In a 3-phase synchronous motor, if we increase the torque applied to the shaft, what happens to the torque angle 8? increases in the positive (leading) direction O cannot be determined with the given information increases in the negative (agging) direction O tracks the rotor field at zero degrees A synchronous motor has a mechanical load applied to it, so that the rotor field lags the stator field by a mechanical angle of 30° (ie, the torque angle is 30%). This means the motor's power factor is O 15% O 87% 09% cannot be determined. The power factor depends on the Seld cument and Seld voltage drop For a 3-phase synchronous motor, we can change it's power factor by adjusting O the line frequency the field current the stator current the stator voltage

Question
In a 3-phase synchronous motor, if we increase the torque applied to the shaft, what happens to the torque angle 5? O it increases in the positive (leading) direction cannot be determined with the given information it increases in the negative (agging) direction it tracks the rotor field at zero degrees A synchronous motor has a mechanical load applied to it, so that the rotor field lags the stator field by a mechanical angle of 30° (.e., the torque angle is 30%). This means the motor's power factor is O 15% O 87% 0 95% cannot be determined. The power factor depends on the field current and field voltage drop For a 3-phase synchronous motor, we can change it's power factor by adjusting O the line frequency the field current the stator current O the stator voltage please answer all subpart in typing format
