Good evening, Before I start, I'm sorry if this is in the wrong forum, I wasn't sure where to post such a question. I have an car alternator which I'm going to be experimenting with to generate electricity from the wind. It's a GM Valeo model, possibly taken out of a Vauxhall. Right now it's disassembled and I need to take the rotor apart since I'm planning on replacing the coil inside with a ring permanent magnet. I've also come up with an idea of using multiple magnets and placing them on the inner-side of the "claws" with different poles (N, S, N, S, etc) however I'm failing to see if that will be good enough. If anyone knows how to take a rotor apart, I'd greatly appreciate your help. I can't find anything to take off to make it come apart. Please note this is my first time doing this. Also, if anyone has anything to add to improve the output of the alternator when it's been re-assembled, please post it here! I have some images here of the rotor here; A B C Thanks! Owen.
