In this paper the combination rotary sealing of ferrofluid and magnetic grease was used for high power electric motor of certain equipment. The pressure capability and the similar friction power formula of it was derived theoretically, that the viscous dissipation power of magnetic grease sealing is approximate proportional to the (2n 1) th rotational speed. The experiments were carried out to verify the combination rotary sealing was theoretically and experimentally feasible. This structure device has been put into practical use.
