Without going too in-dpeth:

Wye (also called Y or star) has coils in a Y formation with the motor wires coming out the three ends of the Y. The center is a common point, but there is no wire here.

Delta (also called D or triangle) has coils arranged in a triangle formation with the motor wires coming out the points.

Wye has 1.73x lower kv than a Delta of the same wind count.

If you want more detail, a search will turn up the various discussions on the topic.
