Hello! Im making a controller for a wiper motor which I've modified to be able to pull a little crate uphill. When the crate is loaded it weights about 30 KG. But the wiper motor moves it way too fast, so I'm trying to make a regulator for it with a IL317 and a 3 or 4 2N3055 power transistors. The circuit is not very efficient but right now it is the best I've got. Here is a picture of circuit I've found on internet but I have a couple of questions. I would be using a car battery to power it so the circuit in beginning with a transformer, capacitors and a bridge rectifier would not be used, imagine there are 2 wires there coming from a battery. Now, why are there resistors on the output( on the emmiters), and why are there not any resistors on the base connector of the transistors, i mean should there be a resistor there or am I wrong?
Also Is this circuit correct? Is this diode really necessary? It can carry 6 A
