# Electric style motor speed control [closed]

I was just wondering how I would go about making a pedal that controls the speed of a motor. It would also have to include reverse motor capability. My tech book at school already has a circuit for reversing motor direction but might not be compatible with what you might come up with. Thanks.

EDIT: oh, also what would I use to limit the amount of electricity that can go through a wire.

• What sort of motor is it (AC, DC, brushed, brushless etc.) what voltage does it run on, and what is the maximum current and/or power that you want it to draw? Can you show or describe to us your reversing circuit? – Bruce Abbott Mar 27 '15 at 22:57
• Don't have motor yet but would have to be big enough to power electric car/go cart. As for limiting the current I don't know but my source of power will be variable ie. solar panel. And here is the circuit I talked about. It starts with the dc source loop and on the left there is a push to make switch. When pushed, it activates a relay switch.

• This is a pretty dangerous and high power project, if it's for motors for powering a go cart. Perhaps you should find someone nearby that can help you with the project, especially for the high power aspects – KyranF Mar 27 '15 at 23:15
• I guess this project would be basically a car battery or two with two big 12V motors (perhaps salvaged from an electric wheelchair, and then gears down for speed rather than torque) using some high power 80 Amp ESC (electronic speed control) for each motor to drive them. A pedal can be connected to a potentiometer to give a variable output voltage, which can sometimes go directly into a ESC to vary the output speed. – KyranF Mar 27 '15 at 23:41
• KyranF - how would you go about connecting the esc to a pontentiometer? – TheDude Alex Nuzum Mar 28 '15 at 0:46
