Hi guys.
I already have a machine on which I am using Leadshine ES M22430 motors with 3nm torque and ES D808 Drives. The machine is a CNC gantry and I use 20mm ballscrews with 5mm thread pitch.
The whole bridge weight is ~80kg and is driven by 2 motors (X Axis).
The Y axis motor is driving ~30kg
And the Z axis motor is driving ~15kg
The performance I get from the machine is ~6500 movement speed.

I am designing the new machine because I need longer X axis travel. Current one has 1000x450x180 and the new one I design will be 1600x450x200.
Also I plan to use again 20mm ballscrews but with 10mm thread pitch. I want to achieve bigger movement speed. My aim is 12.000-15.000.
The weight of the new bridge will almost the same as the current one, just a little bit heavier. I calculate it to be
85kg for the whole bridge
33kg for the Y axis motor to drive
15kg for the Z axis motor to drive

My current thought is to use the Leadshine ES M23480 motors with the same drives which have 8nm torque. 2motors for X and 1 for Y axis. And the ES M23440 motor for Z axis which has 4nm torque. The Z axis will probably be limited to lower movement speed since it will have only 200mm of travel.
Anyone that can help me decide on the motors?
Do you think they will be ok for the performance I want to achieve?

Here are the torque diagrams from the Leadshine website for the motors I use now and the motors I want to use on the new build.
