Abstract
According to one embodiment, a stator includes a stator core with slots, and multi-phase segment coils each including coil segments each including a first linear part and a second linear part arranged in different slots and a bridge part, the coil segment formed of a rectangular conductor. An innermost coil segment in the slot is structured with divided segments adhered together. Each divided segment includes a first linear part and a second linear part, and a bridge part, and is formed of a rectangular conductor cross-sectional area of which is smaller than the rectangular conductor of other coil segments. The bridge parts of the divided segments are arranged to cross each other in the radial direction.
