Problem with PMSM motor model in Simulink

In summary, the speaker has developed a Vector Control for a PMSM motor in Simulink using Simscape Electrical, but the motor is not spinning despite trying various speed values. The error signal tracks the input correctly, but the motor does not move. The speaker is asking for help to analyze their simulation and determine the issue.

TL;DR Summary
Field-oriented controlled PMSM motor won't spin. Motor speed oscillates initially for 1 second but oscillations die at 0 rad/s and have no idea of why this is happening in simulation
Good afternoon,

I have developed a Vector Control for a PMSM motor in Simulink using Simscape Electrical but my motor is not spinning. I have tried applying various speed values but nothing happens. I am applying a step signal from 0 to 300 but the motor speed still doesn't move. My error signal, however, tracks my input as it should. I do not know what has happened. Could someone look at my simulation and tell me what is going on ? My simulink can be downloaded from my OneDrive and the screenshots of my signals are attached.

Can you show graphs for both voltage and current waveforms at the motor?

Then it is a matter of signal tracing to see where it isn't doing what you think it is!
