Answer / avtar singh

coz it is static device it has no rotatry
part....................

Answer / zain

in motor there is on rotatary part thet is router when
poles of motor make south or north pole the router attarct
with them & as a result rotates.while transformer they work
on mutual induction they didn;t have make any poles or
don't have any rotatry part.thats y....

Answer / ravikumar.g

The motor and transformer works on same princple yes.

But in motor three phase winding genarates Rotateing
magnetic flux it rotates the rotor.

But in the transformer the three phase winding genarates
alternating flux.

On thig is their no roatating part in the transformer.

Answer / kapil

because F=BIL is neutralized in transformer while due to
cylindrical structure motor this force tends to rotate
motor.

Answer / silamparasan p.

Because it is a stationary device so it will not ratate.
That's why the transformer is a most efficiency electrical
machine compare with motors.

Answer / pankaj rana

because motor converts electrical energy into mechanical
energy with rotating parts while transformer transfers
electrical energy from one circuit to another circuit
having all parts stationary.

Answer / sanjivani mhaske

Because in transformer case, Primary & secondary volatge
is in phase whereas in motor case their is 120 degree phase
shift which has rotating magnetic flux tend to rotate rotor.

how to calculate the slowness and fastness of energy meter if we have different kw load for example (0.746 kw and meter rev constant 400 and we calculate the 2 rev in 30 sec) please explain the formula thanks
