A jam-tolerant electromechanical linear actuator having a contra-rotating axial flux permanent magnet (PM) motor having a first and second rotor shafts in a motor housing. The actuator also includes a first speed reduction mechanism operably coupled to the first rotor shaft and a second speed reduction mechanism operably coupled to the second rotor shaft; a first output shaft operably coupled to a output of the first speed reduction mechanism and a second output shaft operably coupled to an output of the second speed reduction mechanism. The actuator also includes a housing enclosing the PM motor, first speed reduction mechanism and second speed reduction mechanism and a slide mechanism operably coupled to the housing. The slide mechanism permit the housing to slide when the motor housing is fixed to the housing or the motor housing to slide with respect to the housing when the housing is held fixed.
