STEvil Posted May 11, 2010 Author Report Share Posted May 11, 2010 (edited) how about an electromagnetic motor (in place of the standard magnet structure) coupled with a voice coil? I asked Dan Wiggins that one once iirc and tossed a few emails back and forth but didnt get very far on it.

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.

I asked Dan Wiggins that one once iirc and tossed a few emails back and forth but didnt get very far on it. Quite... I have been thinking about this allot, but have never asked. I was thinking it would make it more impractical and cause issues with linearity, but I want to hear what the pros say Quote My RE MT 18" wall build Former build, farewell beloved wall.In progress, Toyota Starlet build This forum has a massive boner for ridiculous electrical upgrades.

sundownz Posted May 12, 2010 Report Share Posted May 12, 2010 Got any links? Read about it in a book from the library in college, so no, I don't... but they used to do it WAY back in the day when permanent magnets were expensive.

Woah, I would have thought wire would always cost more O_o .

STEvil Posted May 13, 2010 Author Report Share Posted May 13, 2010 That was done back in the 1920s... IIRC. Yeah, thats what Dan said. I dont think you would have problems with linearity really.. especially if you used a spider setup like linked in some of the above subs.

Dan is a great resource... learned ALOT from him years ago when he was active online.
