A frictionless safety brake actuator for use in an elevator system, including a triggering component moveable between a first position and a second position; a reset component movable between a normal operation position and a reset position; a biasing arrangement arranged to apply a biasing force (FB) to the triggering component to bias the triggering component away from the reset component towards the first position; wherein one of the triggering component or the reset component includes a magnetic material, and the other of the triggering component or the reset component includes an electromagnet, wherein the electromagnet is operable to selectively contribute to a magnetic force (FR) which acts upon the magnetic material; and a reset driver arranged to drive movement of the reset component between the normal operation position and the reset position independently of movement of the triggering component.
