Ac Motor Speed Control Circuit

This BT136 Triac based 230 volt AC motor speed control circuit is designed for adjusting the speed of an electrical motor in your homes like drilling motor or dress stitching machine motor.

The speed of the electric motor adjusted by using the Preset pot on the circuit diagram.

so in this article, I’m going to explain Detailed about How to control the electric motor speed control using Triac based circuit. The specialty of this circuit is very few numbers of components are used to control the power Ac motors.

The motor speed control circuit working based on the Triac of BT136. Adjusting the 500k pot will increase or decrease the running speed of the electric motor.

The Inductor used in the circuit is an optional you can use or avoid it ( you can also take the direct neutral without the inductor ).
