Stator assembly with winding sets having hairpins from multiple hairpin layers

An electric machine comprising:

• a stator assembly;
• a rotor assembly rotatable relative to the stator assembly;
• wherein the stator assembly includes:
• a plurality of stator slots defining first, second, third, fourth, fifth and sixth slot layers;
• a plurality of hairpins each having a respective first leg positioned in one of the first, second, third, fourth, fifth and sixth slot layers and a respective second leg positioned in another of the first, second, third, fourth, fifth and sixth slot layers, each of the plurality of hairpins being configured to allow a current to flow from the respective first leg to the respective second leg;
• wherein the plurality of hairpins is divided into first, second, third, fourth, fifth and sixth hairpin layers;
• and
• the plurality of hairpins forms first, second, third and fourth winding sets, each of the first, second, third and fourth winding sets at least partially including the plurality of hairpins from at least two of the first, second, third, fourth, fifth and sixth hairpin layers.
