O A. rotor bars.
B. bearings.
C. controller or starter.
OD. stator windings.

Answer 1

The most common failure item with a three-phase induction motor system is the stator windings.

Step-by-step explanation:

The most common failure item with a three-phase induction motor system is the stator windings. The stator windings are subjected to high electrical and thermal stress, which can lead to insulation breakdown and short circuits. This is often caused by excessive heat, overloading, or voltage imbalances.
