Hello,
I hope someone can help me (confirming my intuitions here, hopefully):
I am playing with stepper motor design/modification (small steppers ala 3d printers etc.).
I am curious about the electromagnet poles of the stator. Each pole is a serious of paired coils/cores, each a ferromagnetic core wrapped with a coil.
I think those cores are typically extensions of the one-piece-body that is the stator. Is that necessary, or can one have isolated/insulated (from each other) cores for each coil/pole?
I think they can be isolated, and I think I've seen that, but perhaps there's some eddy current consideration or some other reason they need to be connected.
Thanks for any insight.
