Abstract: A wound rotor motor is provided, in which a rotary shaft is arranged in the vertical direction, to immerse lower coil portions of a stator and a rotor in cooling oil, thereby improving the cooling effect beyond that of a conventional configuration, in which lower coil portions are partially immersed, and consequently decreasing the capacity of an oil pump. A wound rotor motor is provided, in which a rotary shaft is arranged in the vertical direction and has therein a flow passage, through which cooling oil moves up from the region below the rotor and is sprayed to the region above the rotor by centrifugal force generated by rotation of the rotor, thereby enhancing the motor-cooling effect, decreasing the frictional loss of the rotor due to the cooling oil, and consequently improving the operational efficiency of the motor.
