🔍 Key Concepts

• Three-phase induction motor behavior when one line opens (single-phasing) • Effects of light load vs. heavy load during single-phasing • Changes in torque, vibration, and heating when a motor loses one phase

💭 Think About

• Think about what happens to the rotating magnetic field in a three-phase motor if one of the three supply lines is lost—does the field stay smooth or become unbalanced? • Under a light load, can the motor coast and keep turning even with a problem in the supply, or must it stop immediately? • How would unbalanced current in the remaining two phases affect torque, temperature, and mechanical smoothness of operation?

✅ Before You Answer

• Confirm what single-phasing means in a three-phase motor and whether the motor can still turn if already running under light load • Consider whether torque increases or decreases when one phase is lost, and how that would affect the ability to drive a load • Check whether unbalanced operation would more likely cause cooler operation or overheating and vibration
