Description
Technical field
The utility model relates to a kind of motor component, the stator punching that especially a kind of 6 utmost point motors are used.
Background technology
The resistivity of aluminium is a lot of greatly than the resistivity of copper, be with aluminium for copper as the electric conductor in the motor, the cross-sectional area of conductor that must increase aluminum steel by a certain percentage is long-pending.But the present copper enamelled wire motor that generally adopts, its punching flute profile and magnetic structure are finalized the design, punching flute profile area less relatively (can't embed and be unfavorable for High-efficient Production in enormous quantities smoothly) with aluminum steel, that magnetic circuit distributes is uneven relatively (replacing copper cash local magnetic circuit supersaturation can occur and local magnetic circuit magnetic flux density is low excessively with aluminum steel), can't satisfy the production needs of electric machine with aluminium winding.
Summary of the invention
The utility model provides a kind of reasonable in design, 6 utmost point motor stator punchings with enough big groove area.
A kind of stator punching of 6 utmost point motors, the external diameter of stator punching is 1.5～1.7 with the internal diameter ratio, and the groove height is 1.57～3.3 with the yoke height ratio, and the groove height is 0.16～0.26 with the internal diameter ratio.
Stator punching comprises between several stator slots, adjacent stators groove and is provided with the punching tooth in the utility model, and the punching tooth is parallel teeth or is essentially parallel teeth.
The stator punching internal diameter of the motor of different model is different, but relevant design standard according to existing motor, after number of poles, the stator punching external diameter of motor were determined, the internal diameter of stator punching determined that also promptly there is corresponding relation in the internal diameter of stator punching with number of poles, the stator outer diameter of motor.
The utility model is at 6 utmost point motors, the prior art standard is improved, keep the original external diameter of stator punching constant, the stator punching internal diameter is dwindled, along with dwindling of stator punching internal diameter, the radially stator punching center elongation of the top of the punching tooth between the adjacent stators groove makes the area of stator slot be enlarged to 1.3～1.8 times of original area, preferred 1.5 times.The original area of stator slot is after number of poles, the stator outer diameter of motor determined, the area of stator slot in the stator punching of primary standard.After the internal diameter of stator punching dwindled, the external diameter of rotor punching is also corresponding to be dwindled.
In order to make the area of stator slot be enlarged to 1.3～1.8 times of original area, except the internal diameter with the stator punching of primary standard dwindles, can also simultaneously the bottom of described stator slot be expanded to the stator punching excircle, promptly reduce the yoke height, the yoke height is decreased to 0.75～0.95 times of primary standard.
It is aluminum steel that the utility model also provides the interior enamelled wire of 6 utmost point motors, particularly motor that are provided with described stator punching.
The utility model 6 utmost point motor stator punchings provide enough big stator punching groove area, help embedding the bigger aluminium enamel-covered wire of sectional area; The punching structure of uniform Design, its stator teeth and yoke portion magnetic flux density, rotor tooth portion and the reasonable relative equilibrium of yoke portion magnetic flux distribution help reducing the iron loss of punching, reduce that the motor feels hot, reduce winding temperature rise.In addition, adopt the electric machine with aluminium winding of the utility model punching structural design also to have power factor height, air gap flux density is low, electromagnetic noise is little characteristics.The utility model, for generalization, the seriation that realizes product component, the internal diameter of stator punching external diameter and rotor punching is identical with the punching of corresponding standard specification.Like this, related components such as electric machine stand, end cap, rotating shaft, bearing exterior and interior cover, bearing and frock clamp can be general mutually with ordinary copper enamelled wire motor, are convenient to organize the input of producing in batches and reducing electric machine with aluminium winding project in the enterprise to greatest extent.
Description of drawings
Fig. 1 is 6 utmost point stator laminating structure of motor schematic diagrames in the existing national standard;
Fig. 2 is the utility model 6 utmost point stator laminating structure of motor schematic diagrames;
Embodiment
Referring to accompanying drawing, D represents the stator punching external diameter among the figure; D represents the stator punching internal diameter; H1 represents stator punching groove height; H2 represents stator punching yoke height, and CK is the punching groove bottom width, and CK/6 represents that this segment distance is the sixth of CK (punching groove bottom width).
Stator punching comprises between several stator slots, adjacent stators groove and is provided with the punching tooth in the utility model, and the punching tooth is parallel teeth or is essentially parallel teeth.
It in the table 1 contrast of existing common 6 utmost point motor stator punching sizes and the utility model motor stator punching size.
Table 1
| Parameter | Existing common 6 utmost point motor stator punching sizes | The utility model motor stator punching size |
| External diameter/internal diameter | 1.3～1.55 | 1.5～1.7 |
| Groove height/yoke height | 0.8～1.56 | 1.57～3.3 |
| Groove height/internal diameter | 0.09～0.157 | 0.16～0.26 |
As can be seen after the number of poles (6 utmost point) of motor, stator outer diameter are determined, the internal diameter of the utility model electric machine with aluminium winding stator punching is smaller, the high increasing of groove, groove is high and the yoke height ratio strengthens in the table 1.
Along with dwindling of stator punching internal diameter, the radially stator punching center elongation of the top of the punching tooth between the adjacent stators groove makes the area of stator slot strengthen.
Existing standard stator punching external diameter is 130 millimeters among Fig. 1,86 millimeters of stator punching internal diameters, and external diameter/internal diameter=1.511 then, the utility model electric machine with aluminium winding stator punching external diameter is 130 millimeters among Fig. 2, and the stator punching internal diameter is contracted to 81 millimeters, then external diameter/internal diameter=1.605.
Existing standard stator punching groove is high 13.33 millimeters among Fig. 1, then groove height/internal diameter=0.155; The utility model electric machine with aluminium winding stator punching groove is high 17.8 millimeters among Fig. 2, then groove height/internal diameter=0.2197.
Existing standard stator punching yoke is high 8.67 millimeters among Fig. 1, then groove height/yoke height=1.54; The utility model electric machine with aluminium winding stator punching yoke is high 6.7 millimeters among Fig. 2, then groove height/yoke height=2.657.
The utility model stator laminating structure of motor provides enough big stator punching groove area, helps embedding the bigger aluminium enamel-covered wire of sectional area;
