Galileo Ferraris
Galileo Ferraris (Livorno Ferraris, October 30th, 1847 - Turin, February 7th, 1897) is a Engineer and a Italian Scientifique. He worked on the magnetic fields S turnings in the electric machines supplied with Alternative course
The theorem of Ferraris shows that a spinning field pattern can be created by three Bobine S positioned in Arc of circle with a shift of 120°, each one supplied with a Phase of an electric current Triphasé. The rotational frequency is then equal to the frequency of currents of food. It also shows that 3 p reels fed in three-phase current and shifted 120°/ p make it possible to obtain a spinning field pattern with a rotational frequency F / p , F being the frequency of the currents of food.
