| 摘要 |
The present invention relates to a stator cooling flow path type electric motor which comprises: a stator (1) on which a coil is wound; a rotor (20) having a magnet mounted therein; and a flow path line (10) accommodated in an inner circumference of the stator (1) and configured to cool heat generated in the stator (1) and the rotor (20) by circulating a cooling fluid, thereby drastically increasing cooling efficiency with regard to a magnet in the motor. Especially, a flow path is installed in a notching portion of a stator teeth (5-2) so that an increase of a gap length, which causes reduction of torque, does not occur even under a lack of a space inside the motor. |
