Abstract: A seal assembly includes a stator attached to a housing and a rotor attached to a shaft. A static sealing member is attacked to the stator presenting a contact with the rotor at stand-still. An electromagnetic is attached to the stator at a distance from an end of the static sealing member.

The electromagnet is controlled by a control system for controlling the equipment in which the bearing isolator is used. To deactivate the static sealing member during shaft rotation, the bearing isolator may have its own control system with a sensor to indicate if the shaft is rotating. As the shaft rotates, contaminants are expelled through gaps between the stator and the rotor.
