I considering trying to rewind this stator out of an Emerson Seabreeze floor model fan. Fan runs but gets hot quickly and smells. I believe it was overheated due to heavy dust buildup.

The stator OHM reading are

 black/green 21 OHMS

black/red 10 OHMS

green/red 11 OHMS

Anyone confirm these readings?

Measuring the magnet wire I get 2 different sizes, 4 coils are .35MM Dia., 2 coils are .5MM Dia.. Is this correct? Wire size I am thinking is 24 gauge and 28 gauge

 

Thanks Ed

Edward, before you attack. What is the smell you are getting. The windings don't looked strained. You need someone familiar with this fan to ring in regarding operating temp. Some motors run very hot,

It smells like burning electrical windings.

no idea on heat readings but I have a roll about & a floor model running daily --I'll check the heat with my hand --do not have any tools to measure temp. Lawrence

Just got around to winding up the coils for this project, Have been putting it off for a few months. 3 paired sets with 2 different gauge wires on each. 169 wraps of the large wire plus 67 of the small. Now to pass them through the less than 3/16" slots without damaging the insulation.

Looking good. Happy to see someone working on a rewind job and sharing the progress.

I have a couple small motors that need this.

Ed, looking at the shape of the
pole projections (triangular),
were you able to fit those
pre-wound coils onto that
stator core?


Almost looks to me that they
may have originally been wound
directly to the core.

I do not think they were wound in place but I really do not know. I removed an entire coil and made the wood bobbins to match the ID size/shape of the original. It looks as if the coil is turned 90 degrees, spread out, passed through the slots, pressed back into shape, then turned back 90 degrees. The longer inside length matches the width of the slot spacing and the short width matches the thickness of the laminations. This entire scenario is what I have worked out in my head theoretically and am hoping it will work in application. If not I will have a seabreeze rollabout fan to part out as I am only going to try this once.
