What does the motor stator contain?

The motor stator contains the windings and housing, which are essential components of the stator assembly in an electric motor. The windings are coils of wire that create magnetic fields when electrical current flows through them. These windings interact with the rotor's magnetic field to generate motion, which is the fundamental principle behind motor operation.

The housing, often made of metal or high-strength plastic, serves to encase and protect the winding insulation and contributes to the motor's structural integrity. It also helps in dissipating heat generated during operation, ensuring that the motor remains functional and efficient.

In contrast, other choices include components not found within the stator: the rotor is a separate part that rotates within the magnetic field generated by the stator; batteries store electrical energy and are not part of a stationary stator assembly; and a commutator is associated with certain types of electric motors (like DC motors) but is not a part of the stator. Recognizing these distinctions clarifies why the correct answer specifically focuses on the windings and housing as the defining elements of the motor stator.
