    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 includes a first scroll and a second scroll engaged with the first scroll and configured to perform an orbiting movement. The second scroll forms a compression chamber between the first scroll and the second scroll. The scroll compressor includes a frame positioned opposite the first scroll with the second scroll interposed therebetween. The scroll compressor also includes an oldham ring that has an annular ring portion and a key portion protruding from the ring portion. The key portion is slidably coupled to a key groove provided in the frame or in the second scroll to allow the second scroll to perform an orbiting movement with respect to the first scroll. The scroll compressor also include a reinforcing member coupled to the key portion. The reinforcing member is positioned between the key groove and the key portion.
