Abstract
The utility model relates to the technical field of motor parts. A connection structure for an end ring and a conducting bar solves the disadvantage that the end ring hinders an inner fan of a motor from radiating heat of a stator and a rotor so as to cause the motor temperature is too high and the motor is easy to be burnt out. The connection structure for the end ring and the conducting bar comprises the end ring and the conducting bar, the conducting bar is a circular ring which is configured and fixedly connected with a motor rotor core, the outer surface of the circular ring of the conducting bar is a combined surface of a circular inclined surface and a circular plane, the end ring is a circular ring which is fixedly connected at an inner side of the circular ring of the conducting bar, a gap exists between the outer surface of the conducting bar and the motor stator, and the end ring and the conducting bar are connected by welding. According to the connection structure for the end ring and the conducting bar, wind sent by the inner fan enters the gap between the rotor and the stator and the rotor core along the inclined surface of the conducting bar, and then flows into radiation channels to be exhausted, so that collective radiation of rotor inner layer and outer layer is realized, and a favorable radiation effect is achieved.
Description
Technical field
The utility model relates to the motor component technical field, relates in particular to a kind of end ring and sliver syndeton.
Background technology
Progress along with science and technology, society's convergence automation gradually, and for automation provides power, motor and engine are arranged, engine noise and vibration are larger, and efficient is lower, generally all is used for moment when not larger, and motor is lightly convenient comparatively speaking, more press close to daily life, equally at mechanical field essential.Yet the some shortcomings of motor will be appeared in one's mind out this moment, and such as the heat dissipation problem of motor, because motor often rotated in 24 hours, therefore heat radiation is maximum test.The patent No. is that the invention of ZL201220044314.8 has proposed " a kind of whirligig that turns end ring and sliver welding for motor ", only be to provide a kind of the device of end ring and sliver welding, do not change the planform of end ring and sliver, as in the past, welding of motor rotor terminal ring is in the sliver end, stopped that cooling air enters air gap, affected the cooling effect of stator rotor iron core.
The utility model content
The purpose of this utility model is: for the deficiencies in the prior art, propose a kind of end ring and sliver Welding Structure, overcome end ring and hindered the heat radiation of internal fan for electric machine to stator and rotor core, cause motor temperature too high, the shortcoming that easily burns out.
The technical solution adopted in the utility model:
A kind of end ring and sliver syndeton, comprise end ring and sliver, the annulus of described sliver for being fixedly connected with the motor rotor core coupling, sliver annulus outer surface is the combinatorial surface that circular inclined plane and circular flat consist of, described end ring is annulus, is fixedly connected at the sliver annulus inboard.
Gapped between the outer surface of described sliver and motor stator.
Described end ring and sliver welding.
Useful good effect of the present utility model:
the shape of the sliver that the utility model changes, be close to be fixedly connected on motor rotor core with sliver annulus in the past and compare, sliver obviously increases, the sliver outer surface changes the composite surface of inclined plane and plane formation into, yet the size of end ring reduces, and change the annulus inboard with the link position of sliver into by original end, make like this wind that blown by internal fan to enter in the gap of rotor and stator and rotor core along the sliver inclined plane, then flowing to heat dissipation channel discharges, realized the heat radiation of rotor ectonexine collective, particularly rotor core has reached good radiating effect.
Description of drawings
Fig. 1 is the structural representation of end ring and sliver;
Fig. 2 is the zoomed-in view in Fig. 1 circle.
Embodiment
Referring to Fig. 1～2,1. motor plate, 2. stator, 3. heat dissipation channel, 4. rotor core, 5. end ring, 6. sliver, 7. internal fan.
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
referring to Fig. 1～Fig. 2, a kind of end ring 5 and sliver 6 syndetons, comprise end ring 5 and sliver 6, the annulus of described sliver 6 for being fixedly connected with motor rotor core 4 couplings, between the outer surface of sliver 6 and motor stator 2, gapped sliver 6 annulus outer surfaces are the combinatorial surface that circular inclined plane and circular flat consist of, make like this sliver and motor stator shape at an angle, and area of dissipation increases, facilitate the wind of internal fan 7 to enter the gap of sliver 6 and stator 2, then discharged by heat dissipation channel 3, reach the purpose of rotor outer surface heat radiation, described end ring is similarly annular, be connected with sliver 6 annulus are inboard by welding, so just can not stop that wind enters the gap of sliver 6 and stator 2.
Claims (3)
1. an end ring and sliver syndeton, comprise end ring and sliver, it is characterized in that: the annulus of described sliver for being fixedly connected with the motor rotor core coupling, sliver annulus outer surface is the combinatorial surface that circular inclined plane and circular flat consist of, described end ring is annulus, is fixedly connected at the sliver annulus inboard.
