Motor for 75000 RPM
Motor for 75000 RPM
(OP)
Dear colleagues,
We have designed compressor for 75000 RPM and 1,5kW, but now have difficult time finding motor supplier.
Please, can you suggest high speed motor manufacturer.
Thank you in advance.

(Was this whole project not thought through before committing to the design?)

That said, I have run across a turbo blower mfr that claims they run their blower at 1250Hz, and in looking at their brochure, the photo of the VFD inside of the box looks to be a Vacon product.

I looked at Vacon's spec sheets and they don't list an output frequency higher than 320Hz, but it may be a special version that they build for this OEM. You might try to call them and see if they will share that info with you, but if you are going to be competing with them, don't count on it.

Are you sure its 75000 rpm and not 7500 rpm.If it's 7500 rpm you can use a VFD and double the frequency and size the motor within it field weakening range.

75K RPM will produce a prodigious amount of rotational inertia. I've worked at two places in my career in which a large process compressor and a large process vacuum pump both were spun at much less speed (range of 10,000 to 15,000 RPM), failed due to mechanical issues, and the workday became very...exciting.

we also routinely sold many 3000 hz output v/hz drives during the great USA machine tool market in the 70's thru about 2000 - mostly for high speed grinders. We seldom need over about about 1666hz anymore today, but Spindel (aka old Volkmann) still will sell you a very high performance 3000hz drive from 1-300hp today (spindel.com), from stock on most.
As you know, we can no longer supply over, IIRC, 400hz max output for sale outside the USA without ITAR government permission. Those less than friendly countries want them real bad for making nuclear bomb stuff.
So they do exist.
