MAGNETIC GOVERNOR DEVICE FOR USE IN AN ELEVATOR SYSTEM

摘要

An exemplary elevator governor device includes an elongated governor member that is configured to remain stationary in a fixed position within an elevator hoistway. The elongated governor member includes an electrically conductive material. A plurality of magnets are configured to be supported for movement with an elevator car that moves within the hoistway. The magnets surround the elongated governor member and are configured to induce eddy currents in the electrically conductive material as the magnets move relative to the elongated governor member responsive to movement of the elevator car within the hoistway. The induced eddy currents result in a force that resists movement of the magnets relative to the elongated governor member. A plurality of conductive plates are adjacent the magnets for directing magnetic flux from the magnets into the conductive material of the elongated governor member.
