Which outcome occurs when a synchronous reluctance motor driven beyond its stable torque range in a closed-loop vector control circuit?

💡 Explanation

Resonant oscillation and instability occurs because exceeding the torque limit in field-oriented control triggers a **negative damping** effect within the drive loop. Therefore, oscillations increase, rather than the expected stability, due to current limitations hindering perfect torque control.
