Stator, electric motor, compressor, and air conditioner

A stator comprising:

• a stator core;
• and
• a coil wound around the stator core and including at least one first winding and at least one second winding connected to the at least one first winding in parallel, the at least one second winding being formed of a material different from the at least one first winding, wherein
• the coil includes a coil-end part located outside the stator core,
• the stator satisfies:
• (C1/S1)>(C2/S2)
• where P1 is a straight line that halves a maximum height of the coil-end part from a point of contact of the coil with the stator core in the coil-end part, S1 is a total cross-sectional area on a first side of the coil-end part that is an opposite side of the straight line P1 from the stator core, S2 is a total cross-sectional area on a second side of the coil-end part that is an opposite side of the straight line P1 from the first side, C1 is a total cross-sectional area of the at least one first winding on the first side of the coil-end part, and C2 is a total cross-sectional area of the at least one first winding on the second side of the coil-end part, and
• the stator satisfies:
• ∅
• Al
• ×
• ρ
• Cu
• ρ
• Al
• <
• ∅
• Cu
• where φCu [mm] is a diameter of the first winding, φAl [mm] is a diameter of the second winding, ρCu [Ω·m] is electrical resistivity of the first winding, and ρAl [Ω·m] is electrical resistivity of the second winding.
