Abstract
The utility model discloses a stator lamination for a motor of a wind generator, wherein the stator lamination is circular and comprises a circular lamination body, the periphery of the lamination body is uniformly provided with a plurality of tooth grooves used for coiling a stator coil, and between every two tooth grooves there is provided a tooth portion; each tooth groove comprises a bottom edge, two symmetrical side edges extending along both ends of the bottom edge in an inclined and upper direction, and two symmetrical top edges extending respectively along the top points of the two side edges; and between the two top edges there is provided a groove opening, the bottom edge, the side edges and the top edges are respectively a straight line, the angles included by the side edges and the bottom edge are 75-85 DEG, the angles included by the top edges and the bottom edge are 10-20 DEG, the width of the groove opening of each tooth groove is 2.0-3.0 mm, the width of the bottom edge is 2.5-2.8 mm, and the length of each side edge is 11-12 mm. The stator lamination for a motor of a wind generator enables the tooth groove size and shape to be reasonable in design, and enables the width of the groove opening of each tooth groove to be increased and the width of each tooth groove to be gradually increased from the bottom edge to the top edges thereby enabling more copper wires to be conveniently embedded.
Description
Technical field
The utility model relates to blower motor, particularly a kind of blower motor stator punching.
Background technology
Slot size, the shape of the winding around that is provided with in the blower fan stator punching at present are reasonable inadequately, and not only operation has brought difficulty to lambda line, but also can cause adverse effect to motor properties.
The utility model content
The utility model has overcome the deficiency that exists in the above-mentioned prior art, provides a kind of slot form, size design reasonable, and can improve the stator punching of motor performance.
The technical scheme of the utility model is achieved in that
A kind of blower motor stator punching, described stator punching integral body is rounded, and described stator punching comprises circular punching body; On the periphery of punching body, be evenly distributed with several in order to twine the teeth groove of stator coil, form tooth portion between teeth groove and the teeth groove, described teeth groove comprises the base; Symmetry is extended with two sides obliquely along the two ends, base, is extended with two top margins of symmetry along the summit of dual-side, forms notch between two top margins; Base, side and top margin are straight line; Angulation is 75 °～85 ° between side and the base, and top margin and base angulation are 10 °～20 °, and the width of rebate of teeth groove is 2.0～3.0mm; The width on base is 2.5～2.8mm, and the length of side is 11～12mm.
As preferably, 24 teeth groove are arranged in the peripheral distribution of punching body.
Adopted the beneficial effect of the utility model of technique scheme to be:
The stator punching of the utility model has passed through the appropriate design to size, shape; Because flute profile size, shaped design are reasonable, increased the width of teeth groove notch, space width is continued to increase to top margin by the base; Can conveniently embed more copper cash, help improving electric efficiency.
