3 Phase
Why there is 220v in 1-phase but 440v in 3-phase?

The output of generator having 120 degree phaseshift. Ever time the instantaneous magntiude will be root 3 times the phase voltage. The magnitude will be same. While measuring we are considering the two phases which is maximum.

The Phase voltage of an generator is 220 - 230 V but the Phase to phase voltage (Line Voltage) will be 400 V. Voltage of R - Phase-230 Y - Phase-230 B - Phase-230 but RY-400V BY-400V ...

Synchronous Machine
We know synchronous machine run at a constant speed.Consider Synchronous motors, If you load the machine, will the speed reduce? If it does so, then it prohibits the property of synchronism. So Explain What is happening?

In synchronous machine speed always remains constant even when load on it changes. For increased load motor develops increased torque because of rotor falling out of phase by large angle delta; which...

Even if you increase the load on synchronous motor upto specified limit, SPEED will NEVER fall down(unlike dc or induction motor), while maintains synchronous speed. BUT why??? It takes more current ...
