Description

A kind of rotor
Technical field
The present invention is a kind of rotor, particularly a kind of rotor of family expenses fan monophase ac capacitance motor.
Background technology
The rotor of traditional fan monophase ac capacitance motor, a kind of is that cast aluminium end ring direct casting at the rotor core two ends that are the mouse cage shape goes out blade, rotor banding moving vane agitation air is given motor radiating during the motor operation; The heat abstractor of this structure, problem such as blade is yielding when having transportation.A kind of in addition is to adopt the band blade shaft to be locked to be enclosed within the two ends of rotor that is the mouse cage shape, and axle sleeve contacts with rotor surface like this, and its area of dissipation reduces, and the through-flow wind radiating effect that is produced is limited.Above traditional motor radiating mode has all increased the cost of motor, and the increase of material simultaneously adds the inertia of greater trochanter, and starting effect is poor.
Summary of the invention
The objective of the invention is to consider above-mentioned and a kind of not only good heat dissipation effect is provided, can effectively reduce motor cost, and can promote the rotor of electric motor starting performance.
Technical scheme of the present invention is: a kind of rotor; Comprise armature spindle and be the rotor of mouse cage shape; Wherein said rotor tightly is enclosed within on the armature spindle, and rotor comprises to be annotated the aluminium end ring and be installed in the rotor core of annotating in the aluminium end ring, and said rotor core is laminated by some rotor punching and forms; On rotor punching, have several equally distributed rotor punching grooves; The rotor core groove is formed by the stack of several rotor punching grooves, and notes aluminium end ring fuses through the aluminium that is filled in the aluminium in the rotor core groove and is distributed in the rotor core end, it is characterized in that on said rotor punching, having several equally distributed through holes; Said through hole is distributed between the minimum diameter of interior circle of rotor punching and rotor punching groove, and the rotor through hole is formed by several through holes stacks.
Said rotor core groove is an inclined hole, and said rotor through hole also is an inclined via-hole.
The quantity of said rotor through hole is evenly distributed in eight.
The angle of inclination of the angle of inclination of said rotor core groove and rotor through hole is consistent.
The present invention's advantage compared with prior art is: owing on rotor core, open some inclined via-holes, increase area of dissipation, during motor rotation; Inclined via-hole self forms blast; Produce axial flow wind, the heat that well motor is produced is by axially conducting the blast that inclined via-hole self produces; Consistent with the blast axial direction that motor load produces, radiating effect is better.In addition, open inclined via-hole on the rotor core, the unnecessary iron that in the rotor core performance is not had an influence is saved, reduce rotor weight, help promoting the electric motor starting performance, raw-material minimizing has also reduced motor cost, and is easy to make.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail.
Shown in Fig. 1 to 5; A kind of rotor; Comprise armature spindle 1 and be the rotor 2 of mouse cage shape; Wherein said rotor 2 tightly is enclosed within on the armature spindle 1, and rotor 2 comprises to be annotated aluminium end ring 22 and be installed in the rotor core of annotating in the aluminium end ring 22 21, and said rotor core 21 is laminated by some rotor punching 211 and forms; On rotor punching 211, have several rotor punching grooves 2111; Some rotor punchings 211 are overlapped together the back form rotor core groove 212, rotor core groove 212 runs through rotor core 21, annotates aluminium end ring 22 and fuses through the aluminium that is filled in the aluminium in the rotor core groove 212 and is distributed in rotor core 21 ends; Characteristics of the present invention are on said rotor punching 211, to have several equally distributed through holes 2112; Said through hole 2112 is distributed between the minimum diameter 2114 of interior circle 2113 of rotor punching and rotor punching groove 2111, some rotor punchings 211 is overlapped together the back form the stack formation that rotor through hole 213 is each through hole 2112, and rotor through hole 213 runs through rotor core 21.In order to ensure the torsion that rotor core 21 and armature spindle 1 tightly are nested together, through hole 2112 will have enough spaces with the interior circle 2113 of rotor punching, and its space size requires to increase and decrease with torque magnitude.Simultaneously, from motor performance, also enough spaces will be arranged between the minimum diameter of through hole 2112 and rotor punching groove 2111, to guarantee the close reasonable levels that reaches of rotor yoke magnetic, radial width is between the two generally got about 0.5 times of rotor tooth portion width.Through hole 2112 evenly distributes, and dynamic balancing is secure during the high rotating speed of rotor like this, can when the punching out rotor punching, through hole be rushed out in the lump, does not increase production process, and is easy to make.
After said rotor punching 211 laminated into rotor core 21, said rotor core groove 212 was an inclined hole, and said rotor through hole 213 also is an inclined via-hole.The quantity of said through hole 2112 is evenly distributed in eight, so the quantity of rotor through hole 213 is also in eight; In the present embodiment, three rotor through holes 213 are arranged, rotor through holes 213 such as four or five also can be set according to actual needs.Be convenient processing, the one punching out when punching out rotor punching 211 of the rotor through hole 213 of said rotor core 21 is come out, and rotor core 21 rivetings to armature spindle 1, are accomplished rotor.
In the present embodiment, during motor rotation, rotor through hole 213 rotates and self can form blast, produces axial flow wind, with the past axial diffusion of the heat of motor generation.The angle of inclination of the angle of inclination of said rotor core groove 212 and rotor through hole 213 is consistent.During production, during with the rotor punching riveting, make the angle of inclination of rotor core groove 212 and rotor through hole 213 angles consistent.The blast that rotor through hole 213 self produces is consistent with the blast axial direction that motor load produces, and helps heat radiation.
