Abstract
The utility model relates to a rotor sheet which comprises a rotor sheet body, wherein two groups of winding grooves are symmetrically formed on the round edge of the rotor sheet body, a partition is arranged at the axial line of each winding groove, each winding groove is divided into a left cavity and a right cavity through the winding groove, the groove wall of each winding groove is a circular arc edge, and a semi-circular gap is arranged on the bottom edge of one winding groove. The groove wall of each winding groove is the circular arc edge, the semi-circular gap is arranged on the bottom edge of one winding groove and two circular holes are symmetrically arranged on a line which is vertical to the connection line of the two partitions on the rotor sheet body. Only a stamping mould of the rotor sheet needs to be changed, and the original assembly way of a power generator does not need to be changed; by adopting the rotor sheet, the efficiency of the power generation can be improved, the electromagnetic noise is small and the heat and the copper loss of the rotor sheet are reduced during the long-term using process, the reactive power consumption of the power generator is reduced and the output efficiency of the power generator is improved.
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, comprise the rotor punching body, and 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; 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, and the base of a said winding slot is provided with semicircle breach.
Further, the diameter of said semicircle breach is 0.5mm.
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; And the base of a winding slot therein is provided with semicircle breach, 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; A kind of rotor punching of the utility model comprises rotor punching body 1, and the round edge place symmetry of this rotor punching body 1 has two groups of winding slots 2; Place, axis at said winding slot 2 is provided with partition 21, and this partition 21 is divided into left and right two chambers with said winding slot.The cell wall of said winding slot 2 is the circular arc limit, and the base of one of them winding slot 2 has the semicircle breach 22 that a diameter is 0.5mm.Cut off on the vertical line of 21 lines and also be symmetrical set two circular holes 3 with two on this rotor punching body 1.
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.
