Abstract:
1. A linear actuator and housing assembly, comprising: an actuator housing; an electric servo motor having a motor housing coupled to the actuator housing, wherein the electric servo motor is disposed within the actuator housing such that there is a close proximity between the actuator housing and the motor housing; a linear actuator assembly operably coupled to the electric servo motor, wherein the linear actuator assembly is disposed within said actuator housing; and a thermally conductive material disposed between said actuator housing and said electric servo motor, the thermally conductive material having high thermal conductivity to transfer heat from the electric servo motor and linear actuator assembly to the actuator housing for dissipation of the heat therefrom; wherein the thermally conductive material fills all areas between the electric servo motor housing and the actuator housing including an area disposed around an outer peripheral surface of the motor housing and recess areas at a proximal end and a distal end of the motor housing to promote conduction of the heat away from the linear actuator assembly and the electric servo motor toward the actuator housing; and wherein substantially no air is present between the electric servo motor housing and the actuator housing.
