Usual, we just enter the voltage and DC current source to the DC motor, Makes motor can be rotated. If will modify or regulate the speed in rotation of the motor. Wewill need to enter the voltage look into pulses or periodically. Which will makes the average voltage at output is different. By the pulse voltage is high frequency will has the average voltage than the low frequency pulse. The same with the pulse has over duty cycle value, it will has the average pressure much than low duty cycle value. The working principle. The average voltage will be supplied …

The temperature controlled on off relay circuit,main ideals is thermistor will change its resistance.IC1-LM393 to bias transistor to drive relay works.
This is speed motor controller circuit of 12V DC motor. as SCR DC motor speed control circuit using IC-4081 CMOS. You can adjust the speed of rotation
If you get into trouble about the heat of notebook. Today I begs for to advise the way enhances the speed of the electric fan with Fan Speed over Ride Switch circuit. Normally the electric fan will begin to turn when 60 c temperatures by have voltage feed 2.0 v. If still hot again enhance voltage go to 2.1,2.2,2.3….3.0V. At 80c circuit temperatures board circuit send the maximum score only. But temperature still go up again arrive at 100c until shutdown by oneself finally. When try wire for electricity usb 5V as a result make the electric fan turns well. …
This is PWM Speed DC motor Rotation circuit. It can Forard-Reverse and Regenerative Braking function. By this circuit use a signal PWM control the speed of DC 12V motor with Power mosfet IRF150. The relay RY1 use control Reverse with the digital alarm , change , Q10. The Relay RY2 work be , function brake resistor. By control Run or stop with the digital alarm with . The F1 , use protect through the circuit. The D1 use for protect current turn back from DC Motor. The detail is other , please see in the circuit. Note : PWM Control …
