DC Motor Speed Control

Global Specialties

This circuit allows the user to vary the speed of a DC motor from a stop position to maximum revolutions per motor specification. Integrated circuit oscillates the frequency at 264Hz relative to resistors 1, 2, and 3, variable resistor 1 and capacitor 1. VR1 provides adjustment of duty. If the plus duty is more than the minus duty, the motor will slow down. Frequency will be transmitted through IC to resistor 4 and the base of transistor 1 making TR1 function as adjustment of VR1.
