Abstract: This control supplies varying amounts of d-c voltage to a load, such as a motor, to control the speed of the motor, as for example in a battery powered vehicle. A rotating commutator-type switch supplies voltage during portions of each revolution depending upon the position of an adjustable pair of brushes relative to a stationary pair of brushes. An inductance stores energy during the voltage-on intervals and discharges this energy through the motor during the voltage-off intervals in each revolution of the commutator so as to supply a fluctuating voltage to the motor.
