A frictionless electronic safety actuator (200) for use in an elevator system, which comprises at least one electromagnet (210, 212), and a magnetic plate (220) attached to a connection arrangement (290). The connection arrangement (290) is configured to connect the magnetic plate (220) to a linkage (80) that is actuatable so as to move a safety brake (24) into frictional engagement with an elevator guide rail (20). The at least one electromagnet (210, 212) is operable to selectively produce a magnetic force which acts upon the magnetic plate (220) to displace the magnetic plate (220) and thereby move the connection arrangement (290) to actuate the linkage (80) without the magnetic plate (220) coming into frictional engagement with the elevator guide rail (20). The at least one electromagnet (210, 212) is configured to move the magnetic plate (220) and the connection arrangement (290) in a vertical direction to directly displace the linkage (80) in the vertical direction. A pair of electromagnets (210, 212) are positioned vertically displaced so as to selectively produce magnetic forces to displace the magnetic plate (220) vertically between the two electromagnets (210, 210) so as to actuate the linkage (80).
