Abstract

The utility model discloses a motor stator punching sheet for a refrigeration compressor, which belongs to the technical field of the refrigeration compressor and comprises a stator magnet yoke, an inner hole in the center of the stator magnet yoke and a plurality of stator grooves distributed around the inner hole. The stator grooves are sorted into two groups in a mode that one group consists of one small groove, one middle groove, one big groove, one middle groove and one small groove sequentially and are arranged symmetrically with a symmetry axis. The width of a notch of the stator is 1.32mm. By adopting the structure, the motor stator punching sheet for the refrigeration compressor reduces the working temperature rise of the motor of the compressor. Due to the optimization design of the small notch of the stator, the grooves have less magnetic flux leakage so as to further reduce the working temperature rise of the motor. Under the premise of guaranteeing the same design output power, the motor stator punching sheet for the refrigeration compressor can reduce the amount of superposed stator punching sheets, reduces the power consumption and improves the energy efficiency ratio.

Description

The refrigerant compressor motor stator punching
Technical field
The utility model relates to the improvement of motor stator, belongs to technical field of refrigeration compressors.
Background technology
In prior art, refrigerant compressor is normally used to be single-phase asynchronous motor, its stator punching structure that roughly is square, four jiaos of punching out have the fixing hole of using, comprise yoke, be positioned at the endoporus and the uniform some roads stator slot of ring endoporus of yoke central authorities, make by the silicon steel sheet punching press, for a plurality of punchings axially are stacked into stack of laminations along motor, and clamp with clamping device, thereby the formation stator, the stator slot shape of this stator punching, size is identical, and its groove top all is a circular arc, notch is then for pointing to the bigger semi-closed port of endoporus, the width of this semi-closed port is 1.8-2.0mm, the stator laminating structure of this stator slot design, and slot leakage is many, work temperature rise when being used for compressor electric motor, power consumption is big.
The utility model content
The utility model provides a kind of refrigerant compressor motor stator punching at the deficiency that above-mentioned prior art exists, and adopts this stator punching can make the machine operation temperature rise low, and power consumption is little.
For reaching above-mentioned purpose, solution of the present utility model is as follows:
The refrigerant compressor motor stator punching, comprise stator yoke, be positioned at the endoporus of stator yoke central authorities and around some roads stator slot of arrangement of bores, stator slot takes the shape of the letter U, at the bottom of its bottom land is arc, form semi-enclosed notch at its aperture position, stator slot is one group by sulculus, middle groove, vat, middle groove and sulculus, is ranked into 2 groups altogether, and arrange that axisymmetricly the width of its notch of stator is 1.32mm.
The beneficial effects of the utility model are as follows:
Adopt the 1.32mm width stator rabbet and by little, in, different size stator slot distribution design, reduced the work temperature rise of compressor electric motor, under the prerequisite of same design power, can reduce the quantity of the stator piece of stack, power consumption is less, save electric energy, compared with prior art, embodied progressive of the present utility model.
Description of drawings
Be described in further detail with regard to the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model stator laminating structure schematic diagram;
Embodiment
See also Fig. 1, it is preferred embodiment of the present utility model, refrigerant compressor comprises stator yoke 2, is positioned at the endoporus 3 of stator yoke 2 central authorities and some roads stator slot of arranging around endoporus 3 with motor stator punching 1, and stator slot takes the shape of the letter U, at the bottom of its bottom land is arc, form semi-enclosed notch at its aperture position, stator slot is one group by sulculus 5, middle groove 6, vat 7, middle groove 6 and sulculus 5, is ranked into 2 groups altogether, and arrange that axisymmetricly the width of its notch of stator slot is 1.32mm.
Wherein, the length of stator punching 1 is 110mm, and width is 100.5mm, the aperture 60.6mm of endoporus, stator slot amounts to 24 stator slots by 6,4 sulculuses of 7,4 middle grooves of 16 vats 5 and constitutes, by 1 sulculus, 7,1 middle groove 6 of 6,8 vats of 5,1 middle groove and 1 sulculus 5 is one group, totally 2 groups, arranges axisymmetricly, radius at the bottom of vat 7 arcs is 3.45mm, radius at the bottom of middle groove 6 arcs is 3.17mm, and the radius at the bottom of sulculus 5 arcs is 2.87mm, and the width at the bottom of the arc is greater than the width of notch.
Stator slot by little, in, different distribution of sizes design, reduced the caloric value of motor, and stator sulculus mouth optimal design, slot leakage is few, further reduce the work temperature rise of motor, under the prerequisite that guarantees same design power output, can reduce the quantity of the stator piece of stack, reduce power consumption, improved Energy Efficiency Ratio.
