TIP120 Mosfet Transistor Motor Speed Control Using PWM Signal NE555 Or 7555 Timer IC

Hi, today this post i will show how to control a motor speed.

So basically a motor speed is increase when the input voltage is increase. Suppose if i take a DC 4V motor and if i give it 4 volt then the motor will start with the full speed. Other system is if i give the motor 3 volt then the motor speed will decrease. and if i use more low voltage like 2 volt then the motor rotation speed (RPM) will decrease.

So this simple diagram we are able to control a motor speed very easy method.

For this project we need some little low cost component.:

TIP120 Transistor 1PCS

9V Battery 1 PCS

NE555 Timer IC 1PCS

Or You Can Use NE7555 Timer IC.

10K Veriable Resistor. 1PCS

1uF PF Capacitor 1PCS

1K Ohm Resistor 1PCS

110nF PF Capacitor 1PCS

10nF Capacitor 1PCS

Here is a another easy video for making a pwm motor speed controller.

Many people ask me to make this video veriable voltage control using 2SC5200 Transistor.
