Description
Technical field
The utility model 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.
The utility model content
The utility model is for above-mentioned the deficiencies in the prior art, provides a kind of alinco assembled convenient, and size, structure, groove design are reasonable, can reduce rotor unbalance degree, and improve the integration stamped sheet of electric efficiency and energy-saving effect.
The technical solution of the utility model 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 utility model 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 utility model has been 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 utility model.
