| 摘要 | A motor includes: a rotor including an output shaft; a stator provided with a coil wound around the stator; and a casing configured to accommodate the rotor and the stator and to contain a coolant liquid therein, wherein skews are formed in at least one of the rotor and the stator. A hollow portion extending an axial direction is formed in the output shaft. The hollow portion includes an opening that opens in the casing at an end surface of the output shaft where a liquid surface of the coolant liquid is relatively higher due to rotation of the rotor and that communicates with the casing near an end opposite to the end surface. | ||
