why transformer has more efficiency compare to rotating
machine?
Answer Posted / ramesh behera
The transformer which is working by mutual induction process
for which the magnetic lines of forces are linked with other
in terms of voltage and current
1- there is no relative air gap motion between two winding
such as bearing or bushes
2-the primary which act as stator but no rotating torque for
rotor only flux transmission
so as no energy loss which last for more efficiency
