Use MC14093 pulse width modulation circuit diagram/ schematics

The pulse width modulation circuit diagram electronic project is very simple and require few external electronic parts. Speed ​​adjustable 0 – MAX. Maximum speed of 2/3 of the supply voltage. Can be used in this project, the supply voltage can be 3 to 18volt. MC14093 CMOS type MC14011 IC can be directly interchangeable with the CMOS IC. Input pins 8,9,12 and 13, need to be connected to GND. Or “V +”. Output pins 10 and 11 unconnected. And display elements, the maximum current consumption of about 220 mA maximum use of small motors.

P1potentiometer can multi-turn, if you need a specific rpm. The transistor Q1 can be a IRF513, IRFZ42I IRF620 IRF511 type or, in order to minimize RFI (radio frequency interference), Q1 gate beads. Some require faster switching motors may require an appropriate specification of the Schottky diode.
