Motor speed controler
The PWM circuit is quite simple to build,on a piece of vero board,use a 14 pin IC Socket each side of the breaks in the rails.you can connect pins 2,12,9
&8 together,(they don't go anywhere else,the rest of the components are easily fitted,working you way to the Mosfets.You can use either 1 or 2 FETS,depending how much ampage you want to draw.I use two IRFZ48N,because I run at 30 amp continuous,you will also need a meaty heat sink and probably a fan.you can connect VR1 to opperate remotely if you wish.I've been running mine for allmost a year with no problems. I have a channel on Youtube,search for terryblount163 you will see why I need a 30amp, PWM.good luck Terry
