Description
Technical field
This practical linear motor field more particularly to a kind of ironless linear motors stator of unilateral magnet.
Background technique
Existing ironless linear motors stator structure is made of upper magnet yoke, central strip, lower yoke, upper magnet, lower magnet,
Upper and lower magnetic yoke is connected by screw to central strip, and upper magnet is bonded on upper magnet yoke, and lower magnet is bonded in lower yoke.It is this
Structure has certain versatility, but some miniature ironless linear motors of needs on the ironless linear motors of middle high thrust
Occasion under, split type structure just will receive limitation to the selection of processing, assembling and screw.
In the motor that the place of narrow space uses, stator needs are smaller, and the magnet on upper magnet yoke and lower yoke needs
Design it is very thin, but if magnet processing is too thin, when assembling, is really easy to break.
Utility model content
The purpose of this utility model is to provide a kind of ironless linear motors stators of unilateral magnet, to solve existing nothing
The magnet installation of iron core linear motor stator electric is easy the problem of splitting.
The utility model embodiment is achieved in that a kind of ironless linear motors stator of unilateral magnet, including magnetic
Yoke body, several magnet, the magnetic yoke body be equipped with upper magnet yoke portion and with symmetrically arranged lower yoke portion, the upper magnet yoke portion, if
The inside that the upper magnet yoke portion or lower yoke portion are set at dry magnet interval；The magnetic yoke body is in concave character type and is integrated into
Type.
Further, the spacing in magnet and lower yoke portion is 0.8-1.2 times of magnet thickness.
Further, the thickness in upper magnet yoke portion and lower yoke portion is greater than or equal to the thickness of the magnet.
Further, the magnetic yoke body further includes interconnecting piece, the interconnecting piece and the upper magnet yoke portion and lower yoke portion one
It is body formed.
Further, the direction of the interconnecting piece is provided with threaded hole in the upper magnet yoke portion or lower yoke portion.
The utility model embodiment provides a kind of ironless linear motors stator of unilateral magnet, if including magnetic yoke body,
Dry magnet, the magnetic yoke body be equipped with upper magnet yoke portion and with symmetrically arranged lower yoke portion, the upper magnet yoke portion, several magnetic
The setting upper magnet yoke portion at iron interval or the inside in lower yoke portion；The magnetic yoke body is in concave character type and is integrally formed, and enhances
The intensity of magnetic yoke body；Magnet is arranged in the side magnetic yoke portion of the magnetic yoke body, and the magnetic yoke portion of the other side is not provided with magnet, this mode
The thickness that magnet can be increased is avoided because of the too thin of Magnet design and the fragmentation in assembling.
Detailed description of the invention

Attached drawing needed in description is briefly described, it should be apparent that, the accompanying drawings in the following description is only that this is practical new
Some embodiments of type for those of ordinary skill in the art without any creative labor, can be with
It obtains other drawings based on these drawings.
The structural schematic diagram of the ironless linear motors stator of Fig. 1 unilateral magnet provided by the embodiment of the utility model.
Fig. 2 is the side view of Fig. 1.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figure 1, 2, the utility model embodiment provides a kind of ironless linear motors stator 100 of unilateral magnet,
Including magnetic yoke body 110, several magnet 120, the magnetic yoke body 110 be equipped with upper magnet yoke portion 111 and with the upper magnet yoke portion 111
Symmetrically arranged lower yoke portion 112, the setting upper magnet yoke portion 111 at several magnet 120 interval or lower yoke portion 112 it is interior
Side；The magnetic yoke body 110 is in character cut in bas-relief and is integrally formed.
Ironless linear motors stator 100 provided by the embodiment of the utility model is using the magnetic for being in character cut in bas-relief and being integrally formed
Yoke body 110 enhances the intensity of magnetic yoke body 110；Magnet, the magnetic yoke of the other side is arranged in the side magnetic yoke portion of the magnetic yoke body 110
Portion is not provided with magnet, this mode can increase the thickness of magnet, avoids because of the too thin of Magnet design and the fragmentation in assembling.
Specifically, the upper magnet yoke portion 111 of the present embodiment is equipped with magnet 120 towards the side in the lower yoke portion 112；Lower magnetic
Yoke portion 112 and magnet 120, upper magnet yoke portion 111 constitute field circuit, and the lower yoke portion of magnet side is not provided with due to retaining
112, so that magnetic field strength enhances.
Certainly, in other embodiments, the magnet also can be set in the inside in the lower yoke portion 112, corresponding,
Magnet is arranged in 111 top of upper magnet yoke portion.
Further, the spacing in magnet 120 and lower yoke portion 112 is 0.8-1.2 times of magnet thickness.
In the present embodiment, the spacing in magnet 120 and lower yoke portion 112 is 1 times of magnet thickness.
Further, the thickness in upper magnet yoke portion 111 and lower yoke portion 112 be respectively greater than or equal to the magnet 120 thickness
Degree to guarantee to obtain ideal magnetic field strength, and is unlikely to the flux density saturation of curvature.
Further, the magnetic yoke body 110 further includes interconnecting piece 113, the interconnecting piece 113 and the upper magnet yoke portion and under
Magnetic yoke portion is integrally formed.
Further, the direction of the interconnecting piece 113 is provided with spiral shell in the upper magnet yoke portion 111 or lower yoke portion 112
Pit 130, for realizing the fixed installation of motor.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
