Abstract
The utility model discloses an integrated punching sheet, comprising magnetic pole sheets and magnetic steel holes, wherein the magnetic pole sheets are arranged to be an integrated structure along motor shaft-hole circumference. One magnetic steel hole is mounted between every two adjacent magnetic pole sheets and is elliptic. Magnetic steel grooves are respectively mounted on two ends of the magnetic steel hole along a radius direction of the motor shaft hole. The magnetic steel groove close to a center of the motor shaft hole is communicated with the motor shaft hole. The integrated punching sheet provided by the utility model adopting the above technology scheme adopts the integrated structure, a rotor imbalance phenomenon caused by assembling errors of a plurality of conventional independent magnetic poles is eliminated, a problem of the uneven width magnetic steel grooves is eliminated and magnetic-steel assembling efficiency is raised.
Description
Technical field
The utility model relates to technical field of motors, particularly a kind of shading-pole electric motor rotor integration stamped sheet.
Background technology
The shading-pole electric motor rotor structure is the number of poles quantity according to motor at present, distribute around shaft circumference by the separate magnetic pole that equates with number of magnetic poles and form, 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, penetrate some copper bars and the two ends end ring is welded to form rotor in magnetic pole; Can cause like this randomness that magnetic pole distributes to strengthen, 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.
The utility model content
The utility model provides a kind of alinco assembled convenient for above-mentioned the deficiencies in the prior art, can reduce the integration stamped sheet of rotor unbalance degree.
The technical solution of the utility model is achieved in that
Integration stamped sheet, comprise pole piece, magnet steel hole, 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, be respectively equipped with the magnet steel groove at the two ends along the magnet steel hole of motor axis hole radial direction, be connected with motor axis hole near the magnet steel groove at motor axis hole center.
As preferably, also be provided with ventilation hole on pole piece.
As preferably, described punching integral body is square, and it comprises 4 pole pieces and 4 magnet steel holes.
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.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is as follows:
Embodiment: integration stamped sheet, as shown in Figure 1, described punching integral body is square, it comprises 4 pole pieces 1,4 magnet steel holes 2, described pole piece 1 is set to integral structure along motor axis hole 3 circumference, is provided with a magnet steel hole 2 between every two adjacent pole pieces 1, and described magnet steel hole 2 be ellipse, be respectively equipped with magnet steel groove 4 at the two ends along the magnet steel hole 2 of motor axis hole 3 radial directions, be connected with motor axis hole 3 near the magnet steel groove 4 at motor axis hole 3 centers.Also be provided with ventilation hole 5 on pole piece 1.
