ABSTRACT:
A system for controlling the speed of a direct current motor. The system employs a pair of breaker points for opening and closing the circuit containing the motor. By varying the frequency of contact between the breaker points and the period of time the points are in contact, different pulsations of current are transmitted to the motor to regulate its speed.
