Which component in an electric motor is responsible for generating magnetic fields?

The component in an electric motor that generates magnetic fields is the stator. The stator consists of windings or permanent magnets situated in the stationary part of the motor. When electricity flows through the coils on the stator, it creates a magnetic field. This magnetic field interacts with the rotor, which is located inside the stator, and is responsible for the motor's rotation.

This process is fundamental to the operation of electric motors. While the rotor also contributes to creating a magnetic field when it is energized, it is the stator that primarily serves this function. In contrast, the armature typically refers to the rotating part, which usually consists of coils that also generate a magnetic field. The commutator works to switch the direction of current in the rotor coil, but it is not a source of magnetic fields in itself. Thus, the stator is the key component for generating the magnetic fields necessary for motor operation.
