Hi everyone.
I have got a shaded-pole motor and I have extracted the rotor to check one thing.
I understood that the squirrel caged rotor based its functioning in a alternating magnetic field that induces a current in a conductive bars, wich creates an another magnetic field and start the movement. But I thought that that conductive bars have to be isolated. But not. I have checked them with the DMM and the hole rotor is in short. The shaft, the block, the bars...
So, what´s the point of put conductive bars if the hole rotor is conductive metal? The induced current can travel by the whole piece.
Thank you.
Kind regards
