Elevator systems are described that include a traveling component movable along a guide rail 309 and an overspeed safety system 300. The safety system includes a safety brake 314 connected to an electromechanical actuator 316. A safety brake element 334 of the safety brake is operable to engage with the guide rail to stop the traveling component. The electromechanical actuator includes a frame 310, a first magnetic element operably connected to the safety brake, a second magnetic element movably attached to the frame, and a third magnetic element fixedly attached to the frame. The second magnetic element is movable to urge the first magnetic element from a first position toward a second position. In the second position, the first magnetic element is located proximate the third magnetic element. As the first magnetic element transitions from the first position to the second position, the safety brake element is actuated into engagement with the guide rail.
