Does the transformer air gap and winding direction have any effect on the output? [Copy link]

This is the structure of the original transformer. Based on this transformer, we have modified the position of the corresponding PIN pins of each winding. Now the direction of input and output is switched from the original side. Do the PINs (1-7) winding toward the outside of the machine need to be changed to PINs (8-14) winding toward the outside of the machine? Does the air side need to be changed to be installed on the 8-14 side?

[Does the air surface need to be installed on the 8-14 side? ]

What is the "air surface"? Does it refer to the "air gap"?

The winding direction affects the same-name terminal, and the air gap affects the inductance. The transformer of the flyback switching power supply must have a certain air gap to make the primary inductance the designed value.
