Which outcome occurs when a large industrial three-phase induction motor operates under sustained undervoltage conditions?

💡 Explanation

When a three-phase induction motor experiences undervoltage, increased current occurs to deliver the required power because power equals voltage times current, leading to increased stator winding resistance heating and reduced efficiency, which causes overheating and increased motor slip. Therefore, overheating & more slip result, rather than instability, distortion, or saturation which require more complex system interaction.
