A frictionless safety brake actuator, for use in an elevator system, includes at least two stators; a magnet array positioned between the stators; a linkage attached to the magnet array; and a biasing arrangement. The linkage is actuatable to move a safety brake into frictional engagement with an elevator guide rail. The magnet array is moveable between a first position in which the linkage is actuated and a second position in which the linkage is not actuated. The biasing arrangement is arranged to bias the magnet array towards the first position. The magnet array includes a first magnet set and a second magnet set which comprise at least one magnet each and at least three magnets in total. The magnet(s) of the first magnet set is/are arranged alternately with the magnet(s) of the second magnet set in a stack.
