What exactly is nominal stroke on a linear actuator?? And can I find a 1 inch nominal linear actuator online? Or do we have to build one ourselves??
Thanks, Taggerun |

Re: Nominal Stroke???
"Nominal" means "we designed it to actuate x inches every time, but your conditions/use may vary, so we can't guarantee it will actuate x.0000000 inches every time."

Re: Nominal Stroke???
Basically, they say it's a, for example 1" stroke, but they can't guarantee it'll be exactly that for every use and condition.

Re: Nominal Stroke???
If the manufacturer calls it a 1" stroke, and you buy one and measure the movement to be 1.05", then it's still legal, because the nominal spec is 1" (manufacturer spec).

Re: Nominal Stroke???
Remember it still has to be powered by a legal FRC motor. Amazon is full of options, but AndyMark is the only one I know of that sells COTS legal linear actuators for FRC.

Re: Nominal Stroke???
If it's powered by a motor, then it is just a gearbox and it can have any stroke. (e.g. DART linear actuators). This rule is referring to non-DC brushless linear actuators like solenoids and the like. They can only have a 1" nom. stroke max.
