    Need help with commercial floor fan please

    Need help with commercial floor fan please

    I took a bit of a punt as to which side would be neutral, however, it probably wouldn't have made that much difference anyhow. Being a commercial fan it may well have sealed bearings. Show a photo inside the end cap.......o_O No idea what you are getting at with query 3. At a guess, I think...

    Need help with commercial floor fan please

    Bearings are not worn by any chance. What will happen there is it may spin freely by hand but when windings are energised, it will pull the rotor and make it rub against the internal pole faces.(called poling) Other than that, all I can think is that the windings have an internal short...
