An Auto transformer motor starter is a device intended to start AC asynchronous motors, instead of connecting the electric motor directly to the electrical grid, it will connect it to the grid in more than just one step.
Hence, it will behave as an electro mechanical soft starter.
Although it is the "older" method of starting motors, it is still widely used due to its simplicity.
The list of parts needed to "make" an "Auto Transformer Motor Starter" is composed from:
1. Auto transformer itself
2. 3 contactor (electrically sized to fit the motor)
3. Two timers, defining when the contactors will "close".

Auto transformer for a single phase motor starter?
Nah doesnt exist
How do you start a motor without a starter?
By the use of auto transformer and bridge rectifier we can start dc motor.
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
Why auto transformer is lighter than conventional type?
because the copper is saved in the auto transformer that is the ratio of weights of copper in auto transformer to normal transformer is (1-(1/a)) where a is transformer ratio
What is Auto transformer and ordinary transformer?
auto transformer is a one winding transformer which is are used for step up and step down voltage without chang its power and friquncy
What are the advantages of double wound transformer over a auto transformer?
The difference between a double wound step up transformer and an auto transformer is the double wound on the step up transformer and the single wound on the auto transformer.
What does auto in autotransformer stands for?
"Auto" refers to the single winding used an auto transformer.
How do you start a DC motor if there is no 3 point starter?
By the use of auto transformer and bridge rectifier we can start dc motor.
What type of transformer has only a single winding?
the auto transformer is the one winding transformer. it ismaily used in practical purpose.
Where can one purchase an Auto Transformer?
One can purchase an Auto Transformer from websites like Mastech Power Supply, Amazon, Ali Express, RS-Online, eBay, Foster Transformer, Farnell and Alibaba.
Why can auto transformer be dangerous?
(An auto-transformer can be dangerous because the primary is not electrically isolated from the secondary. If the auto-transformer is connected to mains power, this is the equivalent of sticking your fingers directly in the wall plug; not a good idea!) aka deceptacons like megatron will kill you.
How to fix a maximum voltage to home appliances?
by using auto transformer or auto stablizers
