Which phenomenon arises when a three-phase induction motor operates with a significant voltage imbalance between phases?

💡 Explanation

When voltage imbalance exists, a negative sequence current component is induced because the stator field rotates in the reverse direction, inducing increased rotor currents and consequently causing motor overheating. Therefore negative sequence current and overheating result, rather than resonance, increased efficiency, or speed increase which require balanced conditions.
