Linear Actuactors

Dear Friends....

I really like actuators and I'm planning my motion simulator...

I'm thinking about 3 actuators, 2 on my side, like in the line of my steering wheel one at back.

Like this video:

What about Stroke ? Is it 200mm so much? with a speed of 400mm/s or something like this.

I like this type of Actuators: http://www.xsimulator.net/community/threads/diy-actuators-plans-by-ian-bff-shortened-by-me.5279/

So, my questions:

About Engine Strengh, what nema with what torque I should use?
About Stroke, Is it so much?
About speed, Is it so slow?

Found some differente and cool linear actuators:

And this one: (Pneumatic)

Get some information for the motor and stroke....

The new motor is 24V 18.3 amps. The new pololu board works fine in tests so far. Don't know if I will do another round of load tests - as these motors are actually higher rated - but smaller in size - although lower in speed at 3300 rpm - so I'm more interested in how they track.

With 360MM Stroke.

Think 360MM is so much for me, about 200mm is so good.
Already saw that post but never read all it, now i got!

Thank you @noorbeast !

Hello @speedy !

I already take a lot there... Have some nice stuff... But thank you anyway

I don't mean to hijack this thread, but this question is relevant to the topic at hand:

Please note that price is outside the scope of these questions:

1. What type of linear actuators will have the quickest speeds?
- SCN5 seem to be faster than SCN6, but I don't know how they would compare to a high torque low ratio Worm Gear.

2. What type of linear actuators will be able to provide the most consistent accelerations?
- I looked at the SCN5 specs and it seems the speeds vary greatly depending on shaft length.

3. Could two linear actuators be connected in parallel with one another to increase the payload capacity?
[]======[]
[]======[]
In the design above the '[]' above one another would be a single mounting plate that would have two parallel linear actuators connected next to each other. The mounting plates would then be connected to the ball joints for uniform movement/rotation.
I would assume that if they are parallel they could share the same control signals.

Dear friend, this only helps! More questions, more things to avaluate!

No chance for me to buy actuator, but there is some way to build it... I have good knownleadge in mechanical... SCN5 are for few weight... use 2 are impossible, no way to buy 3, imagine 6...

For you to understand why i say impossible... $585.00 Each actuator with 200mm stroke... Here Dollar is 3.40 (+/-)

$585 = R$2000 each actuator... Minimun salary here is R$800.... ( This without tax, with tax total value X2)

I can buy a lot of things with R$2000, o think i can do 3 actuator with drives for this price... For heavy load, like 70KG...

Please ask more, this way I understand other ways for thinking and all beneficts or bad things....

Motors heres are few, every worm gear motor (US$100 +/-) so, R$350 with tax = R$700... Can be a good ideia, but still need MM...

Any advices ?

SO EXPENSIVE THINGS HERE!!!!!

OK ... How about AC motors ?
Take a look at my 3 phase AC motors simulator ...
History to me now but enjoy the videos .
