Description
Technical field
The utility model relates to a kind of motor stator, particularly a kind of stator punching of enamel insulated aluminium wire motor.
Background technology
At present, conventional motor coil winding generally adopts enamel covered wire, along with sharp rising of copper valency; Copper is in that to produce ratio shared on the cost of motor increasing, and in order to reduce cost, some producers are all changing enamel covered wire into enamel insulated aluminium wire at present; But still adopt the structure of enamel covered wire; Because the resistivity of aluminium greater than copper, therefore must guarantee motor performance through the length that increases stator core, production cost is still higher.
The utility model content
The purpose of the utility model is, a kind of motor stator punching is provided.The utility model can not only guarantee motor properties, can also reduce production costs.
The technical scheme of the utility model: a kind of motor stator punching, comprise the punching body, punching body center is provided with a manhole; The inwall of manhole is provided with some punching grooves that are evenly distributed; Described punching groove comprises favourable opposition film trap and little punching groove, and the slot opening of said favourable opposition film trap is 2.1～2.3mm, is 4.5～4.7mm near the groove shoulder breadth degree of notch; The groove height is 12～12.2mm, and the radius of the semi arch of trench bottom is 3.8mm～4mm; The slot opening of said little punching groove is 2.1～2.3mm, is 4.5～4.7mm near the groove shoulder breadth degree of notch, and the groove height is 9.7～9.9mm, and the radius of the semi arch of trench bottom is 3.5mm～3.7mm.
In the aforesaid motor stator punching, the slot opening of said favourable opposition film trap is 2.2mm, is 4.6mm near the groove shoulder breadth degree of notch, and the groove height is 12.1mm, and the radius of the semi arch of trench bottom is 3.89mm.
In the aforesaid motor stator punching, the slot opening of said little punching groove is 2.2mm, is 4.6mm near the groove shoulder breadth degree of notch, and the groove height is 9.8mm, and the radius of the semi arch of trench bottom is 3.59mm.
In the aforesaid motor stator punching, described punching groove has 24, and wherein 16 is little punching groove, and 8 is the favourable opposition film trap.
Compared with prior art; The utility model is distributed on the inwall of manhole through favourable opposition film trap and the little punching groove arrangement mode with 1: 2; The groove depth that extends simultaneously, thus the area of groove increased, and it is comparatively reasonable to make that the motor coil winding distributes; Thereby under the situation of the length that does not increase stator core, just can guarantee the premium properties of motor, also greatly reduce production cost.The utility model also has the enforcement characteristic of simple structure.
