<p>PROBLEM TO BE SOLVED: To provide a cooling device of a rotary electric machine which cools a stator while avoiding enlargement of a physical constitution of the rotary electric machine in a radial direction.SOLUTION: A cooling device 30 includes: a refrigerant supply passage 32 which is formed in an input shaft 10 and opens toward a first rotor support member 15; a first refrigerant guide passage 33 which is formed in the first rotor support member 15, communicates with the refrigerant supply passage 32, and opens toward a second rotor support member 16; and a second refrigerant guide passage 34 which is formed in the second rotor support member 16, the second refrigerant guide passage 34 including one end 34a opened toward an opening part of the first refrigerant guide passage 33 and the other end 34b opened toward the stator 13. A portion A of the second rotor support member 16, which faces a coil rotor 11, has insulation properties.</p> |
