| 摘要 |
The present invention relates to a motor and, more specifically, to a water-cooled motor capable of improving cooling efficiency by circulating coolant to cool heat generated in a stator. The water-cooled motor, which is an electric motor having a stator and a rotor mounted therein, comprises: an internal housing which is mounted in a hollow shape having a certain length to include a stator fixed and coupled therein and has cooling flow paths formed on the outer surface thereof to circulate coolant; an external housing which has an inlet/output to introduce/discharge the coolant and is adhesively fixed to the outer surface of the internal housing; and end caps which are coupled to opened both ends of the internal housing and the external housing, wherein the multiple cooling flow paths are included by annular partitions which are arranged with regular intervals along the length direction of the internal housing, and the neighboring cooling flow paths are connected to each other through at least one moving path formed on the partition. |
