Electromagnetic Positioning Focusing Mechanism Magnet Orientation in a Digcam

I did a google search for "teardown Sony DSC-H1" (you might try tear down or tear-down).

Google instant came up with a lot more stuff for the H2 (which may contain the same part). But for the H1 this might be some use:-

Thank you for the link. I like the eserviceinfo they are a great resource. The link is for the level 2 service manual which only lists the lens block and gives no detail as to the components inside. Let me ask this question: in a voice coil motor, would each magnet be facing the coil be of the same pole? Like the N side of each face the coil?

You have helped me a great deal. It may have had 2 more magnets on the other side. So I am looking to create magnetic attraction with the red stripe magnets? Is that how the electromagnetic coil reacts to the field? Would it work with the magnets repelling instead of attracting?

I think that the simple answer here is no. The trick is to get the current (i.e. the wires) running at right angles to the lines of magnetic field. The magnetic field lines run from one pole to the other.

So I need to get each set of magnets attracting each other. Given the distance between the magnets, do you think there would be an alignment between the two blocks? Or is it as simple as getting both magnets on each side to attract then re assembling? What I am trying to say is that do you think that I should align each set of two magnets for a total of 4 aligned magnets? I truly appreciate your help.

Randall, I took the lens assembly further apart and discovered that the magnets on the opposing side also had red marks on them. At that point is was just a matter of aligning the marks and re assembling the unit. It works fine now. I thank you for your help and will mention you and CR4 by name on the instructable I will publish on how to repair a Sony Lens system. Thanks again!

I am 80% closer to getting this together. If we consider lines of flux, even if both L and R assemblies are properly aligned, and in proper relation to each other, all in attraction, then there are still 2 more combinations, and I am not positive if it would have any kind of effect on it at all. The mechanism itself moves laterally and not up and down, I suppose searching for a perfect position. If so and I get it wrong, then it is possible the sensors function moving one way or another until the focus is right. If so, then the orientation really is not that important.

Randall, here are the pictures that I could manage to upload. I ended up cleaning the inside lens of the outer lens assembly with scratch free microfiber cloth, and it scratched the lens pretty bad, but the camera works fine. Some pics were shot before I "cleaned" the inside lens and scratched it, others were shot after. Overall I am happy with how it turned out.

Wow, great pictures of awesome scenery. You have been well rewarded for persevering when many others would have given up. I can't tell which shots were taken with the dust and which with the scratches, but I guess that the originals are much bigger than my screen.

I hope you had a good Xmas, and are looking forward to some long walks in the high desert in the new year.
