Abstract: A linear actuator system having an actuator housing, a motor assembly, a screw shaft, a thrust tube, and a nut assembly. The nut assembly is engaged with the screw shaft and directly coupled with the thrust tube. The nut assembly can define a mechanical fitting for direct physical engagement between the thrust tube and the nut assembly, absent additional load bearing components intervening therebetween. The nut assembly is configured to convert rotational motion of the rotor about the longitudinal axis to linear motion of the thrust tube along the longitudinal axis. A cooling loop can be at least partially embedded, potted or seated within the actuator housing, with a thermally conductive material disposed at least partially about the cooling loop to conduct heat from the actuator housing.

Abstract: The present disclosure relates to a manual override tool for an electric actuator. The manual override tool includes an accessible first end, a shaft operably connected with the first end and is movable in a linear direction and is rotatable, and a plurality of gear teeth on the shaft. The accessible first end is used to engage and disengage the plurality of gear teeth with a plurality of notches provided on an interior rotor of the electric actuator, such that the accessible first end may be used to manually operate the electric actuator.

Abstract: A linear actuator and housing assembly may be used to increase motor performance and dissipate excess thermal energy. One embodiment relates to an actuator housing and an electric motor coupled to the actuator housing, where the electric motor is disposed within the actuator housing such that there is a close proximity between the actuator housing and the motor. A linear actuator assembly may be operably coupled to the electric motor, where the linear actuator assembly is disposed within the actuator housing and a thermally conductive material is disposed between the actuator housing and motor.
