What is three phase winding?

they are winding wound in such a way that they deliver three times the power


What is the voltage output if the transformer is connected backwards?

It doesn't really matter which way around you use a transformer, the primary winding is ALWAYS whichever winding you connect to the supply, and the secondary winding is ALWAYS whichever winding you connect to the load. For either connection, the turns ratio will ALWAYS equal the voltage ratio for an ideal transformer (or close enough for a real transformer).


What are the uses of damper winding s in synchronous motor?

to achive constant speed and provide a eassy way to inter loacking with syn fluxDamper winding is a short circuited winding which are useful in preventing the hunting(momentary) speed fluctuation in alternator and are needed in synchronous motor to provide starting torque.


Why is the winding of the second phase reversed in the 3 phase synchronous motor?

That might be to make it run the right way.


What wll happen if the starting winding in a split pase motor fail to energize?

The motor would not start rotating. The motor will just hum and the rotor will be stationary. If you can get the rotor to start turning the motor will still run on its run winding.I have a cement mixer that has a motor with a burnt out start winding. All I have to do is turn the barrel and the motor will start turning over. Without the start winding you have a choice of which way the motor will turn. If I turn the mixer barrel the opposite direction, the barrel will turn that way until I turn the unit off.
