Description
Technical field
The utility model relates to technical field of generators, is specifically related to a kind of single-phase electric machine stator lamination.
Background technology
At present in technical field of generators, conventional single-phase electric machine stator lamination material is mainly silicon steel sheet, its structure mainly comprises punching body, winding slot on punching body by the direct punch forming of drift, the outline of punching body is commonly circular, and punching body medium position place is provided with circular hole, winding slot is uniform to be arranged on along in the circumferential edge of circular hole, and general quantity is 30 ~ 40.
Utility model content
The utility model aims to provide and a kind of effectively improves silicon steel sheet utilance, reduces copper loss, the single-phase electric machine stator lamination of easy to operate during installation, registration.
For this reason, the technical scheme that the utility model adopts is: a kind of single-phase electric machine stator lamination, comprise punching body, described punching body is rectangle, connected by arc section between limit adjacent between two arbitrarily, article four, arc section is positioned at circumferentially same, and the center of circumference and rectangular center superposition, every bar limit arranges two symmetrical grooves, semicircular solder joint is had in the middle of each groove, and the distance that the distance between two solder joints on long limit is greater than on minor face between two solder joints, the top of described solder joint flushes with the limit of punching body, four angle position places of described punching body are respectively provided with a bolt through-hole, the middle part of described punching body is provided with circular hole, circumferential edge along circular hole is provided with two groups of winding slots, two groups of winding slots separated time bilateral symmetry in punching body two minor face is arranged.
Further, described semicircular solder joint root is connected with the rectangular limit at place by straightway, oblique line section successively, described straightway is parallel with the rectangular limit at place, between described semicircle and straightway, between straightway and oblique line section, the rectangular limit at oblique line section and place is respectively by arc transition.Optimize the recessed groove structure at solder joint place, be convenient to the design of diel.
The area of each winding slot is 52mm
2, the area of winding slot should be area matched with the copper cash be wound around, and winding slot area is excessive, then waste copper cash; Winding slot area is too small, is not suitable for batch machining.
The beneficial effects of the utility model: this stator laminating structure is simple, make traditional circular configuration into rectangle structure, decrease process residue, improve the utilance of silicon steel sheet, reduce copper loss, under same power section, the silicon steel sheet utilance of 13% can be improved compared to the stator of 160 three generations's flap-type, reduce copper loss 10%; Secondly, winding slot divides two groups, along circular hole circumferential edge but be not paved with the circumferential edge of whole circular hole, further reduce process residue, improve the utilance of silicon steel sheet, and then reduce copper loss; Respectively arrange a bolt through-hole at four angle position places of punching body, all stator punching bodies are bolted installation, install more reliable; Set up solder joint, convenient when making installation, reduce waste material, it is more accurate to install location.
