Current flow controller for DC Motors

[mikebar]

What about an automobile/truck circuit breaker. They reset on their own and normally will handle a bit more amps than rated for a short time.

But if the shaft is locked then you do not want it to keep trying? So a latching relay tied in with the circuit breaker might do the trick.

Uhmmm..
It could work.
I was looking for some more sophisticated solution (like transistors that regulate the current flow right to the thereshold)...

It's called 'foldback' in a regulator circuit.

Totally useless link, but it might get you started...
