Electric rotating machine with cooling mechanism

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 an end of the stator in an axial direction of the stator;
• a coolant channel which has defined therein a flow path through which coolant flows;
• a coolant supplying mechanism which supplies the coolant to the coolant channel;
• a flow separator disposed in the coolant channel, the flow separator working to separate a flow of the coolant into at least two streams;
• and
• a first and a second outlet, the first outlet communicating with a first coolant stream that is one of the two streams, as produced by the flow separator, the second outlet communicating with a second coolant stream that is the other of the two streams, the first and second outlets draining the coolant to different portions of the coil end, and
• wherein the flow separator has a stopper wall to stop the first coolant stream to create a pool of the coolant to which the first outlet opens.
