The housing shell 100 may include a base shell 110 and a cover shell 160. The base shell 110 and the cover shell 160 are substantially hemispherical, and are coupled to each other to form an enclosed accommodation space therein.

The base shell 110 may include a suction pipe 120, a discharge pipe 130, and a process pipe 140.

The suction pipe 120 allows the refrigerant to flow into the housing shell 100 and can be mounted through the base shell 110. The suction pipe 120 may be separately mounted on the base shell 110 or integrally formed with the base shell 110.

The stator core 210 is made of a metal material and can have a substantially cylindrical shape.

The stator coil 220 generates an electromagnetic force when a voltage is applied from the power supply unit (not shown) to perform an electromagnetic interaction with the stator core 220 and a rotor 240 described later.

The driving unit 200 may further include an insulator 230 disposed between the stator core 210 and the stator coil 220.

The insulator 230 prevents direct contact between the stator core 210 and the stator coil 220. This is because, when the stator coil 220 is in direct contact with the stator core 210, the generation of electromagnetic force from the stator coil 220 may be hindered. To prevent this, the insulator 230 separates the stator core 210 and the stator coil 220 by a predetermined distance from each other.

The driving unit 200 may further include a rotor 240 corresponding to a rotating portion of the driving unit 200 during driving. The rotor 240 is rotatably mounted inside the stator coil 220.
