Hi, I have some general questions please if you can help.
can anyone help me design a starter-motor controller and using a 12 volt car battery.(for a small go-kart) . Or give me some tips as to whats involved as Im trying to learn from doing these projects.. My new/limited experience is yesterday soldering up a kit to handle a motor up to 1 amp.
I have Been running a motor from a windscreen wiper off this little experiment using a 12 volt 0.39 amp battery. It gets extremely hot , the heatsink bolted to the transistor. Using some kind of pulse modulation to control speed. Is the transistor likly to be turnining on and off furiously to controll speed ?
So I am guessing that a speed controller is more complicated than simply controlling the amount of resistance. Which I previously thought was all that had to be done. Also the battery specs of the little battery from Jaycar, it says initial current 0.39 amps. Does this mean that 0.39 Amps is all I can pull from that battery? Does having a pretty heafty motor such as the windscreen wiper pull any more amps ?
Regards,
Mike.
