Electromagnetic coupling with a slider layer

An exemplary electromagnetic coupling device includes an electromagnet and a vane member that is selectively magnetically coupled with the electromagnet. A non-magnetic slider layer is supported on one of the electromagnet or the vane member such that the slider layer is between the electromagnet an...

Beschreibung
Zusammenfassung:	An exemplary electromagnetic coupling device includes an electromagnet and a vane member that is selectively magnetically coupled with the electromagnet. A non-magnetic slider layer is supported on one of the electromagnet or the vane member such that the slider layer is between the electromagnet and the vane member. The slider layer maintains a spacing between the electromagnet and the vane member. In a disclosed example, the electromagnetic coupling device is used for coupling an elevator car door to a hoistway door for moving the doors in unison between open and closed positions.
