TWO PHASE SYSTEM KIYA HOTA HAY?

Two phase system jisay aksar two phase motor system bhi kaha jata hay. Ye aksar electrical motor mein istimal hota hay, Jesay kay two phase servo motor. Servo motor mein do windings hotein hein starting winding aur running winding. In dono Winding ko alag alag phase chahiye hota hay aur 90 degree ka difference bhi hota hay.

THREE PHASE CONNECTIONS ME STAR DELTA KYU USE KARTY HEIN.

Three phase system me ham motor connections me Star Delta use karte hein, Induction motor me ye use kyu karte hein? Ye bhhht interesting question ha. So me yaha kuch points btata hun jo is chees ka sabab ha.

1. Motor 3 se 4 guna starting current kam kar leti ha apny current se, aur current ky kam honay se Voltage automatically kam ho jaega, To losses bhi kam hoga.
   
2. Star Delta Controlling circuit, Voltage reduce hoga to Current b reduce hoga to induction motor ky jalny ky imkaan bhi kam hongay.
   
3. Aur addition mein, Motor ki Starting torque ziada hoti ha to motor ki winding kam chance hota ha jalny ya damage honay me.
