Description

The multipole inner rotor core magnetized in a kind of oblique pole
Technical field
The utility model relates to the multipole inner rotor core magnetized in a kind of oblique pole, particularly relates to a kind of slowspeed machine rotor structure of multipole.
Background technology
At present, in the slowspeed machine of multipole multiple-grooved, rotor magnetic pole is more, and when rotor length is longer, because every block magnet steel can not be processed long, need to be spliced into Len req by some blocks of magnet steel, rotor magnetic steel number just seems many especially.In the fabrication process, the bonding man-hour of magnet steel is more, and because every pole is all on one block of magnet steel, skewed-rotor can only lean on segmentation to realize, and this just has higher requirement to the press-loading device of iron core, needs special equipment, and segmentation rotates press-in iron core.Magnetized head also needs special segmentation oblique pole magnetizing clamp.Batch production process in, whole bottleneck just rotor magnetic steel bonding on.How effectively to reduce the used time amount of this procedure, reduce equipment investment and don't affect the performance of product, what just seem very in whole manufacture process is important.
Conventional skewed pole rotor, or adopt the oblique pole of overall magnet ring to magnetize, or adopt the mode of the oblique pole of segmentation, certain angle that staggered by magnet steel is amplexiformed, overall magnet ring, particularly large diameter magnet ring, during blank sintering, magnetic material preliminary treatment is difficult to realize, and overall magnet ring is usually used in the structure of minor diameter.In multisegmented rotor, the oblique pole of segmentation, magnet steel quantity is more, and in process of production, magnet steel bonding time-consuming more is a bottleneck of productive temp.
Summary of the invention
The purpose of this utility model is the multipole inner rotor core providing a kind of oblique pole to magnetize.
For achieving the above object, the utility model provides following technical scheme: the multipole inner rotor core magnetized in a kind of oblique pole, comprises rotor punching, magnet steel fixed cover and magnet steel; Described magnet steel is arranged in magnet steel fixed cover; Described rotor punching is arranged on rotor; Bonding glue is provided with between described rotor punching and magnet steel.
Further, described magnet steel quantity is the half of number of poles, magnetizes in oblique pole, and polylith magnet steel forms a magnet ring, and being had a common boundary by two magnet steel is placed in a magnetic pole.
Compared with prior art, the beneficial effects of the utility model are: the multipole inner rotor core magnetized in this oblique pole, form a magnet ring with multi-disc arc magnet steel, reduce magnet steel quantity, save production hour, reduce production cost.Different pole is placed in same magnet steel, the intersection of arc magnet steel be placed on one extremely in, the magnetic reduced in this gap by the mode of oblique pole is close be evenly distributed in one extremely in, reduce production cost, decrease the input of equipment, be also easy to mass production.
Accompanying drawing explanation
Fig. 1 is the cutaway view of multipole inner rotor core mid point of the present utility model.
Fig. 2 is the schematic diagram that magnetizes of skewed pole rotor 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. 1 ~ 2, the utility model provides a kind of technical scheme: the multipole inner rotor core magnetized in a kind of oblique pole, comprises rotor punching 1, magnet steel fixed cover 2 and magnet steel 3; Described magnet steel 3 is arranged in magnet steel fixed cover 2; Described rotor punching 1 is arranged on rotor; The glue 4 that bonds is provided with between described rotor punching 1 and magnet steel 3.
Further, described magnet steel 3 quantity is the half of number of poles, magnetizes in oblique pole, and polylith magnet steel 3 forms a magnet ring, and being had a common boundary by two magnet steel is placed in a magnetic pole.
The utility model is when designing: adopt multi-disc arc magnetic sheet to be combined into a magnet ring, in a circumference, motor pole number is 2P, arc magnetic sheet quantity is P, is combined into a circle, in the fabrication process by P block arc magnetic sheet, the bonding quantity of magnet steel is just a half, and saves half man-hour.From the sectional drawing of mid point, N, S alternately magnetize pole, S pole are placed in the center of magnetic sheet, and N pole is made up of the both sides of different two panels magnetic poles, and the gap between two magnetic sheets is just on the neutral line of N pole.When magnetizing, adopt the oblique pole of mode shown in Fig. 2 to magnetize, middle gap will be evenly distributed in N extremely under one section, an instead of point.This extremely under winding cutting magnetic line time, due to oblique pole, the back-emf that winding element length is formed is superimposed by certain phase difference, and the problem that the air gap flux density that between two magnetic sheets, gap is caused weakens by equivalence in certain electrical degree, can affect counter potential waveform hardly.Thus ensure that the electric property of motor.Reach Simplified flowsheet, lower the effect of production cost, be applicable to large batch of production.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
