- 1The motor's power factor will improve (become closer to unity).
- 2The motor will draw less armature current to compensate for the increased load.
- 3The motor will initially slow down slightly, causing the torque angle to increase.✓
- 4The motor speed will decrease proportionally to the load increase.
Correct answer
The motor will initially slow down slightly, causing the torque angle to increase.
