Kind Code:
A1
Abstract:
This stator has: a stator core having an outer circumference and an inner circumference, each of which is centered on the axial line, and having a first slot and a second slot which open on the inner circumference; a first coil wound around the stator core in a distributed winding manner and inserted into the first slot; and a second coil wound around the stator core in a distributed winding manner and inserted into the second slot. The length L1 of the first slot in the radial direction centered on the axial direction is longer than the length L2 of the second slot in the radial direction. The diameter D1 of the first coil is larger than the diameter D2 of the second coil.
