Abstract
The utility model discloses a stator core of a novel shaded pole motor, belonging to the field of motors. The traditional stator core has the defect that manual operations are required during assembly. The stator core provided by the utility model comprises a plurality of overlapped stator punching sheets, and each stator punching sheet comprises an outer ring, an inner ring and a connecting part for connecting the inner ring and the outer ring, wherein the inner ring is of closed type, and the outer ring is provided with openings symmetrically arranged between two adjacent connecting parts. The stator core also comprises bolts, and the bolts penetrate through the openings so as to close the openings. In the utility model, the openings of the stator core are closed by using the bolts, so that the entire magnetic circuit is closed, the phenomenon of magnetic leakages is eliminated, and the motor performance is effectively increased.
Description
Technical field
The utility model belongs to machine field, and is especially relevant with a kind of stator core of novel motor with cup rotor.
Background technology
Stator is the actionless part of motor.Stator is made up of stator core, stator winding and support three parts.Stator core is to be formed by stacking the multi-disc stator punching.
At present, the structure of stator punching is by outer ring, inner ring and be connected inner ring and the connecting portion of outer ring is formed, and the outer ring is an enclosed construction; Inner ring is provided with the opening of symmetry, and stator core is formed in the stack of multi-disc stator punching, and coil is formed by the coil winding machine coiling; And then coil is flush-mounted on the connecting portion of stator core by manual work; Constitute a complete stator, the mode that this kind produced stator exists the needs manual work that coil is flush-mounted in the stator core, so human cost is high.
The utility model content
The purpose of the utility model will overcome above-mentioned defective exactly, and providing a kind of can directly wind the line on stator core, realizes what full-automation was produced, and the good stator core construction of magnetic loop.
For this reason, the utility model adopts following technical scheme: a kind of stator core of novel motor with cup rotor comprises the stator punching that several pieces are overlapping; This stator punching comprises outer ring, inner ring and is connected inner ring and the connecting portion of outer ring, it is characterized in that: the inner ring of described stator punching is closed, and described outer ring is provided with symmetrically arranged opening between two adjacent connecting portions; Described stator core also comprises latch, and this latch is interspersed in described opening, make coil winding machine be wound in copper cash on the stator core after; The outer ring can be sealed; Can realize magnetic circuit closedly, eliminate the leakage field phenomenon, and then improve electric efficiency.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature.
Described connecting portion quantity is 2 integral multiple, and is symmetrical set.
Described stator core can be made 2 utmost points, 4 utmost points, 6 utmost points, 8 utmost point motors.
Described outer ring is positioned at the opening part position and is provided with groove, is convenient to the fixing of latch.
Described groove is semicircle, and described latch is circular, and latch stretches into groove and fits closely.
Described groove can also be square, triangle and polygon, with the latch of described groove fit also can also be square, triangle and polygon.
The utlity model has following beneficial effect: use latch with closure of openings at the opening part of stator core, can make whole magnetic circuit closedly, eliminated the leakage field phenomenon, thereby effectively improved motor performance.
