Rewind 3 phases motor for higher power rating?

[Vortex 22]

Hi,
Is it really possible to
Rewind 3 phases motor for higher power rating ?

Assuming that we have 3kw power motor

It's possible to rewind that motor for higher voltage input
Say  we need a 10 kw motor?

Sorry, I know this no free energy but it's related subject!!!

Many Thanks
Regards

No.
Because this involves thicker windings, then deeper grooves in stator, larger stator ect.
Re-winding of small size 3 phase motor may cost the same like a new motor and is practiced when motor windings did burn.

I don't know for sure
But is it possible to rewind the motor using thinner wire and more turns?

It is not simple like that.
Designing 3 phase motor involves many calculations because there are so many variables- number of poles, number of rows and the size,  rpm's, single or double windings, voltage ratings, motor rating for continous work, intermittent load, starting mode, VFD mode ect.
Generally rewinding is performed when it is economically sound, on bigger, expensive motors.
Smaller motors- it is better to buy a new one.
Month ago I was involved with modifying 3 phase squirrell cage motor with neodymium magnets and I gained some knowledge, spoken to people dealing with electrical motor repairs and rewinding.
Cost of rewinding 2,2kW motor exceeds price of a new one, at least in the city I live.
