Abstract
This object is to secure a creepage insulation distance and improve insulation reliability. A stator core is formed as a housing, and is configured such that storage spaces for storing a plurality of segment coils are formed on an inner circumferential side of the housing in an axial direction of the housing and a plurality of the storage spaces is formed at intervals on the inner circumferential side of the housing. A plurality of coil support members is formed as annular members, and supports the plurality of segment coils. The coil support members each include a plurality of through-holes for inserting the segment coils, which is openings connected to the storage spaces, are separately disposed at both ends of the stator core in the axial direction, and each cover the inner circumferential side of the end portion of the stator core in the axial direction.
