I have yj61 series motor. Something like this
It's rated AC120V 60Hz 3000RPM and was damaged by accidental connection to 220v mains. I can't find suitable spare motor, so I have to rewind this one anyway.
And if I have to rewind it, then I'm curious if it is possible to change its winding to make it 3000rpm at 220V 50Hz, to remove 220v-110v transformer from the setup.
Could you provide me with book reference or any other material which explains how to calculate coil parameters for shaded pole motors? Ready to use answers (like "use doubled number of turns with a half-diameter wire") are welcome too.
