Electric Rotary Actuator - R SERIES

The R Series compact electric rotary actuator was specifically designed for small ball valves and dampers. This heavy-duty reversing actuator develops 100 lb·in torque and rotates form 0 to 90 in 2.5 seconds. The spur gear drive train has been designed for severe applications and, as in all ICI actuators, can with stand stall conditions without suffering gear failure.Electric Actuator The heavy-duty aluminum enclosure meets NEMA 4 specifications and has a thermally bonded ultraviolet-resistant polyester powder coating that not only enhances its appearance but also is a tough corrosion resistant coating.

Standard equipment includes 115Vac-1ph motor with thermal overload protection, stainless steel fasteners, captive cover screws and 300 series stainless steel output drive, spring friction brake, non-declutching manual override and position indicator.

40 corrections per second

2007-12-06 12:27:37 by iamlucky13

What they mean when they say that, is that the computer reads the input states 40 times per second. Each time it reads the input states, it compares the values to expected values, then uses an algorithm to determine the desired control states. We now have computers with processing power to do it hundreds of thousands of times per second...much much faster than the response times of the systems involved and sometimes faster than any actuators can actually respond.
The algorithms are engineered from known factors like lift, drag, center of gravity, etc. Then some poor schmuck of a test pilot takes the plane up and determines if the engineers got it right or if it needs a little tweaking (hopefully not a lot of tweaking)
