why do car alternators do not use permanent magnets?
I'm an electrical engineering student and i am wondering why do car alternators do not use permanent magnets? , i thought the purpose was to generate power strictly form mechanical motion with the input of any type of electrical energy(exiter) and if they do can you tell me if my alternator uses permanent magnets. I have a a2t13977.i do not know how they do things in the automotive world, so that is why i am asking.DISCLAIMER:NO NEGATIVE REMARKS,REDUNDANT ANSWERS,CRITICISM OR IRRELEVANT ANSWERS OR I WILL BLOCK YOU.
Though starters may have them, they are not under the constant use as the alternator is. The permanent magnets used in starters are of a ceramic material and will not conduct a constant charge/output that a copper coil produces. This is only my guess and not a stated fact.
