Abstract
The utility model discloses a high -efficient ventilation cooling's motor rotor punching sheet, the outside and the material of this rotor punching are the same towards the piece with the conventionality, and it has the ventilation hole to open in the inboard towards the piece, leaves and supports step and location step. The ventilation hole is as the ventilation passageway, support the step and support the rotor punching to the enhancement keeps towards the regularity of piece pressure equipment towards the inboard intensity of piece simultaneously, location step is used for fixing towards the piece, injects towards the degree of freedom of piece, prevents towards the rotation of piece. Whole towards the direct pressure equipment of piece on motor shaft. The utility model has the beneficial effects of: (1 ) ventilation cooling is good, (2 ) light in weight, (3 )Installation convenient operation.
Description
Technical field
This utility model relates to a kind of motor rotor punching sheet.
Background technology
The rotor of motor is mainly armature and provides magnetic field, and rotor is wound with coil.When motor runs, producing armature-reaction, cause rotor coil, punching heating, this is accomplished by timely heat being discharged motor, by the temperature rise control of motor within the specific limits.The heat dissipation conductor of general motor is natural wind, utilizes fan to be sucked from motor rear end by natural wind, by armature, with natural wind as carrier, is discharged from front end by the heat produced.But, between general rotor and stator, air gap is the least, a large amount of coil of coiling in winding slot, and vent passages is greatly reduced, and motor internal ventilation is extremely limited, have impact on the temperature rise index of motor.Accordingly, it would be desirable to develop the motor rotor punching sheet of a kind of high-efficient ventilation heat radiation, improve vent passages, improve temperature rise index.
Summary of the invention
The purpose of this utility model is the motor rotor punching sheet providing a kind of high-efficient ventilation to dispel the heat, and this lamination structure is simple, processing, easy for installation, and lightweight, ventilation and heat is good.
This utility model is achieved in that the motor rotor punching sheet that a kind of high-efficient ventilation dispels the heat, it is characterised in that: have air vent inside described rotor punching, leave support level and positioning step.Air vent is as vent passages；Support level supports rotor punching, and strengthens intensity inside punching, keeps the regularity that punching press-fits simultaneously；Positioning step is used for fixing punching, limits the degree of freedom of punching, prevents the rotation of punching.
Outside described punching and conventional punching is basically identical, have winding slot, damping hole, rivet hole as required.With conventional amortisseur bar and rivet, punching being press-fited reinforcing is an entirety.
Operation principle of the present utility model is: after punching laminates as iron core, and the inner side air vent of punching forms vent passages with machine shaft, and natural cooling wind passes through from air channel, takes away iron core and the heat of coil generation, limits motor temperature rise；The support level inner side edge of punching forms supporting surface, closely cooperates with machine shaft, it is ensured that the degree of accuracy of iron core pressure mounting and regularity, and support level plays simultaneously strengthens the effect of intensity inside punching；Punching positioning step forms positioning key, replaces the flat key of conventional motors, is positioned directly in the keyway of machine shaft.
Of the present utility model have the technical effect that in the case of not affecting motor performance, increase motor internal vent passages, increase the natural cooling wind throughput at motor internal, reduce motor temperature rise.The offering of air vent simultaneously, decreases the weight of punching, thus alleviates the weight of motor.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Fig. 2 is utilization embodiment of the present utility model.
In the drawings: 1, damping hole, 2, winding slot, 3, rivet hole, 4, positioning step, 5, support level, 6, air vent, 7, armature coil, 8, machine shaft.
Detailed description of the invention
Illustrate embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing, but the present embodiment is not limited to this utility model, every employing analog structure of the present utility model and similar change thereof, all should list protection domain of the present utility model in.
As Figure 1-Figure 2, this utility model is such to enforcement, punching according to different motors need offer different winding slots 2 and damping hole 1, winding slot 2 outside punching is for coiling armature coil 7, and the damping hole 1 at punching outer is for field riveting amortisseur bar, and interpolar has rivet hole 3, for installing rivet, when punching press-fits for iron core, compress punching by amortisseur bar and rivet hole 3, make firm entirety.Inside punching, have air vent 6, punching press-fits for iron core on machine shaft 8, and air vent 6 and machine shaft 8 form vent passages, as the path of natural cooling wind, leave support level 5 and positioning step 4, when punching press-fits into iron core, support level 5 inner side edge forms supporting surface, closely cooperates with machine shaft 8, ensure degree of accuracy and the regularity of iron core pressure mounting, play simultaneously and strengthen the effect of intensity inside punching.Punching positioning step 4 forms positioning key, replaces the flat key of conventional motors, is positioned directly in the keyway of machine shaft 8, fixing whole iron core, it is to avoid rotation unshakable in one's determination.
Claims (2)
1. the motor rotor punching sheet of a high-efficient ventilation heat radiation, it is characterised in that: have air vent inside described rotor punching, leave support level and positioning step.
The motor rotor punching sheet of high-efficient ventilation the most according to claim 1 heat radiation, it is characterised in that: have winding slot, damping hole, rivet hole outside described rotor punching.
