- the seal plate 28 cuts between the compressor housing 20 and the motor stator 24 and is in close contact with the compressor side of the outer sleeve 26.
- the mold member 30 of the motor stator 24 has the stator core 24a and the stator winding 24b embedded therein, and the outer sleeve 26 is formed of the mold member 24.
- a liquid-tight water-cooling jacket 26b is formed between the outer peripheral surface and the inner surface of the bearing housing 16 and between the bearing housing and molded with the water-cooling jacket 26b that does not use part of the compressed air for cooling.
- the outer peripheral surface of the member 30 is directly cooled, and the stator core 24a and the stator winding 24b can be efficiently cooled through the mold member 30 having high thermal conductivity.
- the mold member 30 has the heat insulating layer 32 in close contact with the inner surface (that is, the surface facing the inner side in the radial direction) surrounding the motor rotor 22 and the outer surface in the axial direction (that is, the surface facing the axial direction). Heat input from the presser wheel 14 and the motor rotor 22 can be reduced.
- the mold member 30 includes a hollow cylindrical portion 30a made of a thermally conductive resin in which a stator core 24a is embedded, and a stator winding 24b in contact with both axial ends of the hollow cylindrical portion 30a.
- the outer sleeve 26 is composed of an outward flange 30b made of thermally conductive grease embedded in the outer sleeve 26.
- the contact area force between the mold member 30 and the outer sleeve 26 is the amount of contact area between the axial inner surface of the outward flange 30b of the mold member 30 and the inner surface (surface facing the axial direction) of the outer sleeve 26 in contact therewith. Only increase. Due to this increase in contact area, heat transfer between the mold member 30 constituting the motor stator 24 and the outer sleeve 26 constituting the water cooling jacket 26b can be greatly improved. This effect can be obtained even if the mold member 30 is not made of resin. That is, according to the present invention, the mold member 30 does not have to be made of resin.
- the cooling water space provided in the outer sleeve 26 serving as a water cooling jacket (that is, the space through which the cooling water flows) is formed inside the outer sleeve 26 so as not to be exposed outside the outer sleeve 26. But! /.
- the cooling performance of the motor stator 24 can be improved without reducing the compressor efficiency.
- the outward flange portion 30b has a portion positioned radially outward from the hollow cylindrical portion 30a. Therefore, the stator winding 24b can also be arranged in this portion (see, for example, FIG. 5), and the number of stator windings 24b can be increased accordingly.
