DC Motor Reversing with Relay A DC motor reversing circuit using non latching push button switches. Relays control forward, stop and reverse action, and the motor cannot be switched from forward to reverse unless the stop switch is pressed first……

Pulse Width Modulation DC Motor Control by 4011 Often, people attempt to control DC motors with a variable resistor or variable resistor connected to a transistor. While the latter approach works well, it generates heat and hence wastes power….

Touch Motor Control by SCR and Schmitt Trigger This circuit designs for control DC Motor 12Volt. By use the touch once Motor as a result turn go to once. When use a finger touches the metal makes Schmitt Trigger Circuit take a signal from Oscillator Circuit and make a signal goes out Trig SCR Bias Current the DC Motor 12V then turn follow want…..

Simple DC Motor Control circuit was built to operate a small motor used for opening and closing a pair of curtains. As an advantage over automatic closing and opening systems,….

DC Motor Control with TIP31 Here, S1 and S2 are normally open , push to close, press button switches. The diodes can be red or green and are there only to indicate direction. You may need to alter the TIP31 transistors depending on the motor being used. Remember, running under load draws more current. This circuit was built to operate a small motor used for opening and closing a pair of curtains. ….

PWM D.C. motor drive Low loss speed control By 4093 This circuit is a very compact switching regulator for small DC motors. I use it for my small printed circuit board drill
(18 Volt, 1.5 Amp), but it is suitable for many other applications (e.g. 12V DC halogen dimmer)….
