A stator includes a stator core having a plurality of teeth, an insulator, a plurality of coils, a first region in which distal ends of feeder lines are connected to each other, and a second region in which distal ends of neutral lines are connected to each other. The insulator has inner and outer walls spaced from each other in a radial direction. In a cross section at a gap between two adjacent coils, along a plane including an axis of the stator core, a center of gravity of the first region is positioned above a center of gravity of the second region in an axial direction. B&#x3c;A and C&#x3c;A, where a radial length of the first region is B, a radial length of the second region is C, and a radial length between the inner wall and the outer wall of the insulator is A.

Stator, motor, and compressor

Each of permanent magnets includes a magnet body formed across the radial direction of a rotor core, and a pair of magnet end parts bending toward the outer peripheral side of the magnet body and extending respectively from both ends of the magnet body in the peripheral direction toward the outer edge of the rotor core. Magnetization directions of the magnet end parts and a magnetic pole center line intersect with each other on the outer peripheral side of the magnet body. The inclination angle of each magnetization direction of the magnet end parts with respect to the magnetic pole center line is greater than the inclination angle of a magnetization direction of the magnet body with respect to the magnetic pole center line.
