Use WLTC drive cycle data instead of step input

I’m currently working with the PMSM thermal model. I replaced the input speed (RPM) with custom WLTC speed data, specifically the first 50 points of the WLTC profile. I adjusted the simulation time to 50 seconds accordingly. I also interpolated my data to have a time interval of 0.01 seconds, and I verified the input RPM values using a plot—everything appears normal.

However, I encountered the following issues:

1. Torque Not Measured: In the simulation results , the demanded and achieved torques are not being measured.
2. Temperature Explosion: After around 10 seconds into the simulation, the motor temperature exhibits an unexpected and unrealistic spike or explosion.

I’ve carefully checked the input RPM data, and everything seems fine. What could be causing these issues? How can I resolve the torque measurement issue and fix the temperature explosion problem?

Any help or suggestions would be greatly appreciated!
