	What would be the solution regarding a DC motor getting pointed spark on the commutator and getting tripped due to a short circuit?

	Is the commutator showing any other signs of damage? You've not given us much to go on. __________________ The reports of my death are greatly exaggerated.

	It sounds as though at least one of the windings has a short circuit fault on it. A 12VDC motor rated at 5W might warrant replacement with a new one from the local model shop. A 3300VDC motor rated at 5MW might warrant a site visit from the manufacture's technicians with some of their test gear before taking their advice. Size is important - especially if one wants the wallpaper to stay up! __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856
