Abstract
A motor may include a stator with a coil disposed on an inner side thereof, a rotor at least partially surrounded by the coil and having an accommodation space in which a refrigerant for cooling the coil may be accommodated, a shaft connected to the rotor to rotate integrally with the rotor, and a pipe communicating with the accommodation space so that the refrigerant may be introduced from an external source and the refrigerant flows into the accommodation space therethrough.
Claims13
A motor comprising:
- a stator with a coil disposed on an inner side thereof;
- a rotor at least partially surrounded by the coil;
- a shaft connected to the rotor to rotate integrally with the rotor;
- and
- a pipe at least partially inserted into the shaft and through which a refrigerant for cooling the coil flows,
- wherein the pipe rotates integrally with the rotor and the shaft
- wherein the pipe comprises an inlet and an outlet,
- wherein the outlet comprises a first outlet corresponding to an upper end portion of the coil and a second outlet corresponding to a lower end portion of the coil, and each of the first outlet and the second outlet is formed as one or more outlets,
- wherein the first outlet comprises a first outlet hole formed in the first outlet and the second outlet comprises a second outlet hole formed in the second outlet, wherein the first outlet hole and the second outlet hole are configured to communicate with an inlet hole formed in the inlet, and
- wherein the inlet hole, the first outlet hole, and the second outlet hole are exposed to an outside of the shaft and communicate with the outside of the shaft.
