Abstract
An electric rotating machine includes a rotor, a stator in which a coil is so wound as to have an coil end, and a coolant supply pipe. The coolant supply pipe lies with a length thereof extending substantially parallel to an axis of rotation of the rotor and is disposed above the stator in a direction of gravitational force. The coolant supply pipe has a first and a second coolant outlet through which coolant is to be emitted to the coil end. The first and the second coolant outlets are 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. This enables the coolant to be emitted to almost the whole of the coil end even when the electric rotating machine is titled in a direction in which the rotor turns.
