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.
More specific please...
density of transformer is 1.98
Because we're rotating with it
Only the friction between the object and the rotating table will be responsible to keep you off from sliding out on a rotating table.
Static equipment is equipment with no moving parts, such as a steam ejector. Rotating equipment has moving parts. An example of rotating equipment is a compressor.
This microwave has a 12 5/8 in. rotating turntable inside.
Transformer has windings
In transformer there is no rotating part.so frequency constant.
Frictional , rotating losses are not common to transformers and rotating machines. these are specific to rotating machines.
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.
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
b'coz transformer is not a moving parts so it works on the princeple of mutual induction
No. Transformer essentially can step up or step down voltage or provide same voltage across the secondary side. It can not generate voltage on its own. Generator is essentially a rotating device. Transformer is a static device.
Because the electrical parts of a transformer do not move / rotate.
The only motor associated with a transformer is an on-line tap changing mechanism motor! So your question doesn't really make any sense!
An 'alternator' is simply another term for an a.c. generator, that is a rotating machine that generates electrical energy. A 'transformer', on the other hand, is a static machine that changes the levels of voltage -they either step up a voltage or step down a voltage.
In a 3-ph transformer the flux also rotates round the 3 cores but you don't see anything moving.
In case of Alternator, the three phases (RYB) are wound on the stator in a sequential manner (R-Y-B-R-Y-B... so on) As we are aware, the three phases are electrically apart by 120deg. so that by adopting such a stator winding, a rotating magnetic field with synchronous speed (120*freq/no. of poles) is developed. Even an emf is induced in the rotor also, with similar synchronous speed, but owing to large inertia of rotor, it cannot attain synchronous speed and stays standstill.In case of transformer, the three-phase windings are wound on three limbs - on each limb LV winding is wound on the core and then HV winding is wound over the LV winding (for increased efficiency of transformer). Due to this constructional arrangement, a rotating magnetic field is not visualized in transformer, rather mutual inductance comes in to picture.
