Have my prayers been answered?
Does anyone know anything about this motor?
--------------
K9" 220V boldly goes where no motor has gone before. It features over 6500rpm as nominal and close to 32kW in a 9"/45kg package. It is actually the first unit to benefit from our new high speed commutator for 9" motors. Appart from that it has a switchable stator field and covers 96-220V all at optimised rpm. K9" 220V is designed to take advantage of the upcoming Soliton JR controller.

Seems like a new offering from kostov-motors, I would email them about it and ask all your questions...They are very good about communicating and working with customers about their needs and wants...

With the Soliton-1 controller 220KW(295HP) is possible for as long as the motor can hold 1000A at speed, however with 220V i imagine the 295HP would only be available up to 3500rpm or so...

I have an old Kostov, I like it. I really like that fan setup on the new one! The high rpm tricks are neat, too, more like something you'd expect at NEDRA than a forklift motor shop.

How do you arrive at 300 HP peak number?

RoughRider may have been referencing my post above stating "295hp"

220V*1000A = 220kw = 295hp ~ 300hp

"With the Soliton-1 controller 220KW(295HP) is possible for as long as the motor can hold 1000A at speed,"

@ Bowser ... yes, right...

I received the following reply from Tesseract when I asked about the Kostov 9" back on Dec 29, 2010

That said, we haven't yet received any of the new 9"/220V Kostov motors, but we do have some of the new 10" and 11" models. Kostov has been working with us for the last year to better tweak their motors for EV applications, and, in particular, with our controllers. The new 9" motor should be a perfect match for our Soliton Jr. controller, but I have not actually tested one yet.

Thats great, a stronger higher voltage kostov 11" combined with a soliton-1, maybe 270V sagged? * 1000A = 270kw = 362hp (from 0-5000rpm)

Hey Plamenator,
Are there performance curves for this motor yet. [Don't see them on the website.]
