Dc Motor Speed Controller Circuit

This motor speed controller uses a single ic lm1014 to control the speed of a dc motor.

Dc motor speed controller circuit.

Dc motor may be a purely inductive load so if you would like to regulate the speed of the dc motor then we ve to upper lower the voltage for higher lower speeds. A pwm circuit based on timer ne555 is the heart of this circuit. An external variable dc voltage source is effectively translated into a varying pwm signal. A simple dc motor controller circuit using ne555 is shown here.

It senses the increase in the motor current when the rotation of the motor slows down due to a load. P1 potentiometer varies the speed of the motor. It is basically a pwm pulse width modulated motor driver that incorporates two separate stages for the generation of the pulses. Therefore the motor speed is slow.

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. 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. Dc motor speed controller circuit. The proposed circuit can be considered almost a perfect dc motor speed controller.

Mainly we are getting to find out how the circuit works and what s about the pwm signal. The ic then increases the motor voltage so that the original speed is recovered. Dc motor speed controller circuit. Many dc motor speed control circuits have been published here but this is the first one using ne555 timer ic.

In addition to controlling the motors speed its direction of rotation can be also changed using this circuit. But in practically higher voltage and lower voltage isn t that sort of possible so during this case we use another sort of method which is named pwm better.
