brushless motor

[aLeSsAnD.Ro]

hello to all, I am a mechanical engineering student (triennial) and so' little electric motors, less than brushless engines. I have a doubt: we have an engine that delivers 10kw, with a nominal torque of 50nm and a nominal spin of 1909,85 rpm. in case my application required a power of 5kw and a pair of 10 nm, the number of turns what would it be?
My main doubt is: Does the engine always provide 10 kw or can it be adjusted to provide less power?
excuse ignorance

can be adjusted, those indicated in the catalog are the maximum performance.

Thank you! !
So let's say that my engine has 10kw and want to use it at a fixed number of laps and with various torque values, could I use it for example at 50 nm and 1000rpm fixed or could I use it at 1909,85 rpm with 45 nm confirms?
