PMSM specifications determination Simulink

Hi, I'm currently using the PMSM in Matlab Simulink in combination with the Vector Control. I've tested the PMSM and the highest possible torque it can produce seems to be 1400 Nm at about 950 RPM. If I use the speed input of the PMSM and attach it to a ramp, I get a torque-rpm curve that looks about right, but still the maximum torque is way higher than what I'd expect. This is the curve I get:

(yellow = torque, purple = rpm)

Is it possible to calculate the motor's maximum power from this? And is there maybe a way to create a PMSM model with personal specifications?

Thanks in advance.
