Concept:
BLDC means Brushless DC motor. It has electronic commutation instead of mechanical commutation.
Step 1: In a BLDC motor, permanent magnets are usually placed on the rotor.
Step 2: The armature windings are placed on the stator.
Step 3: Since windings are on the stationary part, there is no need for brushes and commutator.
Therefore:
\[
\boxed{\text{Stator}}
\]
