Abstract
The utility model discloses a cylinder iron core which is characterized in that the longitudinal section of the cylinder of the iron core body is provided with a joint cutting or a notch used for shutting off the cycle of the eddy current; the iron core body is capable of being a composite structure as one-piece iron core section, and a stamped steel iterative structure with a joint cutting even more; and wherein the slot effectively restrains the eddy current loss of the electric machine, increases the efficiency, makes the output power of the electric machine increased obviously, and reduces obviously the temperature rise. Thereby the utility model has the advantages of simple and rational structure, low cost, reliable operation ad convenient making, moreover, the cylinder iron core is in favor of making the equipment miniaturized; so the utility model is widely suitable for being used in the equipment such as punch, plunger oil pump, elevator, curtain device and electromagnet, etc.
Description
Technical field
The utility model relates to motor, the magnetic circuit iron core parts that specifically a kind of motor is used.
Background technology
Iron core is the significant components that is operated in the electromechanical equipment in the electromagnetic field.In alternating electromagnetic field, the iron core iron loss that invariably accompanies, the effect of its eddy current loss is equivalent to exist the secondary coil by short circuit.Eddy current loss is under some occasion even can make the useful flux rapid drawdown, and reduction causes exerting oneself.The eddy current loss of the cylindrical shape iron core in the existing linear electric motors is in fact very outstanding.
Technology contents
The utility model is intended to solve the eddy current loss problem of above-mentioned reduction cylindrical shape iron core.
Operation principle of the present utility model is based on the eddy current loop on the iron-core workpiece is effectively blocked.
Cylinder type iron core of the present utility model comprises iron-core workpiece, it is characterized in that the cylindrical shell longitudinal section of said iron-core workpiece is provided with joint-cutting or the fluting that blocking-up eddy current loop is used.
Described iron-core workpiece is the iron-core workpiece that is assembled by the unit core packet of being with joint-cutting or fluting.
Described iron-core workpiece is formed by stacking by the punching of annular, and each punching is provided with one or more joint-cutting.
The joint-cutting of described punching is the joint-cutting of incomplete cut-off.
Be provided with winding in the described iron-core workpiece, constitute the elementary of motor by winding and iron core.
Good effect of the present utility model is:
1, simple and reasonable, to make, assembling processing is extremely convenient, with low cost, experiment shows that its operation is very reliable;
2, can suppress the eddy current loss of motor effectively, electric efficiency is improved, its power output phenomenal growth, temperature rise obviously reduces.
3, owing to the efficient height, under the condition of set output, the overall dimension of motor device can be done forr a short time.

Embodiment
Further specify embodiment shown in the drawings below:
Referring to accompanying drawing.The cylindrical linear motor that shown in Figure 1 is constitutes with the cylindrical shape iron core, mover 5 is contained among the stator 4, and wherein iron core is made up of iron-core workpiece, and iron-core workpiece is the iron-core workpiece by band joint-cutting or 3 the whole unit core packet assembling of slotting.Whole core packet processes with ferromagnetic material, wherein is provided with to be used to that the winding cavity of winding is installed and to be used to go between and the slotted eye of mechanical fixation.Iron-core workpiece is fixing by end cap 6, and end cap 6 also plays the magnetic conduction effect simultaneously as the part of iron core.The cylindrical on the whole shape of iron-core workpiece.The 2nd, the winding of loop configuration is embedded in iron-core workpiece.On the iron-core workpiece of cylinder type iron core, be provided with the joint-cutting of using in blocking-up eddy current loop along the cylindrical shell longitudinal section of iron-core workpiece or slot 3.Joint-cutting blocks the eddy current loop just, plays inhibitory action, and to several nothing influences of magnetic circuit.The package assembly of the monoblock core packet shown in this example and another kind of structure by the punching section of being overlapped into, its assembling processing is all very convenient.In addition, the coil in this device does not have termination part (after interconnecting between each coil, drawing external terminal), and all conductors all are live parts, the stock utilization height, and relative cost is low.After the energising, under controlled situation, move on request.This linear electric motors are usually used in stamping machine, plunger oil pump, elevator, window curtain driving mechanism and the electromagnet.Because of its winding coil plane and punching plane parallel, just in time on the plane of core lamination stack, the eddy current loop that each punching constitutes is blocked at joint-cutting or fluting position, so can not form the eddy current loop, iron loss is reduced in the vortex field, and temperature rise reduces.
Fig. 2 is the structure that is recorded in a kind of low iron loss of document, employing be the superimposed package assembly of punching.The lamination of iron core 1 be divided into four groups circumferentially uniform, and vertically be provided with, winding 2 is embedded in the groove of core stamping, is fixed on simultaneously on the ring set 8, ring set 8 is simultaneously as the part of magnetic circuit.It can effectively suppress eddy current loss, and its plane, eddy current loop is vertical with the lamination face, and the insulant on the lamination face plays blocking effect.But the process and assemble of this iron core and mechanical fixation be difficulty very, and the air gap precision between stator and the mover 5 and the uniformity are difficult to also guarantee that the space hold rate of machinery is also low, so the application of fading out already.
Fig. 3-7 has provided the organization plan of various core stamping joint-cutting modes.Usually joint-cutting or fluting are provided with the requirement that a narrow slit can satisfy its circulation loop of blocking-up, establish two joint-cuttings, three joint-cuttings can be guaranteed barrier effect, but are not easy to assembling and fixing.It is opposite that 10 of incomplete joint-cuttings are set, its assembling and convenient fixing, and just barrier effect is poor slightly.
The foregoing description is simple in structure, and is with low cost, and eddy current loss is little, and the efficient height makes the phenomenal growth of motor power output, and temperature rise obviously reduces.
