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: According to one embodiment, there is provided a motor-operated compressor comprising a rotation shaft, a first scroll configured to perform an orbiting motion and comprising an eccentric coupling portion eccentrically coupled to the rotation shaft, a second scroll coupled to the first scroll to form a pair of compression chambers, a rotor coupled to the rotation shaft, a stator forming an accommodation space configured to accommodate the rotor, and an eccentricity compensation portion configured to compensate for an eccentric displacement of a center of gravity of the rotation shaft, in response to the orbiting motion of the first scroll. The eccentricity compensation portion comprises a first member positioned on one end of the stator and a second member positioned on the rotor adjacent to the first member.
