Which part of a three-phase motor remains stationary?

In a three-phase motor, the part that remains stationary is the stator. The stator is the stationary component that houses the windings or coils and generates a rotating magnetic field when alternating current flows through it. This rotating magnetic field interacts with the rotor, which is the moving part of the motor, causing it to rotate and produce mechanical power.

The stator plays a crucial role in the operation of the motor, as its design and winding configuration dictate the characteristics of the magnetic field produced. As the current changes direction in the three-phase system, the stator's changing magnetic field induces current in the rotor, leading to its movement.

The rotor, in contrast, is the rotating part of the motor and is designed to turn within the magnetic field created by the stator. The commutator, typically found in DC motors, is not present in most three-phase motors and functions to switch the direction of current flow in the rotor windings. Conductors are the materials through which electrical current flows and can be found in both stator and rotor components, but they do not refer specifically to the stationary or moving parts of the motor.
