Description
Technical field
It the utility model is related to motor device field, more particularly to a kind of structure of rotor.
Background technology
Magnetic flux of the magneto per pole is in parallel by two pieces of permanent magnets and is provided, it can effectively improve stator and rotor
The magnetic flux density of intermediate air gap, and then increase the output performance of motor, this mode is widely used by industry all the time.
Among the structure of rotor, particularly large-size machine, the structure principal mode that shaft coordinates with it be all rotor core surface or
In iron core outer edge position, permanent magnet is set.However, since rotor quality is excessive in existing structure, cause the weight of motor can not
Reduce, part motor employs the mode of the grooving in rotor core to mitigate weight, but the mode of this grooving is due to being
Scattered, and the position of part grooving needs the calculating for carrying out magnetic leakage in advance and the technique for considering grooving, thus significantly
Limit the production of motor.Furthermore the mode of grooving is hollowed out since portion can not be maximized effectively and accurately, thus its is right
Still there is certain limitation space in motor overall quality.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of motor rotor construction for advantageously reducing motor weight.
It is achieved through the following technical solutions above-mentioned purpose：
A kind of light-weighted concentrated magnetic permanent magnet machine rotor, including rotor core and multiple permanent magnets, the rotor core
Upper to have multiple mounting grooves towards axle center, the permanent magnet is respectively arranged in the multiple mounting groove, adjacent permanent magnet
Formed with magnetic bridge between lower section, multiple gaps hollowed out are equipped between the axle center of rotor core and outer edge, between each gap
Equipped with support column, the support column is equal with the distance between the outer edge of rotor core, and support column is contacted with rotor core
The area of section at position be more than support column in the middle part of area of section, the rotor core outer edge by it is multiple be combined into a pair
Permanent magnet is to composition, and each pair permanent magnet is to being respectively placed in the inner side of a segmental arc.
Further described as to a kind of above-mentioned light-weighted concentrated magnetic permanent magnet machine rotor, outside the rotor core
It is surrounded by the stator that section is toroidal arrangement.
It is further described as to a kind of above-mentioned light-weighted concentrated magnetic permanent magnet machine rotor, the rotor core
It is equidistant air gap or non-equidistant air gap between stator medial surface.
Further described as to a kind of above-mentioned light-weighted concentrated magnetic permanent magnet machine rotor, the support column is one
End cap, the end cap are placed on the center that rotor core outer edge and shaft pass through end cap, end cap and rotor core outer edge it
Between be equipped with fixed screw, or end cap and rotor core are integrally fixed in shaft.
Further described as to a kind of above-mentioned light-weighted concentrated magnetic permanent magnet machine rotor, the support column is " work "
The support shaft of font, shaft are placed between each support the tip of the axis.
The beneficial effects of the utility model are：For micro-machine, carry out borehole in internal rotor and form notch, lacked at this
Reach the effect for eliminating stress near mouthful, while itself also can eliminate what is outwards expanded during rotor and shaft cooperation
Stress, prevents from causing punching outwards expansion to cause assembly problem.For large-size machine, by the rotor core of motor and shaft it
Between leave support column, it is connected using support column with shaft, drives whole rotor to rotate, due to staying between the support column
Sky, can greatly reduce the overall weight of motor, while can also keep the stability of Distribution of Magnetic Field, reduce the hair of leakage field phenomenon
It is raw；In post design is supported, it can ensure that support column and the contact surface at iron core both ends are closely tied using I-shaped form
Close, and support column is distributed in each position of iron core inner ring, support column is driven uniform stressed when rotating, and ensures support strength；
And end cover structure then easily carries out the finishing of individual components, it is fixed on rotor core again after can first independently end cap be molded
Interior, easy for assembly and formation highly effective, is more suitable for industrialization.
