Elevator system governors include a traction pulley having an engagement surface and a cable wound about the traction pulley that is configured to travel along the cable. An electromechanical locking mechanism is configured to selectively engage with the traction pulley to cause operation of a safety brake of an elevator system. The locking mechanism includes a hub assembly having inner and outer engagement hubs. The inner hub has an actuator connector connectable to a safety linkage and the outer hub has an engagement surface for selectively engaging with the engagement surface of the traction pulley. An actuator is configured to selectively apply force to the outer engagement hub into engagement such that the engagement surface of the outer engagement hub and the engagement surface of the traction pulley are engaged, and to cause rotation of the inner engagement hub.
