Abstract
A frictionless electronic safety actuator () for use in an elevator system, which includes at least one electromagnet (), and a magnetic plate () attached to a connection arrangement (). The connection arrangement () is configured to connect the magnetic plate () to a linkage () that is actuatable so as to move a safety brake () into frictional engagement with an elevator guide rail (). The at least one electromagnet () is operable to selectively produce a magnetic force which acts upon the magnetic plate () to displace the magnetic plate () and thereby move the connection arrangement () to actuate the linkage () without the magnetic plate () coming into frictional engagement with the elevator guide rail ().
