Specific embodiment
In order to preferably illustrate the present invention, it is described in detail with reference to the accompanying drawing.
As Figure 1-10 shows, a kind of band eccentric gear brushless motor, including circle stator core 1, rotor 2, machine shaft 3,
It is equipped with rotor in the round stator core, further includes eccentric speed reduction gear-box 4, the rotor is encapsulated by machine shaft 3, rotor
22, ferrite bead 21 is constituted, and 3 outer sheath of machine shaft switches through attached bag glue 22, and encapsulated 22 outside of rotor is connected with
Ferrite bead 21, the machine shaft 3 are connected with eccentric speed reduction gear-box 4, and the eccentric speed reduction gear-box is set with deceleration
Than for 32:1.
Preferably, the round stator core 1 is welded by bending to circular vertical bar stator core both ends, vertical bar stator
Encapsulated layer 11 and winding structure are equipped on the outside of iron core, vertical bar stator core is arranged by the punching of stator height.The round stator iron
Core uses 12 slot type structures, and width of rebate 2.2-3.2mm, the round stator core internal diameter is Φ 55-60mm, outer diameter is
