Abstract
The invention discloses a linear motor stator which is simple in structure, easy to process and can strength magnetic field effects. The linear motor stator comprises a mandrel and magnetic shoes which are absorbed on the mandrel, wherein the mandrel is a soft magnetic tube with a cruciform section; the radial periphery of the mandrel is provided with the magnetic shoes; a spacing piece is arranged between every two axial magnetic shoes; the magnetic shoes are annularly sleeved on the soft magnetic tube with the cruciform section; and two ends of the tube are locked by end covers. The linear motor stator is simple in structure, convenient to mount and easy to produce and manufacture, thus greatly reducing the cost, increasing the power of a linear motor and improving the motion acceleration.
Description
Technical field
The present invention relates to linear electric motors equipment, especially the stator of cylindrical linear electric motors.
Background technology
Along with the quickening of era development step, original speed of production has not satisfied demand, and linear electric motors arise at the historic moment, and at other motor of very fast replacement.Linear electric motors are used in the middle of the various lathes as other motor as power source, along with industrial expansion, the demand of benefit, it needs bigger acceleration come this other induced way except linear electric motors of raising speed not accomplish to the mode that drives with linear electric motors in a series of induced waies, particularly numerical control drilling-milling bed (PCB rig) such as continuous alternative synchronization belt wheel, rack-and-pinion, ball screws.A pith as linear electric motors--stator is also in continuous improvement.
Traditional linear electric motors have flat and cylindrical, the stator of dull and stereotyped linear electric motors be by one one permanent magnet by certain angle, certain distance is parallel to be placed on to fix then from behind on the base plate and with thin plate permanent magnet to be sealed behind; The cylindrical linear motor stator electric is to be adsorbed on above the fuse at a certain distance with plastic dam by one one magnet steel to have blocked effect every magnetic, and steel pipe socket is not met with having again in the outside then, and its two ends, left and right sides are again with screwed end cap and flange pinning.
The shortcoming of above-mentioned prior art scheme is: 1: dull and stereotyped linear motor stator electric can produce very strong suction when being used with mover, this requires the datum level intensity of the workbench of fixing mover and fixed stator fine, be in the same place otherwise can be out of shape and cause mover and stator to be inhaled, the very long required precision of the datum level of fixed stator is higher, otherwise also is drawn onto easily.2: existing cylindrical linear motor stator electric is installed more convenient and only a fraction of datum level is had relatively high expectations, because the gap of mover and stator is big, generally can not held, it to a certain degree is vertically consistent with the direction of motion that but its magnetic line of force comes out to, basically do not play effect, form a very big blind area, reduced magnetic field force greatly, do not have our desired effect.3: producing very big heat in the motion process can not eliminate.
Summary of the invention
At the problems referred to above, the present invention aims to provide a kind of drum type brake linear motor stator electric of increased magnetic field effect of simple in structure, handling ease.Another object of the present invention provides the better linear motor stator electric of radiating effect.
For realizing this technical purpose, the solution of the present invention is: a kind of linear motor stator electric, comprise axle, be adsorbed on the magnetic shoe on the axle, described axle is cross section soft magnetism tubing, the radially embedding all around of axle is with magnetic shoe, axially be provided with on the soft magnetism tubing of the ring-like cross section that is locked of the described magnetic shoe of distance piece between the magnetic shoe at interval in twos, the two ends of described tubing are pinned by end cap.
In order to strengthen radiating effect, the two ends of described axle are equipped with water swivel, can carry out water-cooled.
In order to improve heat resistance, to optimize the magnetic line of force, described magnetic shoe is rubidium iron boron permanent magnet and magnetic line of force radial distribution.。
As further improvement, described axle outermost end magnetic shoe longitudinally has clamp nut to compress.
The stator structure of this programme is simple, and easy for installation being easy to manufactured, and not only greatly reduces cost, and the power that has increased linear electric motors has improved acceleration of motion; In addition, also adopt the structure of water-cooled to strengthen the heat dispersion of stator, reduced the harmful effect that thermal effect is brought.

Fig. 2 is a package assembly of the present invention vertical section schematic diagram.
Embodiment
A kind of linear motor stator electric of the present invention belongs to the stator of cylindrical, and it comprises axle 2, is adsorbed on the magnetic shoe 1 on the axle.As illustrated in fig. 1 and 2, axle 2 of the present invention is cross section soft magnetism tubing, one one magnetic shoe 1 is adsorbed on above the axle, on arranging longitudinally at a certain distance (size of distance has relation with mover) block the effect of playing every magnetic with distance piece 24, steel pipe socket is not met with having again in the outside then, pin with screwed end cap and flange 22 at two ends, the left and right sides again, and then have supporting seat to be fixed on the datum level, easy for installation succinct.
The magnetic shoe 1 of the linear motor stator electric of this most preferred embodiment has all increased composite component, adopt rubidium iron boron permanent magnet, in order to improve heat resistance, it is through special processing, magnetic line of force direction has increased magnetic flux greatly by axially converting to radially, has reduced the blind area, make magnetic field intensity increase several times, power has increased several times when cooperating with mover.
In order to strengthen radiating effect, the two ends of axle 2 are equipped with water swivel 21, can carry out water-cooled, greatly reduce the undesirable heat effect of bringing in the motion process.
As a kind of fixed form of magnetic shoe, described axle 2 outermost end magnetic shoe outer end longitudinally is provided with clamp nut 23 and compresses.
The above; it only is preferred embodiment of the present invention; not in order to restriction the present invention, every foundation technical spirit of the present invention to any trickle modification that above embodiment did, be equal to and replace and improve, all should be included within the protection range of technical solution of the present invention.
