Abstract: The present disclosure provides a motor part comprising a bobbin part comprising a plurality of coils housed therein, a first insulation part adjacent to an inner circumferential surface of the motor chamber, and a second insulation part spaced a predetermined distance from the first insulation part. The plurality of coils are housed in a coil housing spare part formed between the first insulation part and the second insulation part. The first insulation part is located between the inner circumferential surface of the motor chamber and the plurality of coils. The plurality of coils are located adjacent to the second insulation part. Accordingly, insulation caused by separation from the inner circumferential surface of the motor chamber and insulation caused by the first insulation part may be expected. The insulation may be achieved by the plurality of coils being housed in the bobbin part.

Abstract: A scroll compressor is disclosed. The scroll compressor has a housing including an accommodation space, an inlet port on one side of the housing in a length-wise direction of the housing, and a discharge port on another side of the housing in the length-wise direction of the housing. The scroll compressor also has a motor disposed in the accommodation space, a fixed scroll disposed in the accommodation space, and an orbiting scroll disposed between the motor and the fixed scroll. The fixed scroll may be closer to the discharge port than to the motor, and the orbiting scroll module may be engaged with the fixed scroll to form a compression chamber.
