Purchased a western electric 7901 DC fan

[James Byerly]

Purchased western electric 7901 fan several months ago changed brushes , oil wicks and oscillator grease . It runs real quiet and smooth. However the base of the fan gets very hot after several minutes of running . I assume it’s the resistor coil in the base that’s getting hot . It runs fine on fast speed . Is there an aftermarket coil that I can use to replace it, that doesn’t get so hot ?    Thanks

It should run cool on high,   warm on medium and hot on low.    That is normal.
