I am looking for a high frequency VFD 400-700Hz. Everything I can easily find tops out a 400Hz but I need 660 for a 40k spindle. Any idea where to look? Thanks.

open loop?
sensorless vector?
v/hz style?
vector?
voltage? current?
we offer all of the above.
should the OP be looking at a 600v system so as to get better v:hz ratio and increased hp at higher frequency?

Since October 2010, various reports began to suggest that a sophisticated computer malware
(worm) attack may have targeted Iranian nuclear facilities for more than a year,
which could help explain why the number of operational centrifuges at Natanz began
to decrease after May 2009.70 In November 2010, Symantec published a detailed report
analyzing the malware (Stuxnet). The report confirms that the worm is most prevalent
in Iran (more than 60 % of infected hosts) and designed to sabotage industrial control
systems and, even though not explicitly considering enrichment plants, reveals that
frequency converters (operating between 800 and 1200 Hz, i.e., a typical frequency
range for gas centrifuges) are the main target of the attack.71 In late November, some
reports suggested that Iran had temporarily halted all enrichment activities.72

....But I could not find anyone to actually sell me one yet (at least easily in stock and shipping to Canada)......
Unfortunately the motor does not have the leads to up the voltage.
Hey Mike,
Yes the spindle rated 380 @400hz 12,000rpm, but my client requested for Max speed 22,000rpm, looking for 800Hz inverter.
