Linear actuator

Exactly what I calculated too. As others have pointed out, the 'real' mass for which this will be acheivable assuming some ramping of the acceleration, will be less... Given that a motor system will itself have inertia, and inductance, and switches or valves will take time, and the short times involved, the extras will be quite large.

Electric means a motor with a gearbox to handle 1500W aka

2 horsepower. A synchroneous motor with sliders or a brushless will do. The gearbox needs proper dimensioning.

For those not knowing, the first gear in a car is dimensioned to last 30 miles or so. Then the teeth are falling off...

Together with a 2HP frequency inverter to generate the appropriate signals you'll be throwing out a stack of dollars. Compare that with a pneumatic system where together with the actuator, a compressor is required, or with a hydrolic system where together with the actuator, an oilpump is required.

Say about 225lbf.

Could be, but the application does not require every stroke to be max length, or pulse at 5Hz. I would guess in practice about 10% of max.

Go to your nearest pinball machine distributor, and see what a flipper solenoid can do for you.

Good Luck! Rich

1 newton is the gravitational force between the Earth and an average-size apple. A bit over 3.5 ounces.(;-)

So, at 1000 Newtons, 250 pounds of static force, much less dynamic when velocity profiles are considered.

Such an app is Waaaaay into pneumatics or hydraulics.

Linear actuators would be inappropriate and outrageously expensive for all but the most precise of applications at these force levels and speeds.

Commercial driver electronics alone are often several thousand dollars each.

That is why use of linear actuators is so utterly miniscule compared to P&H.

But, I'll be happy to sell you one (only seven left, actually) anyway.
