ROTATING ELECTRIC MACHINE |
| 摘要 |
A coolant flow path structure which cools a rotor is configured of a first coolant flow path forming a radial coolant flow path of the rotor and a second coolant flow path communicating with the first coolant flow path and forming an axial coolant flow path of the rotor, and a negative pressure structure, which brings an exist of the coolant flow path structure into a negative pressure as a result of a rotation of the rotor, is provided at the exit of the second coolant flow path. |

1. A rotating electric machine comprising:
a coolant flow path structure and a negative pressure structure, wherein the coolant flow path structure, which cools a rotor configured of a rotor core and end plates provided at both axial ends of the rotor core, is configured of a first coolant flow path forming a radial coolant flow path of the rotor and a second coolant flow path communicating with the first coolant flow path and forming an axial coolant flow path of the rotor, and wherein the negative pressure structure, which brings an exit of the coolant flow path structure into a negative pressure as a result of a rotation of the rotor, is provided at the exit of the second coolant flow path. |
