Figure 1 : Asynchronous machine Diagram The Stator is a an asynchronous machine and indicated to that of the synchronous machine : 3 coupled enrollments as a star configuration or in triangular , they are powered by a system of equilibrium supply. it will result (FERRARIS theorem ) Of the creation of a sliding magnetic field in the gap of the machine . the sliding speed of the field compared to the stator is Ω s = ωs / p Where ωs indicates the pulsation of the tri-phased statoric power supply network , p is the number of coils in each coil , p therefor indicates the number of pair of poles ( one pair is constituted of the North pole and the South pole) Remark : The stator that is put on a variable field must be papered to limit the losses by Foucault currents. The Rotor of the machine sports a coiling similar to the stator : tri-phased coiling of the same number of poles as the stator . those 3 coils are coupled in a star configuration and a short-ci
