I need to benchtest a dc motor drive and the motor and need to fabricate a variable switch or rheostat to give the 0 - 10 vdc input for speed control.
My source voltage is 48 vdc.
I can use resistors to make voltage dividers and pushbuttons to step the voltage incrementally from 1 to 10 volts but I need a smooth sliding type switch like a pot or rheostat but cant figure out how to make it. I know there's something fundamental I'm missing here, it can't be that difficult.
