Description
Technical field
The utility model relates to technical field of motors, more particularly to a kind of submersible motor stator iron core.
Background technique
Currently, submersible electric motor is not required to diversion before having small in size, light-weight, starting, limit by suction, do not needed separately
If pump house, easy to install and use, reliable performance, efficiency is higher, it is cheap, can investment reduction the advantages that, can be used as various
The mating power source of submarine mechanical.
However, submersible motor is due to design feature, so that stator core pressing process is stacked into stator in stator punching
It is carried out after seat, this process is higher to the required precision of out frame inside dimension, since submersible motor is usually designed to elongated knot
Structure causes the length and diameter of out frame bigger, increases the difficulty of out frame inner surface processing, and inner circle is processed into
This is higher.
Therefore, how to provide a kind of submersible motor stator iron core for being able to solve the above problem be those skilled in the art urgently
Problem to be solved.
Summary of the invention
In view of this, the present invention provides a kind of submersible motor stator iron cores, solve permanent-magnet water-submersible electric machine stator iron
Core is piled up, a series of problems of press fitting and subsequent installation.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of submersible motor stator iron core, comprising: stator punching, out frame and retainingf key；
Successively closed assembly forms stator punching group to multiple stator punchings, and the stator punching group is located at the out frame
Inside and the stator punching group be fixedly connected with the inner wall of the out frame by the retainingf key.
Have the beneficial effect that stator punching is mounted on inside out frame using above-mentioned apparatus, through retainingf key and stator
Seat is fixed, the stacking of permanent-magnet water-submersible electric machine stator core, compacting and installation process can be smoothly completed, to out frame inner surface
Requirement on machining accuracy is not high.
Preferably, multiple stator slots are offered at the stator punching inner diameter edge, and the stator slot is along the stator
The internal diameter of punching is arranged successively.
Preferably, the stator punching with a thickness of 0.25-0.6mm.
It can be seen via above technical scheme that compared with prior art, the utility model, which discloses, provides a kind of diving electricity
The quantity of machine stator iron core, stator punching superposition can be chosen according to the height of real electrical machinery, flexible and efficient；It can smoothly complete
The stacking of submersible motor stator iron core, compacting and installation process, it is not high to the requirement on machining accuracy of out frame inner surface, simplify
Processing and installation process, improve production efficiency, reduce production cost.

Specifically, the material of stator punching 1 can be silicon steel sheet, the material of out frame 2 can be 304 steel, stator punching
The quantity of piece superposition can be chosen according to the height of real electrical machinery.
In a specific embodiment, multiple stator slots 11, and stator slot 11 are offered at 1 inner diameter edge of stator punching
Internal diameter along stator punching 1 is uniformly arranged successively.
Specifically, the quantity of stator slot 11 can be 24, it is evenly distributed at inner diameter edge, reduces flux loss.
In a specific embodiment, stator punching 1 with a thickness of 0.25-0.6mm.
Specifically, the thickness of stator punching 1 can also be any one of 0.25mm, 0.3mm and 0.5mm.
The submersible motor stator core structure of the utility model is piled up at same direction during installation, by stator punching to finger
It is fixed highly to penetrate stator retainingf key to guarantee that stator punching move, after hydraulic press is compacted, by stator punching and retainingf key
It is installed to the designated position of out frame inner wall, and is welded and fixed.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.For device disclosed in embodiment
For, since it is corresponded to the methods disclosed in the examples, so being described relatively simple, related place is said referring to method part
