Abstract
The principles and applications of dc motors, ac induction motors, stepper motors, solenoid actuators, and micromotors used in process automation are discussed. Their operating principles, characteristics control approaches are outlined. Several output devices typically used in industrial applications are defined. Microactuators, new members of the output equipment family, are also introduced. Several real industrial actuator products and their specifications are described. Computer-based displays and data loggers are introduced and and important technical trends are pointed out. It is clear that future applications of output devices will focus on the development of industrial actuators of smaller size, lighter weight, higher output power and torque, and better static and dynamic characteristics. Novel mechanisms for force generation and more sophisticated machining technique to facilitate the realization of these goals are expected.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
