Hello khongai

 

I expect that you are referring to the korndorfer auto transformer starter.

 

There are two ways to make an autotransformer starter with one step.One is an open transition starter, and the other is a closed transition starter. The Korndorfer starter is the closed transition starter using a star contactor in the star of the transformer.

 

I will try to get a basic circuit uploaded to the web page in the next day or so.

 

Best regards,

Hello khongai

Have a look at http://www.lmphotonics.com/m_start.htm I think that this plus the circuits above should answer any questions that you have.

If you have specific questions, please feel free to ask.

Hey!!

 

That's some good information. Thanks.

 

But, can you give me an idea how to choose the ratings for contactors used in this Korndorffer starter?
