Abstract
The utility model discloses a stator punching sheet of a miniwatt refrigeration compressor motor, and belongs to the technical field of refrigeration compressor motor parts. The stator punching sheet comprises a yoke portion, two first chamferings, two second chamfering, two mounting holes respectively positioned corresponding to the second chamferings, a central hole and a stator punching sheet groove arranged around the central hole; the diameter D of the central hole is 49mm; the two first chamferings commonly extend to form a protrusion portion; the other mounting hole is positioned on a vertical central line Y-Y' and arranged on the protrusion portion; hole spacing A of the mounting holes close to the second chamferings is 69.6 mm; the hole spacing B between the other mounting hole and the central hole is 45mm. By employing the technical scheme, the motor stator punching sheet material is saved; yoke portion magnetic conductive area utilization rate is high, magnetic density is uniformly distributed, so the motor performance is lifted in certain level; the stator punching sheet of the utility model can satisfy economy demands of the motors of 20-50W.
Description
Technical field
The utility model relates to a kind of stator punching of compressor electric motor, especially relates to a kind of stator punching of small-power compressor for refrigeration motor, belongs to compressor for refrigeration motor part technical field.
Background technology
The power that small-power freezer compressor, ice machine, its motor of water dispenser need is conventionally between 20-50W, and normally adopt in the prior art power, it is 25-80W motor, although its power scope of application of 25-80W motor is large, highly versatile, but the stator punching of manufacturing motor is uneconomical, waste of material is large, the stator punching of this wide range of power motor, there are three installing holes, installing hole spacing dimension is 126.5 * 58.5mm, visible, stator punching overall dimension is larger, and stator punching diameter of bore is larger, is 52mm aperture.
Furtherly, wherein two installing holes are opened in respectively near two jiaos of stator punchings (pitch of holes is 58.5mm), another installing hole is opened in the centre position of other two jiaos of stator punching, this another installing hole is 46.5mm to the distance at stator punching Kong center, installing hole irrational distribution; When wherein two installing holes point to respectively center, stator punching hole, all to aim at stator punching groove, and wherein two installing hole centers divide that to be clipped to the distance of corresponding stator punching groove bottom land less, be 11.55mm, also have, stator punching four rounding of angle arcs are all larger, so cause that stator punching yoke portion magnetic conductive area utilance is low, the close deficiency pockety of magnetic.
In addition, due to these three installing hole irrational distribution, can make that this structural electromotor operational vibration is large, noise is large.
Utility model content
The technical problems to be solved in the utility model is to meet on the basis of motor performance requirement guaranteeing, the stator punching of a kind of stock utilization is high, yoke portion magnetic conductive area utilance the is high power small-power compressor for refrigeration motor between 20-50W is provided.
For solving the problems of the technologies described above, this practicality provides following technical scheme:
A kind of stator punching of small-power compressor for refrigeration motor, comprise yoke portion, two the first chamferings, two the second chamferings, lay respectively at a near installing hole of corresponding the second chamfering, a centre bore, one stator punching groove arranging around described centre bore, and another installing hole, its diameter of described centre bore D is 49mm, described two the first chamferings extend to form a protuberance jointly, described another mounting hole site goes up and is opened in this protuberance position in longitudinal centre line Y-Y ', pitch of holes A between near the installing hole the second chamfering is 69.6mm, another installing hole is 45mm to the pitch of holes B of centre bore.
Above-mentionedly lay respectively near each installing hole corresponding the second chamfering also all with accordingly stator punching tooth portion is corresponding.So increased magnetic conductive area.
The beneficial effects of the utility model are as follows:
Compared with prior art, it is relatively even that the pitch of holes of installing hole distributes, and center-hole diameter dwindled, and makes its overall dimension of full wafer stator punching obtain corresponding dwindling, and saved thus the stator punching material of compressor for refrigeration motor, stator punching has two the second chamferings, be two lay respectively near installing hole corresponding the second chamfering all as much as possible outer moving create conditions, and set up protuberance and offer another installing hole at protuberance place, so be conducive to stator punching and on biserial mould, overlap material punching, the design of protuberance has not only improved material use area effectively, and make the yoke portion magnetic conductive area utilance of stator punching high, magnetic is close to be evenly distributed, so reducing under the condition of stator punching area, not only fully met the basic demand of motor performance, and make motor performance also further obtain lifting to a certain degree, the motor that the utility model stator punching is assembled into has met small-power freezer compressor, refrigeration machine, the economic needs of water dispenser to 20-50W motor, therefore, the utlity model has certain significance of application.
In addition, another installing hole is opened in behind protuberance place, because three installing hole spacing distributions are relatively even, therefore, once after the motor that this stator punching is assembled is installed on compressor, have the advantages that vibrations are little, noise is low.
