Detailed Description

The utility model is further described below in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the implementation of the utility model easy to understand.

As can be seen from fig. 1, the utility model relates to a permanent magnet roller motor stator, which comprises a stator main body 1 and a bearing seat 4, wherein a bushing 3 is welded on the inner wall of the stator main body, the bushing is formed by processing a 304 stainless steel plate with the thickness of 0.68mm, the size is different according to different stator specifications, and the inner surface of the bushing is tightly attached to the outer surface of the bearing seat. As can be seen from fig. 2, ribs 8 which are distributed at equal intervals in a staggered manner are welded on the outer surface of the bearing seat, the ribs are 30mm wide and 15mm thick, grooves for flowing cooling water are formed on the outer surface of the bearing seat by the ribs, and the two ends of the bushing are sealed by O-shaped rings. The bearing seat is provided with an inlet 6 and an outlet 7 which are communicated with the groove, and the inlet and the outlet are respectively connected with a cooling circulating water pipe.

In order to ensure that the lining is in complete contact with the inner wall of the stator, a layer Maxtor of heat conduction paste 2 is uniformly coated between the lining and the inner wall of the stator, and the thickness is 0.3mm.

The preparation process of the permanent magnet roller motor stator comprises the following steps:

1. Firstly, uniformly coating a layer of Maxtor heat conduction paste with the thickness of about 0.3mm on the inner wall of the processed stator of the permanent magnet roller motor;

2. Then, a stainless steel bushing is paved on the inner wall of the stator, and the stator is fixed by a special tool and is tightly attached to the heat conducting paste;

3. laser fusion welding interfaces and two ends of the bushing;

4. polishing the welding part to ensure that the welding part is smooth and flat and has no bulge;

5. and (3) sleeving a bearing seat, performing a water pressure test, and checking whether the stator has leakage or not.

When the permanent magnet roller motor stator works, the grooves on the outer surface of the bearing seat are filled with flowing cooling water, the cooling water flows to take away heat, the heat conducting paste ensures the heat conducting effect, and an air cooling device is not needed to be additionally arranged, so that the noise is low, the occupied space is small, and the heat conducting effect is good.
