[Oeva-list] EV Conversion Source

A previous poster mentioned getting some material from Bob's Metals and that motors are available there. I had to be in Portland  today and went by Bob's Metals and they do have several bins with mainly AC motors in them, but you can sort through them if you know what you are looking for. The man I talked to knew about Nev, I hope I have it spelled correctly, and said he bought some plate aluminum. 

He indicated  that he might have a forklift motor and would have to look to see if it is still on the ground. He said he would start to pull out the electric motors from the forklifts as it sounded like enough people might be interested in buying them to be worth it. He had some motors from welder generators as well. Also, there were some industrial DC motors there and looked huge and heavy. Maybe someone could comment on these motors as to the possibilities to use them and maybe what voltage ranges they might have. I think that this might be a good source for someone on a limited budget for motors. Hope this helps. Dan Eyk
