Abstract
The invention discloses a shaded pole motor integrated punching sheet which is of a rectangle shape integrally. The integrated punching sheet comprises four pole pieces and four magnetic steel holes. The pole pieces are disposed in an integrated structure along the periphery of a motor axle hole. One of the magnetic steel holes is arranged between each two adjacent pole pieces and each magnetic steel hole is in an oval shape. Magnetic steel grooves are respectively arranged at two ends of each magnetic steel hole along the radius direction of the motor axle hole. Each of the magnetic steel grooves close to the motor axle hole is communicated with the motor axle hole. The length of the long side of the punching sheet is 81 to 83 mm. The length of the short side of the punching sheet is 74 to 76 mm. The length of the long axis of the magnetic steel hole is 35 to 38 mm. The length of the long axis of the magnetic steel hole is 35 to 38 mm. The length of the short axis of the magnetic steel hole is 15 to 18 mm. The diameter of the motor axle hole is 43 to 46 mm. By adopting the technical scheme, the shaded pole motor integrated punching sheet adopts an integrated structure, so that an imbalance phenomenon, caused by an assembly error of a plurality of original independent magnetic poles, of a rotor is eliminated. The problem of the uneven widths of original magnetic steel grooves is resolved and the assembly efficiency of magnetic steels is improved.
Description
Technical field
The present invention relates to technical field of motors, particularly a kind of shading-pole electric motor rotor disjunctor punching.
Background technology
The shading-pole electric motor rotor structure is the number of poles quantity according to motor at present, form around the shaft circumference distribution by the separate magnetic pole that equates with number of magnetic poles, each independently magnetic pole make after laminating by some pole laminations, each separate magnetic pole is separated by certain gap around machine shaft, be bolted on magnetic shield, in magnetic pole, penetrate some copper bars and the two ends end ring is welded to form rotor; The randomness that can cause like this magnetic pole to distribute strengthens, and accumulated error increases, and magnetic pole is not exclusively even in the machine shaft radial distribution, has caused the problems such as alinco assembled difficulty.
Moreover present punching size design is unreasonable, thereby is unfavorable for the motor energy efficient, also is unfavorable for reducing cost.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of alinco assembled convenient, size, structure, groove design are reasonable, can reduce rotor unbalance degree, and improve the integration stamped sheet of electric efficiency and energy-saving effect.
Technical scheme of the present invention is achieved in that
The punching of a kind of motor with cup rotor disjunctor, described punching integral body is rectangle, it comprises 4 pole pieces, 4 magnet steel holes, described pole piece is set to integral structure along the motor axis hole circumference, be provided with a magnet steel hole between every two adjacent pole pieces, described magnet steel hole is oval, is respectively equipped with the magnet steel groove at the two ends along the magnet steel hole of motor axis hole radial direction, is connected with motor axis hole near the magnet steel groove at motor axis hole center; The long edge lengths of punching is 81～83mm, and the bond length of punching is 74～76mm, and the major axis length in magnet steel hole is 35～38mm, and the minor axis length in magnet steel hole is 15～18mm, and the diameter of motor axis hole is 43～46mm.
As preferably, on pole piece, also be provided with ventilation hole.
Adopted the present invention of technique scheme to adopt integral structure, eliminated the rigging error of original a plurality of independent magnetic poles and the rotor unbalance phenomenon that causes, the problem of having eliminated the narrow inequality of magnet steel groove width has improved alinco assembled efficient.
Moreover the present invention has made appropriate design to size, the slotted shape size of punching, make load on call magnet steel after, Distribution of Magnetic Field is more even, is conducive to improve electric efficiency, thereby improves energy-saving effect.
Description of drawings
Fig. 1 is structural representation of the present invention.
