There are some grooves.
In a kind of aforesaid washing machine motor rotor with mute function, described internal rotor and outer rotor left and right sides table
The middle part in face is provided with the mounting groove of ring-type, and mounting groove is provided with PBT connecting seat；The PBT connecting seat of adjacent two pieces of permanent magnets is solid
Surely it is connected on the outer surface of outer rotor.
In a kind of aforesaid washing machine motor rotor with mute function, described rubber shock-absorbing layer inner and outer surfaces recessed
Groove is connected with male part and interior protuberance respectively, and the length of male part and interior protuberance is respectively less than the thickness of rubber shock-absorbing layer.
Compared with prior art, present invention improves over the structure of rotor, by arranging interior protuberance, male part and recessed
Groove, increased the contact area between rubber shock-absorbing layer and outer rotor and internal rotor, strengthens rubber shock-absorbing layer, outer rotor and interior turn
Connection between son.Meanwhile, the present invention is also provided with PBT connecting seat, the PBT connecting seat on outer rotor outer surface can strengthen and
Guarantee the connection between permanent magnet and outer rotor；PBT connecting seat on outer rotor and internal rotor both side surface can not only limit
The axial location of rubber shock-absorbing layer, can also strengthen overall construction intensity it is ensured that the concentricity of internal rotor and outer rotor is at one
In stable normal range (NR).And, it is provided with some suction holes in the rubber shock-absorbing layer of the present invention, by rubber shock-absorbing layer
Moreover it is possible to noise is absorbed by suction hole while damping noise reduction, substantially increase muting function.Therefore, the present invention can not only
Prevent rubber shock-absorbing layer from coming off it is ensured that motor normal work, also have the advantages that good damping effect and muting function are good.
