thanks for your advice, i dont need to run it from batteries, i can use a DC power supply directly from AC.. so if i only want maximum 1/4 of the power of the potential power of the motor, can i run a 30A, 12V power supply?
sorry, i only have a pretty limited knowledge of ohms law..
thanks again
Hi,
I have a 60A, 24V DC geared, brushed motor taken off an electric wheelchair that i want to use to help my friend build a pottery wheel.
to this end, all i need it to do is rotate with variable speed (controlled by a foot pedal) in the one direction, so i think a proper digital motor driver...
function generator
i found this circuit on the internet that uses the 741 IC op amp which looks like it might be helpful..
a couple of questions about it though..
can anyone tell me the frequency range of the output? what would i need to change in order to make the range from 1Hz to 1kHz...
waveform generator ic
Hi,
i was just wondering if someone could help me with something im trying to build..
i am looking for a simple circuit diagram for a waveform generator, battery powered, can switch between sine/triangle/square waves and is variable from 1Hz to about 1kHz - or something...
