Active Magnetic Bearing: Tripod Floater v2.0

[meindertnorg]

Hi grick31,

I'm using a digital servo, implemented in a Texas Instruments C2000 micro-controller. The servo-sampling frequency is 10 kHz.

also check out the 'Tripod Floater v2.2' for a battery operated version.

regards,

Meindert

Very nice!

At what frequency does the controller "check" the distance between the plate and magnet, or is it a continuous feedback loop?

Thanks

very nice! Just getting into microprocessors and was thinking about magnetic levitation

Very nice work sir.

That's pretty cool :)

Very impressive

What's the freq of the electro-magnets

[meindertnorg]

@polarkerr

The electro magnets are not operated at an AC frequency, but with a DC current that is adjusted by the 'gap' controller. e.g. if the gap is too large, the controller will ask for a larger current, and if the gap is too small (magnets are too close to the plate), the current is decreased.

Nice work Meindert!

Wonderful project Meindert !

Interesting DSP board as well. Did you use the TI compilers or something else ?

Lucas, I used the standard TI Code Composer Studio for this project.
