but the motors were junk
Why were the motors junk? Induction motors usually last forever unless their windings burn out or their bearings seize up.
They were 20+ years old and didn't run when I wired them up, I didn't bother opening them to check why I just sent them to scrap. It appeared all the insides were coated in nasty sticky dust but can't say for sure that's why they seized. They were really crusty, not worth investing time into. One of them started smoking when I tried to start it
They're not induction, they're series wound universal motors that you find in blenders and line powered power tools.
Why do you keep taking stuff apart? I remember now, you're the guy who keeps turning useful stuff into scrap. What on earth are you going to do with bushings and shafts from blower motors? I'm not suggesting these were particularly high value items or anything to begin with but disassembled they are scrap value. You seem obsessed with tearing stuff apart into completely useless bits.
Are you sure? I took apart a few and didn't see any magnets, watched some yt teardowns too and couldn't see magnets.
https://en.wikipedia.org/wiki/Universal_motor^ says it uses electromagnet, I don't understand.. electromagnet isn't the same as a permanent magnet
Why do I keep taking stuff apart? Ahh that age old question
sounds like something my mom would ask hehe
"you're the guy who keeps turning useful stuff into scrap"
lmao
Bushings and shafts are useless to you, but very useful to me. I'm building out a metal shop for custom fabrication. I have benders, cutters, hundreds of pounds of stock steel, 100 ton hydraulic press under construction, plasma cutter, mig welder, stick welder, custom propane forge, lots of AC / DC motors, etc etc. If I want to build something, bushings and shafts are very useful. A 40 year old blower caked in filthy dust won't sell on kijiji for $20 (tried before disassembly / scrap).
