Power Needed to Rotate a Mass to a Speed in a Specified Time 6

[edison123]

What will be the power needed to rotate a uniform cylindrical rotor
weighing 1600 kgs
dia 600 mm
speed 3300 RPM
5 minutes acceleration time from zero speed to 3300 RPM

Any particular equation to calculate this? Will acceleration time play a role in power needed?

The cylindrical rotor will be rotating horizontally in free air on two bearings.

Update:

We ran the rotor today at 3300 RPM with VFD input of 36 KW with manual control of speed in 5 minutes. Tracks closely with the calculated 28 KW if you account for the VFD losses and two centrifugal fans loss.

I thank you all once again for your valued tips. First time, we did a high speed balancing in our workshop with our in-house designed balancing system.
