Abstract
The utility model provides a rotor punching sheet, which comprises a rotor punching sheet body. Two groups of winding slots are symmetrically arranged on the round edge of the rotor punching sheet body, separating members are arranged at the positions of the central axes of the winding slots, the separating members enable the winding slots to be divided into right chambers and left chambers, and slot walls of the winding slots are arc edges. Four rotor punching sheet slots are symmetrically arranged on each arc section, each rotor punching sheet slot comprises a notch and a winding portion, the width of each notch is 1mm, the winding portions are in a circular shape, and the diameter of each winding portion is 4.2mm. Only a stamping die of the rotor punching sheet needs to be changed, and an original assembly mode of a generator is not changed. The rotor punching sheet can improve efficiency of the generator, is less in electromagnetic noises, reduces heat radiation of the rotor punching sheet and copper loss, lowers reactive power consumption of the generator, and improves output efficiency of the generator during a long-time use process.
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 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: rotor punching; Comprise the rotor punching body, the round edge symmetry of this rotor punching body has two groups of winding slots, and the place is provided with partition in said winding slot axis; This partition is divided into left and right two chambers with said winding slot, and said winding slot cell wall is the circular arc limit; Be arranged with 4 rotor punching grooves on every arc section, 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, cut off on the vertical line of lines and be arranged with two circular holes with two on this rotor punching body.
When adopting technique scheme, the utility model has the advantages that: said winding slot cell wall is the circular arc limit, is arranged with 4 rotor punching grooves on every arc section, and is cutting off on the vertical line of lines and be arranged with two circular holes with two 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; The utility model rotor punching; Comprise rotor punching body 1, the round edge symmetry of this rotor punching body 1 has two groups of winding slots 2, is provided with at place, said winding slot 2 axis and cuts off 21; This partition 21 is divided into left and right two chambers with said winding slot, cuts off on the vertical line of lines and is arranged with two circular holes 4 with two on this rotor punching body 1.Said winding slot 2 cell walls are the circular arc limit; Be arranged with 4 rotor punching grooves 6 on every arc section, said rotor punching groove 6 comprises notch 61 and winding section 62, and said notch 61 width are 1mm; Said winding section is the circle of diameter 4.2mm.
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.
