I know that current brushless motors, have a non rotating core made of copper coils, with permanent magnets on the outside rotating around it, and eventually connected to a shaft. But i was wondering, if it was possible to make the exact opposite ?
I mean having a rotating core made of magnets around a shaft, with non rotating coils around it. Would it work? Hallback arrays of magnets would still work ?
I mean, phases are the same, and Magnetic field are not unidirectional. I don't see why it couldn't.
Thank you in advance.
