PURPOSE: A motor cooling apparatus is provided to efficiently control the heat of a motor by installing a water-cooling apparatus outside a motor case. CONSTITUTION: A stator(102) comprises a stator coil(101) occurring magnetic force. A bearing(106) smoothly rotates a rotary shaft. A frame(107) is connected to stator through pressure. A bracket(108) is installed in both ends of the frame. A jacket divides a cylindrical space(211) having a cross section of a ring shape. The cylindrical space is filled with cooling water. A circulating pump is installed inside a water tank(220). A cooling water inflow opening(213) and a cooling water outlet(214) which are communicated with the cylindrical space are installed in the jacket. |
