Abstract
The invention discloses the permanent magnet mounting structure of a kind of reel motor, two peripheral side of described permanent magnet are the tapered plane shape of inner side top rake shape, fastened by vertical card article card between described adjacent permanent magnet, inner walls between the peripheral side of described two adjacent permanent magnets is provided with axially extended groove, and in described groove, big mouth is little；Described vertical card article radially one end nesting is interspersed in groove and cross sectional shape matches with groove, and radially the circumferential both sides of the other end are clamped in the peripheral side of adjacent permanent magnet respectively.The invention has the beneficial effects as follows: by arranging the little interior big groove of mouth in the inner walls between two permanent magnets, the vertical card article of the side being interspersed in groove, other end clamping adjacent permanent magnet with radially one end nesting is combined, achieve and can fasten permanent magnet without screw, installation difficulty is little and precision is high, improves production efficiency while reducing labor intensity.
Description
Technical field
The present invention relates to the permanent magnet mounting structure of a kind of reel motor, be particularly suited for low-speed big external rotor permanent magnet and synchronize
Motor.
Background technology
Reel motor, namely the outer rotor of outer rotor motor is generally by the rotor case of tubular and be positioned at described turning
The permanent magnet composition of sub-case inside, described permanent magnet is fixed on the inwall of rotor case by the way of bonding or screw fastening
On, it is consequently formed the excitation field of rotor, when needs motor has low-speed big output, generally requires increase permanent magnet
Number, to optimize the distribution of permanent magnet, eliminate or reduce pulsating torque, reduce copper loss and iron loss, in the case, Jin Jintong
Crossing bonding to carry out the installation of permanent magnet and fix, the fastness of bonding is poor, and reliability is low, is unfavorable for ensureing quality, and passes through forever
Magnet carries out screw fastening, and not only the installation exercise amount of permanent magnet is big, and owing to permanent magnet machinability is poor, also at very great Cheng
Improve production cost on degree, reduce reliability, it is difficult to ensure quality.
Chinese patent (application number: CN201410414146.0) discloses the permanent magnet of a kind of external rotor electric machine and installs knot
Structure, its main technical schemes is to arrange end compression bar between adjacent permanent magnet, and the peripheral side of end compression bar compresses adjacent permanent magnet
Both sides end face, in the axial direction end compression bar is screwed on electric machine casing, although this structure is more convenient than said structure,
But need nonetheless remain for screw to fix, installation workload is still big, and the when that additionally in rotor case, the degree of depth being big, installation difficulty promotes
And screw fix accuracy reduce, it is impossible to ensure product quality.
Summary of the invention
In order to overcome drawbacks described above, the present invention provides the permanent magnet mounting structure of a kind of reel motor.
To achieve these goals, the technical scheme is that the permanent magnet mounting structure of a kind of reel motor, including
The rotor case of tubular, described inner walls is provided with some permanent magnets, and described some permanent magnets use identical tile-type hexahedro
Body structure and circumferentially regularly arranged with axial both direction in described rotor case, two peripheral side of described permanent magnet
In the tapered plane shape of inner side top rake shape, fastened by vertical card article card between described adjacent permanent magnet, described adjacent two
Inner walls between the peripheral side of permanent magnet is provided with axially extended groove, and in described groove, big mouth is little；Described vertical card article
Radially one end nesting is interspersed in groove and cross sectional shape matches with groove, and radially the circumferential both sides of the other end are distinguished
It is clamped in the peripheral side of adjacent permanent magnet.
Further, preferred as one, described channel section is shaped as isosceles trapezoid or T-shaped or dovetail groove.
Further, preferred as one, described vertical card article non-magnet material.
Further, preferred as one, join for hot charging between described vertical card article and groove.
The invention has the beneficial effects as follows: little interior big recessed by arranging mouth in the inner walls between two permanent magnets
Groove, the vertical card article of the side being interspersed in groove, other end clamping adjacent permanent magnet with radially one end nesting is combined, it is achieved that no
Can fasten permanent magnet with screw, installation difficulty is little and precision is high, improves production efficiency while reducing labor intensity.
Accompanying drawing explanation
Fig. 1 is the structural representation sketch of the present invention.
Fig. 2 is the structural representation of the another kind of shaped recesses of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described further.
As it is shown in figure 1, the permanent magnet mounting structure of a kind of reel motor, including the rotor case 1 of tubular, described housing 1
Inwall is provided with some permanent magnets 2, and described some permanent magnets 2 use identical tile-type hexahedron structure and at described rotor case
In 1 circumferentially regularly arranged with axial both direction, two peripheral side of described permanent magnet 2 are the tapered plane of inner side top rake shape
Shape, between described adjacent permanent magnet 2 by vertical card article 3 card fasten, the peripheral side of described two adjacent permanent magnets 2 it
Between inner walls be provided with axially extended groove 4, in described groove 4, big mouth is little, is typically set to isosceles trapezoid；Described vertical card article
3 in radially one end nesting is interspersed in groove 4 and cross sectional shape matches with groove 4, the radially circumferential both sides of the other end
It is clamped on respectively in the peripheral side of adjacent permanent magnet 2, vertical card article non-magnet material.
As in figure 2 it is shown, in an alternative embodiment of the invention, described groove 4 cross sectional shape is T-shaped.
In actual use, groove 4 cross sectional shape of the present invention may be arranged as dove tail shape or big mouth in other
Little caulking groove shape.
Making assembling more close and firm to allow, vertical preferred version between card article and groove is that hot charging is joined.
Technical scheme is not limited to the restriction of above-mentioned specific embodiment, every does according to technical scheme
The technology deformation gone out, within each falling within protection scope of the present invention.
