A brushless DC motor requires a commutator to operate.

Explanation:
A brushless DC motor does not require a mechanical commutator. In brushed motors, a physical commutator and brushes swap current in the windings as the rotor turns. In a brushless DC motor, the rotor has permanent magnets and the stator windings are electronically switched by a controller. The controller uses position feedback (from Hall sensors or back-EMF sensing) to energize the correct windings at the right times, creating continuous torque without any moving commutator contacts. So the statement is false because the motor relies on electronic commutation rather than a physical commutator.
