hello there....
i need help in something..sorry i am not that expert in electronics..
what i need is something small that can break the circuit when the DC motor is overloaded ( so the motor won t be damaged ) this "thing" has to make the current pass again automatically when the motor is not loaded...
to make my idea clear... i think about the following example:
the power windows system in a car... when i push the button ..the windows goes up ..when it reach the maximum there is either a metal device that break the circuit or a push button... something like that...but i knowt that there is some electronic devices that can do the same thing.. something that senses that the motor is overloaded ( the current is going high) and upon that he breaks the circuit and the motor is safe...
thanks in advance for your help
By the way this "thing" has to be able to handle about 40 amp and 12 v ....
