Abstract
An electric rotating machine is provided which includes a stator in which a coil is so wound as to have an coil end and a coolant channel. The coolant channel has defined therein a flow path through which coolant flows and a flow separator disposed in the flow path and a first and a second coolant outlet. The flow separator works to separate a flow of the coolant into at least a first and a second coolant streams. The first coolant outlet communicates with the first coolant stream, while the second coolant outlet communicates with the second coolant stream. The first and second coolant outlets drain the coolant to different portions of the coil end, thereby cooling almost the whole of the coil end even when the electric rotating machine is tilted undesirably.
