Abstract
The utility model relates to a rotor lamination, comprising a rotor lamination body, wherein the round edge of the rotor lamination body is symmetrically provided with two groups of coil slots, at the position of the central axis of the coil slot there is provided a separator dividing the coil slot into left and right cavities, the slot wall of the coil slot is provided with an arc edge, the bottom edge of the coil slot is provided with a semicircular gap, and two arc segments of the rotor lamination body are provided with two notches in a manner of axial symmetry. The rotor lamination only enables the stamping die of the rotor lamination to be changed, and does not change the original assembling mode of the generator; and the rotor lamination can enable the efficiency of generator to be increased, the electromagnetic noise to be decreased, the heat generation and the copper consumption of the rotor lamination to be reduced, the wattless energy consumption of the generator to be reduced and the output efficiency of the generator to be increased, in the long term using 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 a kind of 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 rotor punching comprises the rotor punching body; The round edge symmetry of this rotor punching body has two groups of winding slots; The place is provided with partition in said winding slot axis, and 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; The base of a said winding slot is provided with semicircle breach, and axial symmetry is provided with 2 notches on two sections arc sections on the said rotor punching body.
Further, the diameter of said semicircle breach is 0.5mm.
Further, the line of symmetry through said two notches is provided with two circular holes.
When adopting technique scheme, the utility model has the advantages that: said winding slot cell wall is the circular arc limit, and the base of a said winding slot is provided with semicircle breach, and axial symmetry is provided with 2 notches on two sections arc sections on the said 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 rotor punching of the utility model comprises rotor punching body 1; The round edge symmetry of this rotor punching body 1 has two groups of winding slots 2; The place is provided with partition 21 in said winding slot 2 axis, and this partition 21 is divided into left and right two chambers with said winding slot, and said winding slot 2 cell walls are the circular arc limit; The base of a said winding slot 2 is provided with the semicircle breach 22 that diameter is 0.5mm, and axial symmetry is provided with 2 notches 3 on two sections arc sections on the said rotor punching body.Line of symmetry through said two notches 3 is provided with two circular holes 4.
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.
