What is the stated purpose of the stator in AC motors?

Explanation:
The stator’s job is to create a rotating magnetic field. When the stator windings are fed with alternating current—often three-phase—the currents are time-shifted so the magnetic flux sweeps around the stator. This rotating field interacts with the rotor, inducing currents in the rotor conductors and producing torque that makes the rotor turn. The stator doesn’t power the rotor directly, nor does it store energy or primarily serve cooling; its essential function is to establish the rotating magnetic field that drives motion.
