Rotating Magnetic Field in Three-Phase Induction Motor
Rotating Magnetic Field in Three Phase Induction Motor - When 3-phase supply is fed to the stator winding of the 3-phase induction motor, a rotating magnetic field (RMF) is produced. This magnetic field is such that its poles do not remain in a fixed position on the stator but go on shifting their positions around the stator. For this reason, …

Exploring Three-Phase Motors: Types and Operating …
The magnetic field of the rotor interacts with the rotating magnetic field of the stator, causing the rotor to turn. By varying the three-phase rheostat, the strength of the rotor's magnetic field can be varied. If the magnetic field is lessened, the rotor speed decreases. When the magnetic field is strengthened, the rotor speed increases.
