Title:
Rotation electrical machinery
Document Type and Number:
Japanese Patent JP6102203
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary electric machine which can, for example, supply liquid to a coil end part with less inconvenience.SOLUTION: A rotary electric machine, for example, includes: a case; a shaft which is provided rotatably in the case and provided with a liquid passage extending in an axial direction of the rotation and a discharge port discharging liquid to the outer side in a radial direction of the rotation from the liquid passage; a rotor which integrally rotates with the shaft in the case; and a stator which is positioned on the outer peripheral side of the rotor in the case and includes a core and a coil wound around the core. The discharge port is opened toward a coil end part projecting in the axial direction from the core of the coil and includes an expansion part which expands toward the outer side in the radial direction.
