A frictionless safety brake actuator includes a fixed component; a movable component; one of the fixed component or the movable component includes a magnetic portion and the other includes a controllable electromagnet; a connection arrangement configured to connect a linkage to the movable component, the linkage is actuatable so as to move a safety brake into frictional engagement with an elevator guide rail; and at least one biasing member arranged to apply a biasing force (FB) to the movable component to bias the movable component towards a first position in which the linkage is actuated; the movable component is moveable against the biasing force (FB) to move between the first position and a second position in which the linkage is not actuated; the fixed component and the movable component together confine a magnetic field between the controllable electromagnet and the magnetic portion in a magnetic circuit.
