Beautiful Dc Motor Controller Circuit Diagram

Dc motor speed controller circuit.

Dc motor controller circuit diagram. The switch is to change the direction of rotation of motor. The user can experiment with it for a right one. 3 easy to build speed controller circuits for dc motors are presented here one using mosfet irf540 second using ic 555 and the third concept with ic 556 featuring torque processing.

The timer chip which applied in this circuit will be an nmos dual timer oscillator ne556. 100k 220k preset or pot. Circuit components 9v power supply.

Complete circuit diagram for the motor controller along with the parts list has been included here. On the other hand when the wiper arm of vr1 is at the bottom position c1 charges through r1 r2 and vr1 and discharges via r2. The pot here is used to adjust the speed of motor.

Therefore the motor speed is slow. When the wiper arm of potmeter vr1 is in top position capacitor c1 charges through r1 r2 and d1 and produces a pulse train at the output of ic1 with long negative and short positive pulse widths. Then check out this outstanding single chip pwm motor speed controller circuit that will give you a complete 360 degrees of continuously varying motor speed control right.

Are you fed up with ordinary pwm circuits which do not provide perfect dc motor speed control especially at lower speeds. A circuit which enables a user to linearly control the speed of a connected motor by rotating an attached potentiometer is called a motor speed controller circuit. This timer ic has two 555 timers in a single 14 pin ic package.

The circuit applies two oscillators timers which are connected as a pulse width modulator pwm. The circuit is connected in breadboard as per the dc motor speed control circuit diagram shown above. The capacitor here must not of a fixed value.
