fourth speed position one pair of oppositely disposed field coils is completely disconnected while the other pair is energized to provide a higher speed at the lower voltage and a better transition between low and high voltage driving speeds.
