Im new at this so I hope I don't make the attachments too large or small. I built this circuit and it seems to work for a small DC motor but I need to drive a motor that takes 1 to 6 amps at 27v DC
problems--DC volts shoots up to 40v from27v when Mtr turned on
Pontentiometer---Overheats and smokes
3055 did not get hot but died, 3ohms at all terminals
I probably need a blocking diode somewhere to prevent spikes or feedback
I would like to know how to upgrade circuit to one able to handle a heavier load
I appreciate you reading this ...Thanks....colum
