Abstract
The utility model discloses a novel punching sheet for a rotor, which comprises a punching sheet body. Two winding slots are axially and symmetrically arranged on the punching sheet body; the walls of the winding slots are provided with edges shaped like circular arcs; the bottom edge of the one of the winding slots is provided with a semicircular notch; the symmetrical axis of the winding slots is provided with two round holes; two circular-arc shaped sections of the punching sheet body are respectively provided with four punching sheet slots; and each punching sheet slot comprises an opening and a wire winding part, wherein the opening has a width of 1 mm, and the wire winding part is round in shape and has a diameter of 4.2 mm. Only the punching mold of the punching sheet for the rotor needs to be changed, and the original assembling mode of a power generator does not need to be changed. The punching sheet for the rotor improves the output efficiency of the power generator, produces low electromagnetic noise and less heat and consumes less copper in the long-term use process and reduces the reactive energy consumption.
Description
Technical field
The utility model belongs to technical field of motors, specifically, relates to a kind of generator amature punching.
Background technology
The rotor punching of generator generally adopts silicon steel sheet to process; Be provided with outline and be circular punching body; The round edge symmetry of this punching body has two groups of winding slots, cuts off outstanding formation of the bottom land at place, said winding slot axis, and this partition is divided into two chambers with said winding slot; The height of said partition is lower than the height of winding slot cell wall; Cutting off width is 1/4～1/5 of said winding slot Breadth Maximum, on the axis that cuts off, has mounting groove, and the notch of this mounting groove is positioned at and cuts off the top., some rotor punchings just form generator amature after being stacked; Just can in winding slot, twine motor windings, the cover cartridge screw is fixed on winding in the winding slot by gland with stationary gland on the mounting groove; Simultaneously; Be to guarantee the winding number of turns of winding in the winding slot, need to strengthen the space of winding slot, prior art comprises that the inwall to winding slot digs and cuts; Make the body width at winding slot cell wall root place locate 2～3 times of the body width, even sacrifice the width of rotor punching main body for the cell wall top.Rotor punching is the key components and parts in the generator, its material, interior round size, excircle dimension, flute profile size, flute profile what etc. the efficient of generator is had direct influence.
The utility model content
The purpose of the utility model is to provide a kind of novel rotor punching, and this rotor punching is used for generator, and in long-term use, electromagnetic noise is little, rotor punching generates heat and copper loss reduces, and reduces the idle energy consumption of generator, improves the delivery efficiency of generator.
For achieving the above object; The technical scheme of the utility model is a kind of novel rotor punching, comprises the rotor punching body, and axial symmetry is provided with 2 winding slots on the said rotor punching body; Said winding slot cell wall is the circular arc limit; The base of one of them winding slot is provided with semicircle breach, and the axis of symmetry of said winding slot is provided with two circular holes, is respectively equipped with 4 rotor punching grooves on two sections arc sections on the said rotor punching body; Said rotor punching groove comprises notch and winding section, and said width of rebate is 1mm; Said winding section is circular, and diameter is 4.2mm.
Further, the diameter of said breach is 0.5mm.
Further, the angle of circle center line connecting is 10 ° in said adjacent two the rotor punching grooves, the center of circle of its winding section and rotor punching.
When adopting technique scheme; The utility model has the advantages that: axial symmetry is provided with 2 winding slots on the said rotor punching body; Said winding slot cell wall is the circular arc limit; The base of one of them winding slot is provided with semicircle breach, and the axis of symmetry of said winding slot is provided with two circular holes, is respectively equipped with 4 rotor punching grooves on two sections arc sections on the rotor punching body.Only need to change the diel of rotor punching, do not change original fit of generator; This rotor punching can improve the efficient of generator, and in long-term use, electromagnetic noise is little, rotor punching generates heat and copper loss reduces, and reduces the idle energy consumption of generator, improves the delivery efficiency of generator.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model rotor punching embodiment.
Embodiment
As shown in Figure 1; A kind of novel rotor punching of the utility model comprises rotor punching body 1, and axial symmetry is provided with 2 winding slots 2 on the said rotor punching body 1; Said winding slot 2 cell walls are the circular arc limit; It is the semicircle breach 5 of 0.5mm that the base of one of them winding slot 2 is provided with diameter, and the axis of symmetry of said winding slot 2 is provided with two circular holes 4, is respectively equipped with 4 rotor punching grooves 6 on two sections arc sections on the said rotor punching body 1; Said rotor punching groove 6 comprises notch 61 and winding section 62, and said notch 61 width are 1mm; Said winding section 62 is that diameter is the circle of 4.2mm.Adjacent two rotor punching grooves, in the center of circle of its winding section and the rotor punching angle a=10 ° of circle center line connecting.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection range of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
