Abstract
The utility model relates to a rectangle roll type linear induction motor, comprising a housing, a primary stage and a secondary stage. The utility model is characterized in that cross sections of the primary stage and the secondary stage are rectangular; inner sides of two end covers are respectively provided with a couple of roll devices between fixed plates at both ends; the secondary stage is clamped between coupled roll devices. Clearance is among end covers, the primary stage and the secondary stage. The motor has little frictional force and better aeration-cooling performance. Rigidity of the secondary stage is better.
Description
The utility model is a kind of motor.
At present, the primary and secondary of common cylinder-shape linear induction motor all is columniform, between this motor is elementary usually, secondary is to rely on end cap directly sliding and running, therefore wearing and tearing easily on secondary.Because of having frictional force, it exists, so the motor pulling force reduces; End cap because of motor contacts with secondary again, the air in the shell is isolated from the outside, so the heat radiation difficulty of motor.Cylindrical in addition secondary rigidity is relatively poor.
In view of the foregoing, the purpose of this utility model provides between a kind of primary and secondary the little and ventilation cooling performance of frictional force linear induction motor preferably.
The purpose of this utility model is achieved in that the primary and secondary of motor all is cuboid, be that its cross section is all rectangular, inboard at elementary two end caps, between the fixed head at elementary two, be provided with a pair of tourelle respectively, make and be the secondary of cuboid and be clipped in the middle of the paired tourelle, end cap, gapped between elementary and secondary, negotiable air.
The tourelle that elementary motion of the present utility model, drive are arranged on the shell rolls on secondary, thereby has realized that the friction loss between the primary and secondary is less; End cap, the gap between elementary and secondary are beneficial to the circulation heat radiation of its gas.The secondary rigidity of cuboid is better.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a longitudinal sectional view of the present utility model;
Fig. 2 is the A-A view of Fig. 1.
With reference to Fig. 1, Fig. 2, the shell 6 of motor is to be made by ferrimagnet, and the double Armco magnetic iron yoke of making motor.Axial fixing plate 5 and end cap 10 are fixed on elementary iron core 9 and coil 7 in the shell 6.Between two fixed head 5, that is to say that between two of iron core 9 and coil 7 and two end caps 10 be provided with a pair of tourelle respectively, this tourelle is fixed on the axle 4 by scroll wheel 3 to be formed.On the axle 4 axle sleeve 12 can be set, the two ends of axle 4 are connected with shell 6.Shell 6 is cuboids, and elementary and tourelle places in it.Cuboid secondary is clipped between two pairs of scroll wheels 3 of two pairs of tourelles, and scroll wheel 3 rolls on secondary.Secondary conductor 1 by rectangle hollow iron core 2 and its appearance is formed.End cap 10, gapped 11 between elementary and secondary, gas can be by flowing therebetween.
During elementary energized, elementary just by the motion on secondary of two pairs of scroll wheels 3.The heat that produces during the motor operation can outwards distribute by gap 11, so motor has the cooling performance that ventilates preferably.
Claims (3)
1, a kind of rectangle rolling type linear induction motor, form by shell [6], primary and secondary, of the present utility modelly be characterised in that the cross section of described primary and secondary is all rectangular, inboard at elementary two end caps [10], between the fixed head [5] at two, be provided with a pair of tourelle respectively, secondary being clipped in the middle of the paired tourelle, end cap [10], elementary and secondary between gapped [11].
2, rectangle rolling type linear induction motor according to claim 1 is characterized in that described tourelle is fixed on axle (4) by scroll wheel (3) and goes up and to form, and the two ends of spool (4) are connected with shell (6).
