Abstract
The invention discloses a rotor sheet for an automotive permanent-magnet synchronous generator. The rotor sheet comprises a rotor sheet body, wherein a plurality of wide grooves and narrow grooves for placing permanent magnets are uniformly formed in the rotor sheet body; tensioning holes are formed between the wide grooves and the narrow grooves; second broken bridges are arranged at the outer sides of the width grooves; first broken bridges are arranged between the wide grooves and the narrow grooves. The rotor sheet disclosed by the invention is capable of effectively reducing the leakage flux of a motor, increasing the utilization rate of the permanent magnets, reducing the number of used permanent magnets, and reducing the material cost of the motor.
Description
Technical field
The present invention relates to a kind of rotor lamination of generator, particularly relate to the punching of a kind of automobile permanent magnet synchronous generator rotor, belong to electric field of components.
Background technology
In recent years, automobile permanent magnet synchronous generator because its efficiency high, low speed power supply performance is good, voltage regulation is low, the advantage such as simple in structure, reliable operation, stable performance more and more applied.The rotor punching of car permanent magneto has surface-type and built-in two kinds of forms, and wherein the application of built-in rotor punching is comparatively extensive.Built-in rotor punching leakage field is larger, and the effective rate of utilization of permanent magnet is lower, has increased the material cost of motor.
For reducing leakage field, existing car permanent magneto arranges every magnetic bridge on rotor punching, but every magnetic effect not obvious, and rotor punching reliability is low.
Summary of the invention
Goal of the invention:
The object of the invention is to propose one and can reduce leakage field, can ensure again mechanical strength, the automobile permanent magnet synchronous generator rotor punching that reliability is high.
Technical scheme:
The punching of a kind of automobile permanent magnet synchronous generator rotor, comprise rotor punching body, it is characterized in that: on rotor punching body, be evenly provided with multiple for placing sipes and the narrow groove of permanent magnet, between sipes and narrow groove, be provided with tension hole, there is the second bridge cut-off in the arranged outside of sipes, between sipes and narrow groove, be provided with the first bridge cut-off.
On rotor punching body excircle, be evenly provided with sipes, be equipped with narrow groove in the left and right sides, inner side of each sipes.
Between the narrow groove that the first bridge cut-off is arranged on sipes and any side being adjacent and is homonymy.
The quantity of described sipes and narrow groove is corresponding with motor pole number.
Advantage and effect:
The punching of this automobile permanent magnet synchronous generator rotor of the present invention, has the following advantages and beneficial effect:
(1) adopt bridge cut-off structure, effectively reduced rotor leakage field;
(2) effectively ensure mechanical strength, reliability is high;
(3) utilance of raising permanent magnet, reduces permanent magnet consumption, reduces motor material cost.
brief description of the drawings:
Fig. 1 is overall structure schematic diagram of the present invention.
Description of reference numerals:
In figure: 1-sipes, 2-the first bridge cut-off, 3-strains hole, the narrow groove of 4-, 5-the second bridge cut-off, 6-rotor punching body.
embodiment:
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1, the present invention is the rotor punching being applied on car permanent magneto, embodiment is four utmost point lamination structures, rotor punching is completely circular structure, comprise rotor punching body 6, it is characterized in that: on rotor punching body 6, be evenly provided with multiple for placing sipes 1 and the narrow groove 4 of permanent magnet, between described sipes 1 and narrow groove 4, be provided with tension hole 3, for punching axial tightening; There is the second bridge cut-off 5 in the arranged outside of sipes 1, between sipes 1 and narrow groove 4, be provided with the first bridge cut-off 2, the ability that can further increase rotor punching and reduce leakage field is set like this, effectively reduce rotor leakage field.
On rotor punching body 6 excircles, be evenly provided with sipes 1, be equipped with narrow groove 4 in the left and right sides, inner side of each sipes 1.
Between the narrow groove 4 that the first bridge cut-off 2 is arranged on sipes 1 and any side being adjacent and is homonymy, the first bridge cut-off all can be set between the narrow groove 4 of the left and right sides being adjacent at sipes 1, be arranged on when left side all in left side, while being arranged on right side all on right side.
The quantity of described sipes 1 and narrow groove 4 is corresponding with motor pole number.
The quantity in described tension hole 3 is corresponding with the number of poles of motor, and the diameter in tension hole can be arranged between 5～10mm, now best results, and tension Kong Tai little affect the tension intensity of rotor punching, strains Kong Tai great, can affect the leakage field of motor.
The width of the first bridge cut-off 2 is a, and the width of narrow groove 4 ends is b, and the width a of the first bridge cut-off 2 and the width b of narrow groove 4 should meet:
; The width of the second bridge cut-off 5 is a1, and the width of sipes 1 is b1, should meet: a1=between the width of the second bridge cut-off 5 and the width of sipes 1
b1.Mechanical strength is set so high, effective every magnetic.
When the present invention uses:
Current existing rotor punching, without bridge cut-off, is ined succession, and leakage field phenomenon is serious, and the present invention is provided with the first bridge cut-off 2 between sipes 1 and narrow groove 4, and at sipes 1 arranged outside the second bridge cut-off 5, efficiently solves this problem.
Rotor punching in use, the permanent magnet being arranged in sipes 1 and narrow groove 4 outwards sends total magnetic flux, total magnetic flux is main flux and leakage flux sum, and wherein main flux is useful magnetic flux, and leakage flux is harmful magnetic flux, leakage flux is that main flux is fewer more, more unfavorable to motor, the first bridge cut-off 2 is being set between sipes 1 and narrow groove 4 and after sipes 1 arranged outside the second bridge cut-off 5, is effectively stoping leakage field, reduce leakage flux, the main flux that motor sends is increased greatly.So just can reduce the consumption of permanent magnet, effectively save the production cost of motor.
