Hi - I'm looking for a VFD that will cope with 3333hz - It's to run a 200k rpm .5kw spindle.

Any ideas on suitable models?

I would contact the spindle manufacturer for a recommendation. That sounds like a really special VFD.

And i thought our 60K spindles were fast. Holy smokes!

Its basically a pcb drilling head, I was wondering about modifying a normal (cheap) VFD as it's only 500 Watts.

It'll be great for my engraving.. Lol

Manufacturer has closed shop so no details about it unfortunately.

I'll probably end up making an inverter VFD to run it.

Maybe these guys can help V&T EcoDriveCN® variable speed drive (VSD): output frequency: 0 - 3000 Hz

just thinking anyone know any VFD that can go 800hz? i need it for my atc spindle

There are lots that are standard 1000Hz that will suit your 800Hz spindle all from the regular sources Ebay Amazon Etc

there alot chinese brand but i prefer reputable brand just now im thinking about delta

Yes Delta is a good VFD Drive but it most likely you will find that it is made in China, most are even the top manufacturers so just with every good brand name, there are copies out there also so beware

You may find it a little difficult to find high frequency output VFDs. By US export law, most VFDs and motor drives are limited to 590Hz output frequency in order to prevent the proliferation of nuclear centrifuges. Most manufacturers follow this limit, while others can apply for exceptions. I do not know how non-US laws control this.

Btw, I've NEVER heard of a 3333Hz motor. That's insane.

The VFD with these specifications might need to be special designed and made.

yes thanks for insight i just pull the trigger for delta ms300 5.5kw 1500hz output with built in emc filter

[machinehop5]

1000hz is Law in USA (I think) or was it Ohm's Law apply's...maybe Newton's Law...spin .. repeat..spin

[mactec54]

yes thanks for insight i just pull the trigger for delta ms300 5.5kw 1500hz output with built in emc filter

The built in EMC filter does not eliminate the Input Power Filter Required

thanks for reminder and knowledge i should get 20a 3 phase emi for it

No this depends on the amperage required for your VFD Drive check the max output amps of the VFD Drive and double it that will be your Filter and Breaker requirement

i just check my motor only need 4.5kw 9.1a 380v ..my drive max output is 22.5a factory setting should i get 50a emi filter?

Your spindle motor has to be 220v/240v you can not run it if it is 380v when you only have 240v supply check this spec first should be around 14A to 15A for the spindle at 220v so 30A should be fine, the VFD Drive is larger capacity which is good
so then we can go of the Spindle max current draw

im from malaysia i buy 3 phase 5.5kw drive in here we are using 230v for 1 phase and 415v for 3 phase owh here is my motor spec
