Hey guys,
This is my first time posting on here, been lurking on and off for a few months on this great site. My electrical experience is pretty basic and I'm looking for new and challenging projects to keep myself busy. Here is my latest idea I would like to try...
I have a PWM signal supply and I'm looking at running 4 electric DC weatherproof rated motors. They will run around 55rpm consistently for up to 12 hours a day outdoors. I have read some on 555 timers and mosfets but am not really sure where I need to start searching. The kicker is that each motor will have a slightly different load on it, anywhere from 7-15ft. lbs. and they all have to run EXACTLY the same speed. I'm assuming that I will need to find someway to run a tach on each motor connected to a controller that will let each individual motor make adjustments to run at the speed the PWM is calling for. Any help would be appreciated!
