De-ponging a motor

There are people called "French Polishers" whose job is to repair such damage.

Or rubbing with a soft cloth impregnated with a hint of ethanol would sort a wine glass ring.

Well I tried dunking the motor in isopropanol and giving it a good shoogle and brushing with a paint brush to loosen anything on the surface. The solvent came away considerably dirtier and thankfully there was no sign of the shellac dissolving.

After a blow dry though it didn’t really smell significantly better. With nothing left to lose before binning it I just washed the whole motor in hot soapy water followed by a rinse in alcohol and another blow dry.

This time the smell was very significantly reduced and after oiling the bearings I reassembled it. To mask the lingering smell I worked on the “fight fire with fire” principle and ground a handful of coriander seeds.

It’s probably never going to be used for grinding coffee so smelling of Indian spices is fine with me. ;-)

i have one for coffee and another for spices.

Could it have a shorted turn? That wouldn't necessarily stop it working, but it would push up the power consumption and have that shorted turn overheating. Check its power consumption is what it should be.

Why? It works. It does all I need of it now. If it subsequently stops working or starts getting smelly again I’ll be binning it.
