It should be noted that the model that is on the website and video are prototypes. The comparison of ball screws to the Cyclone Muscle on the website is not the most comprehensive as it does not cover every aspect and different setups like mentioned.

The Cyclone is a entire linear actuator system, including sensor output, and is significantly lighter than a ball screw drive train that could be deployed in a robot for FRC.

As for the reliability of the cabling it certainly surpasses the requirements of the demands that would be put on the system during a season.

The Cyclone will tolerate 3 degrees of angular misalignment.

Below are the revised specs
The Cyclone's motor currently spec'd to run at 1/3 of stall torque which corresponds to 144 mNm, which at 12 V outputs 165 W of power with about 26 A of current.

As to efficiency, 80% is a better approximation for the efficiency of this version as it includes a gearbox. The Force output for the shipping model is 140 lb = 615 N, P = F*V/e = 165 W.

Then revised specs, 165*0.8/615 = 215 mm/sec


I hope that answered some of the questions.
