Electrical motor control circuit diagrams and electronics projects
Electrical motor control electronics projects with circuit diagrams for stepper motors, dc motor, ac motor using simple and complex technology.
PWM controller and other circuits based on electric motors .
This 12v fan speed controller electronic project is designed using the LTC3600 high efficiency, monolithic synchronous buck regulator whose output is programmed with just one external resistor. This 12v fan speed controller electronic project require few additional electronic components like: a simple operational amplifier , ant NTC and some other common electronic parts .
Input voltage required by this 12v fan speed controller circuit is around 15V DC.
Using this electronic circuit, can be designed a DC motor control using LM317 voltage regulator and some classic electronic components. The c.c. motor control circuit of can be used in control circuits for minidrills.
The electronic circuit makes an internal resistance compensation: when the current through the motor increases, the supply voltage is automatically increased to offset the fall speed.
