Why are transformer more efficient that rotating electric machines?

Because the electrical parts of a transformer do not move / rotate.

∙ 9y agoProbably the main reason is that transformer have no moving parts and, therefore, don't have to overcome friction and windage (air resistance).

Which loss is not common between a transformer and rotating machines?
Frictional , rotating losses are not common to transformers and rotating machines. these are specific to rotating machines.
Why are transformer more efficient than a rotating electric machine?
Transformers inherently do not have frictional losses, but transformers and rotating machines perform completely different functions, so I'm not sure it is fair to compare them. Transformers are used to transform electric energy (the input is electric energy, and the output is electric energy). Rotating machines either take electric energy and convert it to mechanical/kinetic energy, or take kinetic energy and convert it to electric energy.
Does transformer has high or low efficiency?
Since, transfformer is a Static device (ie. no moving parts in it) hence it is the most efficient machines ever made by man. However, in rotating machines there are various losses like friction and windage, losses in commutator etc. So, yes, Transformers are highly efficient devices.
Why trasformer is static device?
b'coz transformer is not a moving parts so it works on the princeple of mutual induction
What is 3 concentric rotating shafts?
Three concentric and rotating shafts would be known as a contra-rotating device. Currently, several machines like these are being designed, according to the US Patent Office.

Why induction transformer called rotating transformer?
Transformer has windings
Why transformer not rotating?
transformer is not rotating bcoz for rotating rotating magnetic field is required which is produced only when the current is passed through the windings which are displaced physically by 120degrees and phase difference of 120 degrees where as in transformer there is no phsical displacement of 120degrees hence transformer cannot rotate.
Why transformer frequency is constant?
In transformer there is no rotating part.so frequency constant.
What is a static transformer?
It's a transformer that operates with AC current in and out. It's an ordinary transformer, with the term "static" used to differentiate it from rotating transformers, such as motor-generator sets.
What is the definition of commutator?
A commutator is an electrical switch that periodically reverses the current direction in an electric motor or electrical generator. A commutator is a common feature of direct current rotating machines.
What has the author Elias Morshed Sabbagh written?
Elias Morshed Sabbagh has written: 'Unbalance in alternating-current rotating machines' -- subject(s): Electric machinery, Alternating current
What is axial alignment in rotating machines?
Shaft center to center
In which chapter of BS 7671 would you find reference to rotating machines?
55
Why is induction motor called as rotating transformer?
it may be because rotating transformer also have one winding turns while the other remains stationary.because the one that was stationary is the one that accepts signals and the one that was turning is the one who converts he signal into current and distribute it to the motors engine
