Description
Technical field
The utility model relates to the punching of a kind of iron-clad stator for motors.
Background technology
The punching of iron-clad stator for motors, it is widely used in the motors such as the interior machine of air conditioner cabinet, dehumidifier, suction top machine.Present this stator punching, as shown in Figure 3, generally comprise stator punching body 1 ', the outline of described stator punching body 1 ' is complete circle; Be arranged at the stator punching groove 2 ' that is used for winding around on the body 1 ', described stator punching groove 2 ' is roughly trapezoidal; The diameter of bore of this stator punching is of a size of 77mm, and the notch of this stator punching groove 2 ' is of a size of 1.6 ~ 1.7mm, and the groove of stator punching groove high (promptly fall trapezoidal height) is of a size of below the 12mm, and the distance between the adjacent two stator punching grooves is 2.0mm; Adopt the stator punching of above-mentioned specification to have disadvantage: 1. fall trapezoidal stator punching groove, because corner angle are more, mellow and full inadequately; The flute profile design is not enough to be optimized, and in the time of can making the motor load operation, motor noise is big; The motor power output is little; And consumed power increases, and greatly reduces electric efficiency like this, increases electric machine temperature rise, the useful life of reducing motor; 2, this stator punching groove area is little, and under the coil turn situation identical with the line footpath, promptly the whole winding cross-sectional area is certain; This stator slot area is more little so, and promptly the space is little, and whole winding area and groove area just are easy to approaching; Be easy to mutual extrusion between the every enamelled wire when coil embeds this stator punching groove like this in the coil, grazing causes damage even broken string; Damage, the result of use of motor thereby influence is known clearly has also strengthened the manufacture difficulty of motor; 3. outline is the stator punching body of complete circle, and materials used is many, increases cost of manufacture, and stock utilization is low.
Summary of the invention
The utility model provides a kind of hole area big to the above-mentioned deficiency of prior art, the iron-clad stator for motors punching that efficient is high, noise is little, temperature rise is low and consumed power is low.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: the punching of a kind of iron-clad stator for motors; Comprise the stator punching body, be arranged at the stator punching groove that is used for winding around on the body, the diameter of bore on the described punching body is 71.5 ~ 72.5mm; Slot opening 1.8 ~ the 2.2mm of described stator punching groove, the groove of stator punching groove high (being the big trapezoidal height of punching groove) is 12.5 ~ 13.5mm, the distance between the adjacent two stator punching grooves is 3 ~ 4mm (also can claim stator punching tooth portion wide size).
Adopt the iron-clad stator for motors punching of said structure, than existing punching, the groove area of its stator punching groove increases; Be that the space is big, very loose in the whole winding embedding stator slot so, avoided mutual extrusion and grazing between the every enamelled wire in the coil; Be not easy broken string when therefore winding coil embeds this stator punching groove; Coil is easy damaged not, and when making the motor load operation, motor noise reduces; The motor power output increases, and consumed power reduces, and improved electric efficiency (improving electric efficiency 6 ~ 8%) greatly, thereby effective energy-saving reduces discharging; Reducing of consumed power, thus effectively reduce electric machine temperature rise, prolonged motor useful life; The groove of the stator punching groove that the diameter of bore combination of employing 71.5 ~ 72.5mm is above-mentioned is high, tooth portion is wide and the slot opening equidimension; Through experimental verification; Than the size of the 77mm of prior art, the power output when not only having improved motor load also reduces the input power (being consumed power) of this moment; Improve electric efficiency 6 ~ 8%, thereby effective energy-saving reduces discharging.
As preferably, the diameter of bore on the described punching body is 72mm; The slot opening of described stator punching groove is 2.0mm, and the groove height of stator punching groove is 13.01mm, and the distance between the adjacent two stator punching grooves is 3.6mm.Adopt the punching of above-mentioned size, designing more, section emulates the advanced, perfection cooperatively interacts.
As preferably, the outer of described stator punching body is provided with four truncation limits, and described four truncation limits evenly distribute on the outer.Adopt said structure, open material thereby reduce, material-saving improves stock utilization more, reduces cost of manufacture.
As preferably, described stator punching groove is semicircle near the end of punching outer, adopts said structure, has increased the area and the mellow and full degree of stator punching groove, thereby makes the coil that twines on it be difficult for broken string, breakage, has effectively guaranteed the result of use of motor.
