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.
What else can I help you with?
Why sheet steel with high silicon content is used in transformer core whereas lower silicon content sheet for rotating machine?
high permeability ,low hysterisis,increased resistivity
What is electrical rotating machine?
MOTOR
Which machine have very less losses in electrical?
Transformer
What is auto transformer stater?
I think you are confusing your terms. The term 'stator' (not 'stater') is used to describe the stationary part of a rotating machine (motor, generator), as opposed to the term 'rotor' which describes the rotating part. No part of an autotransformer is normally described as a 'stator'. An autotransformer has a laminated silicon-steel 'core', around which are placed 'windings'.
How is current controlled in welding transformer?
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
Rotating machine that uses electrical energy?
An electric motor!
How is an alternator different from transformer?
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.
What is the Maximum efficiency machine?
The electric space heater. It's the only common machine that's 100% efficient.
What is a machine that produces electric current?
A generator is a machine that converts mechanical energy into electrical energy, producing electric current. It works on the principle of electromagnetic induction where a coil of wire rotating in a magnetic field creates an electric current.
1908 washing machine?
In 1908, the washing machine underwent significant advancements, with electric models becoming more widely available and popular. These early electric washing machines were typically top-loading and featured basic agitator or rotating drum designs. While these washing machines were more efficient than manual methods, they were still rudimentary compared to modern models.
Why sheet steel with high silicon content is used in transformer core whereas lower silicon content sheet for rotating machine?
high permeability ,low hysterisis,increased resistivity
Is transformer a machine or device?
no a transformer is not an electrical machine. electrical machine is one in which the process of electro-mechanical energy conversion happens e.g motor, generator. therefore mechanical motion is always there in a machine.Engr. Saif Ali Solangisaif.a.khi@gmail.com
What is rotating machine?

What is the difference between manual sewing machine and an electric sewing machine?
An electric sewing machine does it's work by using electricity to move the needle up and down, and rotate the bobbin. The mechanical parts of a manual sewing machine, had to be set in motion by turning a handle, or pedal. An electric sewing machine has an electric motor attached to these rotating parts, by belt or gearing and operated by a foot switch. This makes it less tiring on the arms or feet, you can keep sewing faster and longer.
How does a balancing machine work?
A balancing machine works by mounting the rotating component such as a wheel or rotor onto the machine. The machine measures the imbalance of the component and calculates the amount and location of counterweights needed to balance it. These counterweights are then added to the component to remove the imbalance, ensuring smooth and efficient operation.
Why does a 3 phase transformer produce an alternating flux while a 3 phase induction machine produces rotating flux when fed through 3 phase supply?
In a 3-ph transformer the flux also rotates round the 3 cores but you don't see anything moving.
