Very fast linear actuator
Very fast linear actuator
(OP)
I am working on a project that requires moving a 100mm long and <.5mm diameter pin a specific distance in a straight line. I want to move the pin in and out as fast as possible and accurate to less than .05 mm. The device needs to be as small as possible. The stepper linear actuators on the market appeared to be a good option but they look too slow and expensive. I was looking into using the electromagnet from a speaker, but I am not sure how to calculate the speed and accuracy of the push/pull. Any advice would be helpful. Thanks.

How far is a "specific distance"?
How fast is "as fast as possible"?
How much better than .05 mm positional accuracy do you need? Do you need it on both ends of the stroke?
How small is "as small as possible"?
How do you expect to make a decision or get any advice if you can't clearly express what you need?

How can something that is 50 mm in size achieve a 75 mm stroke?

But in general, shmoey212, you can't store five feet of arm length in a space less than five feet.

Yep. Which is why I didn't state that is was impossible.

Servo controlled or open loop controlled with encoders for position.
