Which part of a motor consists of three single-phase windings spaced 120 degrees apart?

The correct answer is the stator, which is a crucial component of an AC motor. The stator typically contains multiple windings that create a rotating magnetic field, allowing the motor to operate effectively. In the case of a three-phase motor, there are three single-phase windings that are indeed spaced 120 degrees apart. This configuration is essential for generating a uniform rotating magnetic field, which interacts with the rotor to produce motion.

Each winding corresponds to a phase of the power supply, and when AC voltage is applied to these windings, they generate magnetic fields that are also spaced equally apart in time and space. This design is pivotal in achieving smooth and efficient performance in three-phase motors.

The rotor is the rotating part of an electric motor, which is influenced by the magnetic field produced by the stator. The commutator, typically found in DC motors, serves the role of reversing the current direction in the rotor windings to maintain rotation. The armature refers to the component that generates the electromotive force (EMF) in motors or generators, often located within the rotor or stator, depending on the design. Understanding the roles of these components helps clarify why the stator is the correct answer, as it directly relates to the specific
