Abstract:
1. An electric rotating machine comprising: a rotor; a rotating shaft which is to be rotated by the rotor; a stator which faces a circumference of the rotor, the stator having a coil which is so wound as to have coil ends extending outside ends of the stator in an axial direction of the stator; a coolant supplying mechanism which supplies coolant; a coolant supply cylindrical member through which the coolant, as supplied from the coolant supplying mechanism, flows, the coolant supply cylindrical member having a length extending substantially parallel to an axis of rotation of the rotor and being disposed above the stator in a direction of gravitational force; and a first and a second coolant outlet which are formed in the length of the coolant supply cylindrical member and through which the coolant is to be emitted to a coil end, the first and the second coolant outlets being so oriented as to direct streams of the coolant to a first area and a second area of the coil end which are different in location from each other, wherein the coolant supply cylindrical member lies with the length thereof being offset in a direction perpendicular to the direction of gravitational force from a plane extending through the axis of rotation of the rotor in the direction of gravitational force.
