  2. I suppose to be fair, any of our attempts in Mandarin might be just as
    abrupt :)

    | and the equilateral triangle symbol is usually known as "mesh" in US and
    | "delta" in British.

    I've never heard of it as "mesh" in US or anywhere. Every description of
    it in US is "delta" or "closed delta". I cannot recall any other terms
    being used for other countries, either.


    | You might start by searching for "wye-mesh starter" and "star-delta starter"
    | and combinations thereof..

    Like "wye-delta starter" for US references.
     

  4. I also have never heard the term "mesh", nor can I think of how it
    might possibly relate. Please explain.
     
  5. "Part Y" makes no sense whatsoever. There is Y-Delta starting and
    there is "Part Winding" starting. Are you getting Part Winding
    confused as "part Y" perhaps?

    I've been wondering about that. Maybe "part Y" means 2 legs of 3 phase?
    Or maybe he means part of the time is wye connected then switch to delta
    for full run when the motor is up to an appropriate speed.
