Adire Audio's new motor (Parthenon)

Re: Time to knock heads

Ok. If you can supply the machining, I can supply the FEA-optimized motor design. (Actually, I already have a couple designs, complete with unique suspension, but I can't share until my patent apps are submitted.)

OK Bill lets see what the two of us can come up with. I've built drivers from the motor up before. The suspension is one of the harder parts. Now what are your ideas???

Bill, Mark, and Mike...
I'd love to be involved in this, but being a new member (here), I'm being "moderated" or something... 🙄

I'm not sure if you've got it, Bill...
But I'm actually an official XBL^2 licensee, so I've got Adire's official FEA software for modeling up XBL^2 motor designs.
I'm sure you've got something similar... at a minimum, you certainly do know your XBL^2, as evidenced by your earlier deduction, pre-Adire-revelation. 😎

Not sure how else I can be involved, but I do have some industry relationships... heh... I'm not sure that would count for much here, as these are likely not going to be "off the shelf" parts here. 😀

Bill probably knows by our interactions on CarAudioTalk.com that I've got an extreme interest in custom, one-off audio projects...
I've got my own custom twin-motor rotary servo subwoofer project (that I've unfortunately had to shelf for several months)that can't hope to displace as much as this project...
Obviously, I'd like to help as much as I can.

...reaching a status of not being moderated would be an excellent first step, I think.

Yo Chris!

WOW Your rotary sub effort is, dare I say, brilliant! I'd never seen it before. I'm extremely impressed with your work. I hope you find time to finish it someday.

By the way, if any of the rest of you are interested, we're putting our heads together to figure out how to DIY something Parthenonesque here.

i was wondering do you know of any online sites that show diagrams and information about the magnetic circuits and flux densities etc in speaker magnets??

Hi Michael,

Sorry, but I'm not familiar with any such sites, especially having to do specifically with speakers. They probably do exist, I just haven't ever tried to Google them up. Whenever I wonder how flux will flow through a system, I model it up on my magnetic FEA software and have a look! 🙂

If you're game, search for FEMM. It's a free FEA package that's pretty easy to use.

Thanks for the compliments! 😎

I really do hope I can get the time to get back to it too.
My real setback was in that I used that stupid spray glue...
...ironic because you don't know how many times I've suggested people use the roll/brush on liquid contact adhesive over the spray glue... maybe it's just me.
At any rate, I used the spray glue, and my laminate panel is starting to delaminate.

I decided take my mind off that, while still moving forward really... to dissect my PG Cyclone to see what made IT tick, primarily to discover the mystery of its suspension, and how it compared to mine (it's interestingly a torsion rod... clever, I think). You seem like just the sort of person who might also find that page interesting! 😀

I dont' know if you read the intro on the servo project, but the Cyclone was aimed at the SQ crowd...
So I basically wanted to see if I could take it in the other direction, the pure-SPL driver approach, without regard for (primarily because I lack the facilities for it - because this ain't no standard loudspeaker ! 😀) the aspects that lend themselves to SQ.

It'll be fun when it's done, I hope!
