[embodiment]
Be illustrated in figure 1 as the structural representation of the utility model galvanometer motor, the utility model relates to a kind of moving-magnetic type galvanometer motor 100 that can be applied in laser labelling, optical scanner or the similar system, and it comprises: fixed stator 2 and relative stator 2 rotor rotated 3.
Consult Fig. 2 to Fig. 4 simultaneously, stator 2 comprises coil 21, shell 22 and yoke 23, and wherein, shell 22 is made of non-magnet material; Be installed on the inwall (or yoke 23 fluting, coil 21 embeds yokes 23) of yoke 23 behind the coil 21 whole encapsulatings, and after coil 21 was positioned at yoke 23, the end face of one end was concordant with the end face of yoke 23, the contact-making surface usefulness glue of itself and yoke 23 is fastening.
Consult Fig. 5 to Fig. 7 simultaneously, yoke 23 is made by silicon steel sheet, its outer face is for being columnar structured (can certainly be square etc. structure), and columnar structured (as Fig. 5) that yoke 23 axially is overrided to form by the disc silicon steel sheet, or fan-shaped silicon steel sheet columnar structured (as Fig. 6) of axially being overrided to form, columnar structured (as Fig. 7) that C type silicon steel sheet axially is overrided to form, the stator 2 that silicon steel sheet makes this galvanometer motor 100 is made the yoke of utilizing silicon steel sheet axially to laminate to be assembled into 23 by high performance permeability magnetic material, have high performance magnetic conductivity and less magnetic hysteresis loss, can significantly improve the response speed of motor.
Consult Fig. 8 and Fig. 9 simultaneously, rotor 3 comprises that producing the action of a magnetic fields with yoke 23 gets columniform bar magnet 31, clutch shaft bearing 32, second bearing 33, fixedly clutch shaft bearing axle 34, second bearing shaft 35 of fixing second bearing 33 and the ripple spring 36 (as Figure 12) of clutch shaft bearing 32, wherein, bar magnet 31 is fixed between the clutch shaft bearing 32 and second bearing 33, and clutch shaft bearing axle 34, second bearing shaft 35 are connected fastening with bar magnet 31 usefulness glue.Bearing Installation is on the clutch shaft bearing axle 11 and second bearing shaft 12, and ripple spring 36 is loaded between two bearings 32,33, to form constant preload.
Wherein, bar magnet 31 is made by the rare earth permanent-magnetic material with high energy product, high remanent magnetism, and bar magnet 31 is a cylindrical exterior, at its magnetizing direction is radial magnetizing, number of poles is the even number utmost point, the bar magnet 31 of rotor 3 combines with the yoke 23 that high performance permeability magnetic material is made like this, makes this motor 100 have high performance index, and its response speed significantly improves.
