If a low viscosity oil like a SAE 10 is used it's not really a problem.
Try it some time. Put an old fan motor or some open frame capacitor start/run type of motor in a coffee can of light oil and let it rip.
Unless it's a pathetically low powered shaded pole type it won't have any problems at all. To be honest try it with a low duty cycle motor like one from a garage door opener in a larger bucket of oil. The thing will run continuous duty without a problem as long as it can get the oil to circulate around the windings and core.![Cool :cool: :cool:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
