A true autotransformer consists of one, tapped, winding. For a step-down transformer, part of the winding is in series with the supply and the other part is common to both the supply and the load. For a step-up autotransformer, part of the winding is in series with the load, while the other part is common to both supply and load.
But you can also use a mutual transformer as an autotransformer, by connecting the two windings in series and, then, described as above.

What is single phase autotransformer?
An autotransformer is a transformer with at least two windings where a part of one winding (the common winding) is shared between both primary and secondary outputs.
Why a two winding transformer is used instead of single winding transformer?
You need two windings because that is the purpose of the transformer - to convert one voltage into another. If there were only one winding, it would be an inductor, or a special case called an autotransformer, but that is still "sort of" two windings.AnswerThe major advantage of a two-winding transformer (a 'mutual transformer') over a single-winding transformer (an 'autotransformer') is that a two-winding transformer provides electrical isolation between the secondary and primary circuits. This is very important for safety reasons and there are many circumstances in which the use of an autotransformer is not permitted.

What is the purpose of auto transformer?
Helps with the starting of large electric motors.AnswerAn autotransformer is a transformer with a single winding, rather than two separate windings. It can be used as a step-up or as a step-down transformer, provided there is no requirement for electrically-isolating the secondary circuit from the primary circuit.
The windings of an AC motor are called?
Windings
What is single phase autotransformer?
An autotransformer is a transformer with at least two windings where a part of one winding (the common winding) is shared between both primary and secondary outputs.
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'.

Conversion of 2-winding transformer into auto transformer?
Yes, you can use a mutual (2-winding) transformer as an autotransformer, by connecting the two windings in series. For example, if you have a 240:120 V transformer, connecting the two windings in series and supplying the 240-V winding with 240 V can give you a secondary voltage of 360 V. But you must take into account the polarity of the transformer, and realise its capacity will change.
How many coils does a autotransformer have?
only single coil is use as a primary and secondary coil in a auto transformer.
