Very grateful to have found this forum. Thanks for any help you can provide.
I would like to run a motorized wheel at 120 rpm synced to an IR signal -- basically an on/off signal, and one ON pulse per revolution.
I probably can get by with a potentiometer to adjust the rotor to approximately 120 RPM and then rely on the pulse to finally sync the rotor speed.
Since the rotor might start up out of positional phase, there might have to be some way of adjusting it to sync up. But then it should remain stable in position as well as RPM.
To give an idea of the size of this motorized project for circuit output power requirements, the diameter of the wheel will be probably 4" (100 mm) and would weigh about 1 ounce (28 g.). I hope it would just spin on the motor bearings, like a muffin fan.
I'd like help with a driver circuit, and a possible suggestion for a motor -- surplus is fine.
I've built breadboard circuits before, and printed circuit kits, (and once way back in 1983, an LNW-80 computer from bare boards and surplus IC's). I have a multimeter, but that's all for test equipment.
Thank you if you can help.
