The permanent magnet (2) is arranged so that its inner circumferential surface is in contact with the outer circumferential surface of the yoke (3), and its outer circumferential surface is kept at a predetermined magnetic gap with respect to the inner circumferential surface of the stator (6). There is. York (3)
The permanent magnet (2) and the permanent magnet (2) are usually fixed using adhesive, etc., but when the rotor rotates at high speed, the permanent magnet (2)
Since there is a risk that the permanent magnet (2) may be scattered due to centrifugal force, a reinforcing member (1) is generally attached to the outer periphery of the permanent magnet (2).

余分なスペースを設ける必要があり、圧縮機全体の形状
は縦長状となる為、結果的に圧縮機収納スペースが大き
くなる。(2) Since the electric motor part is cylindrical, it is necessary to provide extra space for the coil end (7) which protrudes further in the axial direction from the end face of the stator (6), and the overall shape of the compressor is vertically elongated. As a result, the compressor storage space becomes larger.

以下にすることができない。(4) Since the rotor is cylindrical, the axial length of the rotor tends to be longer than the outer diameter, and therefore the magnetism at the free end of the shaft (8) that protrudes relatively long from the cantilevered support part. Because non-uniformity in physical and mechanical gap lengths is likely to occur,
In order to stabilize this as much as possible, it is generally necessary to increase the axial length of the bearing (9). the result,
The lubrication of the lubricating oil in the bearing becomes poor, and the rotation speed cannot be kept below a certain level.
