Abstract
The utility model provides a novel rotor sheet, which comprises a rotor sheet body. Two winding slots are arranged on the rotor sheet body in axial symmetry mode, slot walls of winding slots are arc edges, and two main notches are arranged on two sections of arc sections of the rotor sheet body in axial symmetry mode. Four rotor sheet slots are symmetrically arranged on two sides of each main notch, each rotor 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 sheet needs to be changed, and an original assembly mode of a generator is not changed. The rotor sheet can improve efficiency of the generator, is less in electromagnetic noises, reduces heat radiation of the rotor sheet and copper loss, lowers reactive power consumption of the generator, and improves output efficiency of the generator in 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 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; Axial symmetry is provided with 2 winding slots on the said rotor punching body; Said winding slot cell wall is the circular arc limit, and axial symmetry is provided with 2 major trough mouths on two sections arc sections on the said rotor punching body, and the bilateral symmetry of each major trough mouth is provided with 4 rotor punching grooves; 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 line of symmetry through said two major trough mouths is provided with two circular holes.
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.
Further, the base of a said winding slot is provided with semicircle breach.
Further, the diameter of said breach is 0.5mm.
When adopting technique scheme; The utility model has the advantages that: axial symmetry is provided with 2 major trough mouths on two sections arc sections stating on the rotor punching body; The bilateral symmetry of each major trough mouth is provided with 4 rotor punching grooves; Line of symmetry through said two major trough mouths is provided with two circular holes, and the base of a said winding slot is provided with semicircle breach, and the base of a said winding slot is provided with semicircle breach.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;
Fig. 2 is the partial enlarged drawing of Fig. 1.
