SINAMICs drive for rapidly ramping & extremely power-dense Emrax 228 motor?

I have a customer who wants to use an S7-1200 to control this motor, and is asking for a Siemens drive. It's a brushless synchronous three-phase AC motor. He needs to ramp it from zero to 2500rpm in ~0.4seconds, then slowly ramp it back to zero. It will consume 32kW peak possibly up to 50kW. It's normally used in electric planes/cars/boats  but this is a stationary application.

Any suggestions?

Thanks in advance!

Looks like a toque motor to me.  Use an S120 variant and servo control.  You will also need an encoder.

It order to properly size the drive, you will need to know the connected load inertias.  You will need to see what the power module Imax is, but it should be minimally 150%, so base your acceleration torque on that.
