Remember, field coil alternators have contacting parts. They have to have carbon brushes and rails to transmit the power to the rotor coils. These can wear out, become fouled with carbon or break.
Actually, the regulator is often electro-mechanical too. Kind of like a set of points. They can fail but can usually be fixed.
On a magnetic alternator, there are no touching parts.
I'm pretty sure field coil ones are cheaper to make. A magentic rotor often costs more than a stator. RARE earth magnets.
So neither is particularly better than the other in my experience. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”
