Abstract
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<A and C<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.
