Brushless Inrunner for Wind Tunnel Model

Hi could anybody give me some pointers on sourcing a couple of brushless inrunner motors for a wind tunnel model. I need motors capable of 60000RPM and able to handle around 2-3KW.

Neu Motors, neumotors , do what I'm after in spades i.e. their 1518 motor is just what I'm after, but they are not responding to my emails, does anybody know of a UK supplier ?

Hackers motor just about do what I'm after with their, E-50S 2.5D kv1800, but its a little under powered.
On their website  they state "I(0)@37V: 4,9A"  what is meant by the I(0)@37V. Is it fair to say if we provide a voltage of 37V its maximum current it can draw is 49amps hence  =1813Watts.

Any other motors out their in this class? I've done numerous searches but I'm not turning up much.

thanks

Nick

In Hacker speak the "I(0)" means no load current, so that statement means the motor will draw 4.9 amps if run on 37v with no load. That data can be used in "motor calculators" to help predict performance.

Have you looked at other european manufacturers?

They are all good quality items, and the Leomotion actually uses some Neu parts.

I doubt you will find many UK suppliers, but they are easily bought from european suppliers.

Dick, that's brilliant thanks, just what I needed. Lehner even have a calculator that I can input the RPM, voltage and current and it recommends a motor.

thanks
