Abstract

The utility model discloses a kind of magnetic pole segmentation permanent magnetic servo motor rotor, comprise rotor core, magnet steel, end plate, rivet and rotating shaft; Bonding magnetic steel is on rotor core; Rotor core is divided into two sections, left and right, left section of rotor core and right-hand member rotor core Opposite direction connection; Two iron leg cores and end plate are riveted together by rivet, are assembled into one with magnet steel, rotating shaft, realize magnetic pole segmentation and offset certain angle at circumferencial direction, thus weaken the cogging torque of motor with this; For the micro-machine dividing two sections, adopt the rotor of this kind of method, structure is simple, is easy to realize small lot, enhances product performance, and reduces manufacturing cost.

Description

A kind of magnetic pole segmentation permanent magnetic servo motor rotor
Technical field
The utility model relates to a kind of permanent magnetic servo motor rotor, is specially magnetic pole segment permanent magnet rotor.
Background technology
At present, in order to reduce the slot effect of permanent-magnet servo motor, improve motor low cruise stationarity, the method adopting skewed stator slot or skewed-rotor, although this kind of method is satisfactory for result, processed complex, technology difficulty is large more.In order to Simplified flowsheet, the method for magnetic pole segmentation can be adopted to weaken cogging torque, every pole permanent magnet is divided into isometric multistage permanent magnet vertically, and certain angle that this multistage permanent magnet is along the circumferential direction staggered successively.For certain permanent-magnet servo motor coordinated, adopt this kind of method can reach the effect reducing slot effect very well, and technique is simple, is easy to realize, there is certain productive value.
Summary of the invention
The purpose of this utility model is to provide a kind of segment permanent magnet servo motor rotor.
For achieving the above object, the utility model provides following technical scheme: a kind of segment permanent magnet servo motor rotor, comprises rotating shaft, rotor core, rivet, end plate and magnet steel; Bonding magnetic steel is on rotor core, and rotor core is divided into two sections, left and right, left section of rotor core and right section of rotor core Opposite direction connection; With rivet, two iron leg cores and end plate are riveted together, are assembled into one with described magnet steel, rotating shaft; Because iron core rivet hole opposing polarities has certain skew, therefore two sections of magnetic poles achieve the effect of grading excursion.
Further, the hole described rotor core having certain angle to offset.
Further, described rotor core circumference is divided into two sections, and by Opposite direction connection, and two iron leg cores along the circumferential direction stagger certain angle.
Compared with prior art, the beneficial effects of the utility model are: this permanent magnetic servo motor rotor, adopt the direction of Opposite direction connection, reach the effect of magnetic pole segment fault pole, to reduce motor slot effect, be easy to realize small lot, enhance product performance, reduce manufacturing cost.
Integrated operation is simple, and cost is low, applied range, practical.
Accompanying drawing explanation
Fig. 1 is left section of rotor core schematic diagram of the present utility model.
Fig. 2 is right-hand member rotor core Opposite direction connection schematic diagram of the present utility model.
Fig. 3 is rotor structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 3, the utility model provides a kind of technical scheme: a kind of magnetic pole segmentation permanent magnetic servo motor rotor, comprises magnet steel 1, rotor core 2, end plate 3, rotating shaft 4 and rivet 5; Described magnet steel 1 is bonded on rotor core 2, by left section of rotor core 21 and right-hand member rotor core 22 Opposite direction connection; Rotor core 2 and end plate 3 are riveted together with rivet 5, last and rotating shaft 4 is assembled into one; Rivet hole opposing polarities on rotor core has certain angular deflection, and therefore the core magnetic pole of Opposite direction connection along the circumferential direction staggers certain angle.
Further, described rotor core 2 offers the hole of skew certain angle, consult Fig. 1.
Further, described left section of rotor core and right section of rotor core Opposite direction connection, two sections of magnetic poles along the circumferential direction stagger certain angle, consult Fig. 2.
The utility model when designing, because points two sections just obviously can reach the effects weakening slot effect, for the ease of manufacture, by the perforate of rotor punching being done the skew of certain angle, in the situation not increasing any technology difficulty, by reverse means, realize the effect of segment fault pole.Produce with normal conventional in whole production process, under the prerequisite not increasing cost, achieve the optimization of motor scheme.Compare tradition tiltedly the technology difficulty brought of pole mode and manufacturing cost raise, the design can be beneficial to and realize batch production, benefit increases.For the motor of ad hoc structure, there is certain reference value.
