High speed motor
(OP)
I am having difficulty sourcing a high speed electric motor.
30,000 to 40,000 rpm, +1kW
Wish to do tests on spinning object.
Know of any suppliers out there?
Any help welcome.
thanks

RE: High speed motor
as suggested before, maybe you will be able to find a spindle motor which runs at these speeds, though I think it will be very difficult because machining something at 40000 rpm is typical only of those milling machines for "micro-finishing" (use Ø0.4 mm tool or so), and due to the precision of this kind of machinery, the manufacturers are very jealous of their techniques, so they produce for themselves and nobody else.
IMO, you could investigate the use of a lower speed motor (10000 - 15000 rpm) coupled to a multiplier (provided that you have enough torque though...)

Above ~25,000 rpm, you're typically looking at very fancy and expensive motors with specialized controls, or more ordinary motors with flat belt speed increasers.

You are contemplating working in a speed range where safety is of paramount importance. I've witnessed a rotor comming apart at 50,000 rpm and it wasn't pretty.

Here is the company that supplied some high speed motors for us. They also carry the router motors mentioned by MintJulip

You would possibly have to modify the shaft to take your particular drive system, and at these speeds, that needs to be well balanced, even on such a small diameter.

Maxon manufactures very high speed and very high quality motors, but the price is elevated too.

I'd look toward building a support spindle with desired nose or face configuration and belt drive it 2 or 3 to 1 via a lower speed motor using a poly V tybe belt.
This is a "spin test" device wheterh intentionally or indvertently. Proper containment via a stout lead lined drum or buried vessels would be prudent
