Abstract: A motor stator has a core and first, second and third hairpin wires. The core has slots, an insertion side and an extension side. Each first hairpin wire has its first hairpin first leg inserted into a third layer of the slots and its first hairpin second leg inserted into a sixth layer of the slots. Each second hairpin wire has its second hairpin first leg inserted into a fourth layer of the slots and its second hairpin second leg inserted into a fifth layer of the slots. Each third hairpin wire has its third hairpin first leg inserted into a first layer of the slots and its third hairpin second leg inserted into a second layer of the slots. At the extension side, a plurality of immediately-adjacent hairpin legs are connected to form first and second winding sets.
