## Giant Rotor & Stator Production Process For The €500 Million Hydroelectric Plant. Rewinding Motor

The stator is the stationary part of the machine, whereas the rotor is the movable part of the machine. The stator core, stator winding and the outer frame are the three parts of the stator whereas the rotor core and field winding are the parts of the rotor. The three-phase supply is given to the winding of the stator.

In an electric motor, the stator provides a magnetic field that drives the rotating armature; in a generator, the stator converts the rotating magnetic field to electric current. In fluid powered devices, the stator guides the flow of fluid to or from the rotating part of the system.

Maxwell’s equations, or Maxwell–Heaviside equations, are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, and electric circuits. Wikipedia

The four Maxwell equations, corresponding to the four statements above, are: (1) div D = ρ, (2) div B = 0, (3) curl E = -dB/dt, and (4) curl H = dD/dt + J.

Examples of Maxwell’s equations can even be found in homes. Induction stoves use magnets to create heat. Microwaves use two magnets that produce a magnetic field that causes microwaves to be sent out and vibrate the molecules in the food, producing heat. Televisions use electromagnets to direct energy flow.
