I have two 12V cordless drill motors I am intending on using in a robot and need to find a suitable controller. I have measured the stall current using a shunt and my multimeter with clamped shaft and the highest reading I got was 43A, but I found a datasheet that listed the stall as 60A (perhaps I didn’t see that current as it was present for too short a time for my cheap meter, or my wires to small?). I’ll be running the motors at 12v nominal. This is not a combat robot and will be under autonomous control.
Will the 18v15 be sufficient? Can I rely on current limiting to use a different driver?
