Abstract

The utility model discloses a permanent-magnet motor skewed-pole rotor structure which comprises a rotating shaft and a rotor module. The shaft diameter of the rotating shaft is assembled in a core inner hole of the rotor module. A first plane, a second plane, a third plane and a fourth plane on the rotating shaft respectively fit inner hole planes of cores of a first rotor module, a second rotor module, a third rotor module and a fourth rotor module in sequence to enable steel magnets on the rotor module to be spirally misaligned, namely, achieve the effect of a skewing-pole rotor. The permanent-magnet motor skewed-pole rotor structure has the following advantages: the core adopts a laminations structure, which can reduce the eddy current loss of the motor; rotor parts are simple to process, and especially, core punching sheets are high in punching efficiency; the skewed poles of the rotor are directly formed in rotor pressing, thus greatly improving the labor productivity; and the motor rotor has the advantages of simple structure and convenient processing and manufacturing processes.

Description

A kind of magneto skewed pole rotor structure

Technical field

The utility model relates to a kind of rotor structure of motor, relates in particular to a kind of skewed pole rotor structure of magneto.

Background technology

Conventionally, rotor comprises iron core and rotating shaft, and the rotor of magneto also contains magnet steel, different motors can be because its magnetic circuit requires different, the structure of rotor also can be different, paste the rotor of magnet steel for oblique extremely surface, and its structure often iron core adopts integral type mild steel entirety car system to form, in the time pasting magnet steel, the mode that forms certain spiral angle with rotor axis pasted into by magnet steel by the frock clamp location that utilizes having; Have plenty of in advance at rotor core Surface Machining location notch, make location notch and rotor axis direction form the form at step helix angle, utilize the boss of positioning magnetic steel to position, the magnet steel after stickup and rotor axis also form the form of step helix; Though can reach the object of the oblique utmost point with upper type, there is the defect of rotor core processed complex and assembling trouble, simultaneously also because rotor core is to be formed by overall steel part car system, in the time that motor moves, eddy current loss can increase, and reduces the power output of motor.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of magneto skewed pole rotor structure.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of magneto skewed pole rotor structure, comprise rotating shaft, rotor module, the diameter of axle of described rotating shaft is loaded in the iron core endoporus of rotor module, and the first plane, the second plane, the 3rd plane and Siping City's face in rotating shaft fits with the endoporus plane of the iron core of the first rotor module, the second rotor module, third trochanter module and fourth trochanter module respectively in order, make the magnet steel in rotor module form spiral helicine dislocation form, reach the effect of skewed-rotor.

Described rotor module comprises iron core, magnet steel and every magnetic stripe, iron core is provided with iron core endoporus and endoporus plane, it is folded thick consistent with the axial length of magnet steel, fold into the form of module, each iron core module lamination is auto-buckled type structure, described magnet steel is pasted on the outer round surface of iron core, and between magnet steel, has and carry out spaced apart every magnetic stripe.

Described rotating shaft is provided with the diameter of axle, guide end, the first plane, the second plane, the 3rd plane and Siping City's face.

The described diameter of axle and iron core endoporus adopt interference fit, and the endoporus plane of the first plane, the second plane, the 3rd plane and Siping City's face and the iron core of rotating shaft adopts interference fits.

The guide end of described rotating shaft and iron core endoporus adopt matched in clearance.

Described is made up of non-magnet material every magnetic stripe.

Compared with prior art, the utility model has the advantages that iron core adopts the structure of lamination can reduce the eddy current loss of motor, the processing of rotor component is simple, and particularly core stamping has advantages of that punching efficiency is high, the oblique utmost point of rotor directly forms during by rotor press-mounting, greatly raises labour productivity.Owing to adopting interference fit between iron core endoporus and the diameter of axle, eliminate the phenomenon of axial play, the endoporus plane of iron core and the first plane of rotating shaft, the second plane, the 3rd plane and quadriplanar laminating can effectively prevent that the issuable rotor module pine of high-torque from turning phenomenon, this rotor has simple in structure, and process for machining and manufacturing is feature easily.

Embodiment

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

As shown in Figure 1, a kind of magneto skewed pole rotor structure, comprise rotating shaft 1, rotor module 2, the skewed pole rotor that the present embodiment is is 4 modules to rotor module 2 is that example is described, figure rotor module 2 is again with the first rotor module 2-1, the second rotor module 2-2, title and the numbering of third trochanter module 2-3 and fourth trochanter module 2-4 are distinguished respectively statement, so that to the description of embodiment, as Fig. 2, shown in Fig. 3, rotating shaft 2 is provided with the diameter of axle 11, guide end 12, the first plane 11-1, the second plane 11-2, the 3rd plane 11-3 and the face 11-4 of Siping City, as Fig. 4, shown in Fig. 5, the iron core 23 of rotor module 2 is provided with iron core endoporus 232 and endoporus plane 231, be overrided to form in the mode of self-clinching by punching, fastened with glue magnet steel 21 and every magnetic stripe 22 of the outer round surface of iron core 23, every magnetic stripe 22 respectively between the N of magnet steel 21 utmost point and the S utmost point, in the time of rotor press-mounting, first the leading end of rotating shaft 1 12 is inserted in the iron core endoporus 232 of the first rotor module 2-1, then by the endoporus plane 231 of the first plane 11-1 alignment iron core 23 of rotating shaft 1, and the first plane 11-1 and endoporus plane 231 are fitted, again the diameter of axle of rotating shaft 1 11 is pressed in iron core endoporus 232 completely, use the same method the leading end of rotating shaft 1 12 is inserted in the iron core endoporus 232 of the second rotor module 2-2, then by the endoporus plane 231 of the second plane 11-2 alignment iron core 23 of rotating shaft 1, and the second plane 11-2 and endoporus plane 231 are fitted, again the diameter of axle of rotating shaft 1 11 is pressed in iron core endoporus 232 completely, by that analogy, third trochanter module 2-3 and fourth trochanter module 2-4 are pressed into this, even if form magneto skewed pole rotor as shown in Figure 1.

In above-described embodiment, between iron core endoporus 232 and the diameter of axle 11, adopt interference fit, eliminate the phenomenon of axial play, the endoporus plane 231 of iron core 23 can effectively prevent that with the laminating of the first plane 11-1, the second plane 11-2, the 3rd plane 11-3 and the face 11-4 of Siping City of rotating shaft 1 pine of the issuable rotor module 2 of high-torque from turning phenomenon.

Above-described embodiment is just to a kind of explanation of the present utility model, the not restriction to the utility model rights protection.
