Abstract
A regulator for a direct current motor including both current limit and speed feedback paths further includes a speed control circuit for controlling a controllable power supply the output of which governs motor speed. The speed control circuit is designed to provide a desired transfer characteristic having extremely high gain at low frequencies while maintaining a substantially unity gain at higher frequencies to thereby enhance the stability of the motor operation throughout a wide range.
