Took apart pool pump motor - what is the armiture actually madeup of (no wires, no magnets)?
Thank Nikola Tesla. For polyphase induction motors, they can start
themselves. For single phase motors, there is a starting winding that
"fakes" rotating field until the rotor is up to speed, then cuts out.
They are pretty non-obvious in their operation.
