A system () includes one or more sensors configured for acquiring data related to operational conditions of a motor actuator (), a processor () configured for analyzing the data to determine a status of the motor actuator (), and memory () for storing data representative of the operational conditions. A status indicator is generated based on the analysis of the operational conditions, for example to represent system capabilities, normal operating modes, and failure modes of the motor actuator (). The system () can be configured to communicate the status indicator to a user interface () or higher-level controller ().

Actuator diagnostics and prognostics

An actuator system includes a housing with a screw shaft extending along a longitudinal axis. The stator component of an electric motor is coupled to the housing, with a rotor extending along the longitudinal axis. A thrust tube is engaged with the screw shaft, for example with a nut assembly configured to convert rotational motion of the rotor into linear motion of the thrust tube. A modular cooling assembly is selectively coupled to the exterior surface of the actuator housing, and configured to dissipate heat.
