i have to use dc gear motor for position control. Is it can possible that by simply couple potentiometer with motor and by taking the voltage response of potentiometer on the oscillograph I can find the mechanical time constant of that motor?
If not, than, whats the issue?
I have a DC Geared Motor.Its just a motor without any related specifications (no Data Sheet) and i dont know its model number. now i have to find out its transfer function how can it be carried out??????????????
