Abstract

The invention relates to a stepping motor vibration reduction rotor. The stepping motor vibration reduction rotor comprises a rotor shaft, a front outer side rotor core, a rear outer side rotor core, a front inner side rotor core, a rear inner side rotor core, front side rotor core magnetic steel, rear side rotor core magnetic steel and a circular ring elastic body assembly; the rotor shaft sequentially penetrates through the front outer side rotor core, the front inner side rotor core, the circular ring elastic body assembly, the rear inner side rotor core and the rear outer side rotor core; the front outer side rotor core and the front inner side rotor core form a front rotor core set, and the front side rotor core magnetic steel is arranged in a groove of the front rotor core set; and the rear outer side rotor core and the rear inner side rotor core form a rear rotor iron core set, and the rear side rotor core magnetic steel is arranged in a groove of the rear rotor core set. Compared with the prior art, the rotor can reduce the vibration of the motor and improve the running stability of the motor.

Description

Technical field [0001] The present invention relates to a stepping motor, particularly to a stepping motor rotor vibration. Background technique [0002] like Figure 1-5 , The conventional stepping motor rotor assembly, is composed of the conventional front and rear rotor core 3, the conventional magnet between two rotor cores 4 and the conventional motor shaft 2, the conventional front and rear rotor core 3 radially deflects a certain angle, the material 4 is generally conventional magnet NdFeB NdFeB. [0003] Stepper motor is running, the presence of the above-described conventional motor rotor radial and axial vibrations, poor motor running smoothly. Inventive content [0004] The object of the present invention is to solve the problems of the prior art described above and to provide a stepping motor rotor vibration. [0005] The object of the present invention can be achieved by the following technical solutions: [0006] According to one aspect of the present invention, the...
