Rotary electric machine having stator coolant passage means

A rotary electric machine mounted on a vehicle, comprising:

• a stator including a stator core and an armature coil that is wound around the stator core and has a coil end protruding from the stator core in an axial direction;
• a rotor arranged opposite to the stator core;
• a housing supporting the stator and the rotor;
• and
• a stator coolant passage means provided radially inside of the housing and radially outside of the stator core, the stator coolant passage means having a damping member and a stator coolant tube defining a stator coolant passage for flowing coolant therethrough, the damping member having a part disposed radially outside the stator coolant passage, wherein the damping member includes a pair of plates, at least one of plates has a groove on a surface thereof for defining the stator coolant passage by being bonded to each other.
