From electric machine structure, separation layer can be divided into two kinds of integral type and detachable types.The stator iron core that does not change original motor of integral type, just its groove contract is taken out, be processed into the shape of separation layer among Fig. 1 (*) after using resin material (and reinforcing filler) injection moulding or casting then, so the tooth portion that exceeds coil of its stator iron core just becomes an integral body with resin-bonded, so there is double identity in the tooth portion of stator iron core, it is the part (can not cause the variation of electrical properties) of former iron core, be again a component part of this airtight member of separation layer, separation layer and stator iron core are an integral body on physical arrangement.

Detachable type separation layer and stator coil and corresponding iron core partly are discerptible, tooth portion with former stator iron core removes a bit of earlier, make the magnetic conduction bar according to the shape and size of the tooth portion that removes then, be processed into the separation layer of Fig. 4 shape by mould with resin material (and reinforcing filler) injection moulding or casting.Separation layer plays double effect the first, and it is the part of hermetically sealed can; The second, though its magnetic conduction bar is to be divided into two bodies with stator iron core physically, on electromagnetic performance, constituted an integral body.It is convenient that this structure changes, keeps in repair coil.

The locking system of compressor 5 is illustrated in conjunction with the accompanying drawings, and separation layer * combines with the front cover 7 of motor, and realizes sealing by adherent 17, constitutes locking system with sealed tank cap 1 again.6 is seal ring.

Embodiments of the invention are illustrated in conjunction with the accompanying drawings.

Fig. 1 is vertical cut-away view of compressor, Fig. 2 is the k-k sectional drawing of integral type separation layer compressor map 1, the integral type separation layer does not change the stator iron core of original motor, just its groove contract is taken out, use resin material (and reinforcing filler) injection moulding or casting to be processed into the shape of separation layer among Fig. 1 (*) then, so the tooth portion that exceeds coil of its stator iron core just becomes an integral body with resin-bonded, so there is double identity in the tooth portion of stator iron core, it is the part (can not cause the variation of electrical properties) of former iron core, be again a component part of this airtight member of separation layer, separation layer and stator iron core are an integral body on physical arrangement.Separation layer not only is connected as a single entity with iron core but also also combines with coil, so enough intensity is arranged.Separation layer is formed by 15 and 16, and the 15th, the magnetic gap bar of separation layer, the material of it and tank body is the same, by magnetic conduction, material non-conductive, that intensity is higher are not made (considering that from economize on electricity 15 can use some magnetic materials).The 16th, the magnetic conduction bar of separation layer, in fact it is exactly the tooth portion of original motor stator iron core, and 16 to add 11 be exactly the iron core of stator, and iron core does not have any variation, and the magnetic conduction bar has double identity: being the part of separation layer, is again the tooth portion of original motor stator iron core.Front cover 7 requires to have preferably to cooperate with the junction plane A of separation layer *, and realizes sealing by adherent 17, constitutes locking system with sealed tank cap 1 seal ring 6 again.The power that supports fore bearing is provided by end cap 7, and the power that supports rear bearing 12 is provided by rear end cover 13, and 13 by the be locked end support rear bearing 12 of separation layer of B face.
