  • Publication number: 20220407377
    Abstract: A cooling system is provided. Coil ends protrude outward from a first end of a stator core in a direction along a central axis. An imaginary straight line is orthogonal to both of a central axis of a core body and an axis extending in an up-down direction. Half the coil ends above the imaginary straight line are in a first portion. Each of the segment coils in the first portion includes an outer peripheral surface that faces in a direction opposite from the central axis. The outer peripheral surface of each of the segment coils includes a twisted surface. The direction in which the twisted surface faces becomes closer to the direction facing the stator core as the twisted surface extends toward the first end of the stator core.
