high speed Asynchronous motor (22000RPM) needed

[Andrewboff]

Good day!
I'm looking for opportunity to make a custom Asynchronous motor with our parameters to test it.

We are satisfied with these motor parameters:
Asynchronous motor
Motor rated Voltage: 220VAC
Rated power: 4.2-4.5KW
Max Power: 4.5KW
Rated speed: 20000rpm-22000rpm
Max speed: 22000rpm
Insolation grade: H
Duty type: S1
Installation: B35
Cooling: Air cooling

The diameter of the shaft should be about 35-40mm.
At the moment we will need 2 identical motors.

Hi andto the forum.

Unfortunately, I don't think Golden Motor (or anyone on this forum) are likely to be able to supply a motor that fits your requirements as none of GM's existing motor range come anywhere near close to matching your specific requirements.

Golden Motor specialise in permanent magnet brushed and brushless DC motors aimed at DIY conversions of pushbikes, motorbikes, boats and cars etc.

They do not have any motors capable of operation on 220VAC or motors capable of spinning at speeds of up to 22,000 rpm. 

I would be extremely surprised if you managed to find anyone prepared to design and manufacture just 2 motors to your precise specification.
