Transformer means transfer of enery from one corcuit to
another.so the t/f is not rotating.

Answer / vijay balu raskar

Transformer is transfer electrical energy from one circuit
to another circuit. Rotation is not mandatory to transfer
energy. For transformation rotation is not required in
transformer as required in motor to rotate.

Answer / jadhav babu

as we know that rotating parts will emit more losses n less
efficiency so transformer is so designed to transfer
electricity from one place to another without any loss and
transformer does'nt have shaft or any rotating part to
rotate like motor

Answer / n.a. abbu

Rotation or motion required only to cut magnetic lines nearby coils or windings. But in transformer case we are using A.C. supply to transfer power from one circuit to other circuit. We know in A.c both magnitude and direction changing by nature. Therefore no need of any motion or rotation to cut magnetic lines to induce e.m.f in nearby coils say secondary.

Answer / ramesh

even three phase supply given to a transformer it does not set up any r.m.f as winding is concentrated unlike induction motor (distributed wdg).There must be r.m.f then only transformer rotate.if transformer wdg changed to distributed wdg with 120 deg electrical displacement surely it will rotate

does frequency affects the load? if yes elaborate it.
