motor and transformer working with same principle so why motor rotor was roted and transformer not..

Answer / arjun

for rotation the windings should have phase difference
electrically AS WELL AS spatially , i.e is in space. In
motors we have this condition but not in transformers

motor and transformer working with same principle so why motor rotor was roted and transformer not..

Answer / vikas_04el

SIMPLIFICATION MOTOR PRINCIPLE :- whenever current carring
conductor place in the magnetic field, the electric flux is
cut by it.Now if rotor ckt is short ckted the then current
is flowing.
Now doe to that force (revolving force) occure in the
rotor. And hence motor is rotates.

WHERE AS IN CASE OF TRASFORMER THERE ARE TWO WNDING
1. PRIMARY WNDIG
2. SECONDARY WINDING

WHICH IS BOTH MOUNTED IN SAME CORE(WHICH IS STATIONARY)

NOW IF WE SUPPLY THE PRIMARY WNDING THE EMF IS INDUCED IN
THE SECONDARY WINDING BY ELECTROMAGNETIC EFFECT. THIS EMF
INDUCED BY MUTUALLY INDUCTION PRINCIPLE
SO THERE IS NO RELATIVE EFFECT OCCURE.
THATS WHY MOTOR ROTOR IS ROTATE WHERE AS TRANSFORMER IS NOT
ROTATE

motor and transformer working with same principle so why motor rotor was roted and transformer not..

Answer / kapil bahadure

the motor in which phase displacement created to produced
rotating magmetic field.this rotating magnetic flux cut
with rotor conductor by air gap.
the transformer in which phase displacement not
created.then not produced rotating magnetic field.so
trasformer not roted.

motor and transformer working with same principle so why motor rotor was roted and transformer not..

Answer / nagaraja bagi.m

Motor : When a current carrying Conductor placed in a
magnetic field then the conductor cut the magnetic lines of
forces & emf is induced in it.Motors are having rotating
part.

Transformer : Transformer is a static device so it is not
ratating & it is electrically seperated seperated but
magnetically linked.

Answer / bhabani prasad pradhan.

Transformer is a static device,it works in the "principle
of mutual induction" AND rotor is a rotating device,working
in the "principle of self induction".

motor and transformer working with same principle so why motor rotor was roted and transformer not..

Answer / jitender

Its simple as the output from motor is mechanical form but the o/p of X-mer is in electrical form.To get ant o/p from any system there must be the relative motion b/w the tow parts of motor.

Answer / ravichandran

Transformer is not having rotar so transformer is not
rotating,Motor is having rotat that way is rotating .
