초록

This paper presents the magnetic flux distributions of a ferrofluid seal at the sealing gap between the pole pieces and the rotating shaft. The optimized shape of pole pieces has been determined by using the computer simulations. The computed results indicate that the sloped pole piece of 27$^{\circ}$ shows good flux distributions compared with that of the conventional flat pole pieces and may reduce frictional heats due to a reduced surface contact areas of magnetic fluids.
