Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail.
Embodiment 1:As shown in figs. 1-7, it is the basic embodiment of the present invention.A kind of air-gap armature motor, including stator, rotor and bearing arrangement, its stator is made up of support and air gap armature, and described air gap armature is made up of core stamping 3, coil supports 4, coil 2 and groove contract 1；Described core stamping 3 is the axial cirque structure with dovetail slot；Described coil supports 4 is the isosceles trapezoid wedge-shaped bar being embedded in dovetail slot；Coil 2 is the multiturn fusiformis structure with cooling duct and transposition, is jointly positioned by core stamping 3 and coil supports 4 and is supported.
Embodiment 2:It it is further embodiment.As different from Example 1: described air-gap armature motor, its coil 2 comprises coil lead 21 and coil cooling pipe joint 22.The type of cooling of coil 2 is cold in liquid, and cooling medium is deionized water or transformer oil.Coil 2 is double-deck, the multiturn formed coil of transposition.When coil 2 is then further embodiment for monolayer.Coil 2 is the hollow copper conductor of little line rule, and this hollow copper conductor cross section is square-outside and round-inside shape, square in being elected as foreign side, or cylindrical inner circular, or round outside but spuare inside shape is then further embodiment.Described coil supports 4 material is the composite that magnetic conduction, non-conductive, high intensity and heat conductivility be not excellent, it is possible to elect plastics as.
Embodiment 3:It it is another further embodiment.As different from Example 2: described coil 2 is the combination composition of little line rule hollow copper conductor and little line rule solid copper wire, hollow copper conductor cross section is square-outside and round-inside shape, in being elected as foreign side square, become cylindrical inner circular, or round outside but spuare inside shape be then further embodiment.
Embodiment 4:It it is a kind of coil manufacturing method for air-gap armature motor of the present invention, the steps include: that first the little line of certain radical being advised hollow copper conductor parallel connection replaces into a circle, or first the combinative structure parallel connection of little line rule hollow copper conductor with little line rule solid copper wire is replaced into a circle, being then wound into the fusiformis structure of multiturn, final grading is formed coil.
Technical solution of the present invention, principle and effect are remake and are described as follows:
If Fig. 1 is to shown in 7, a kind of air-gap armature motor, by core stamping 3, coil supports 4, coil 2 and groove contract 1 form, coil 2 is the fusiformis structure with cooling duct, jointly positioned by core stamping 3 and coil supports 4 and supported, as shown in Figure 4, coil 2 comprises winding leads 21 and coil cooling pipe joint 22, coil 2 type of cooling is cold in liquid, cooling medium is deionized water or transformer oil, as embodiment 1, as shown in Figure 5 and Figure 6, coil 2 is in molding manufacturing process, in the foreign side first advised by little line, side's hollow copper conductor replaces into a circle, after be coiled into fusiformis multiturn, final grading is formed coil, transposition schematic diagram is as shown in Figure 7.
nullAs shown in Figure 2，Described core stamping 3 is the axial cirque structure with dovetail slot，As shown in Figure 3，Described coil supports 4 is along the axial isosceles trapezoid wedge-shaped bar of iron core，It is embedded in described dovetail slot，Material is not magnetic conduction、Non-conductive、Intensity is high and heat conductivility is excellent composite or the plastics of similar performance and porous material，During air gap armature assembles，First core stamping 3 is overlapped together vertically，Then coil supports 4 is squeezed into vertically in each dovetail slot of core stamping 3，In the design phase，The dovetail slot of coil supports 4 with core stamping 3 need to be carried out the design of tolerance fit，Ensure to coordinate 31 and 41 between coil supports 4 and core stamping 3、32 and 42、33 and 43 is interference fits，Use tooling device，Coil 2 is put in the not magnetic conduction teeth groove being made up of coil supports 4，After squeeze into groove contract 1 and overall VPI，Thus play fixed coil 2 and the effect of transmission moment，The electromagnetic force that coil 2 is suffered in the course of the work simultaneously will be born by carrying out the coil supports 4 that tight fit contacts with core stamping 3，And pass to core stamping 3 by Columba livia tail.
The principle of the present invention is: the little line of certain radical is advised hollow copper conductor and replaces into a circle, after be coiled into the fusiformis of multiturn, final grading is formed coil 2, before unwrapping wire circle 2, along iron core circumferencial direction, coil supports 4 is axially squeezed in the dovetail slot of each core stamping 3 along motor, owing to being tight fit between the dovetail slot of coil supports 4 and core stamping 3, so time coil supports 4 become an entirety with core stamping 3, then formed coil is put in dovetail slot, squeeze into the overall VPI of groove contract 1, thus play fixed coil and the effect of transmission moment, in this air-gap armature motor, coil supports 4 primarily serves fixed coil, the effect of transmission electromagnetic force, hollow copper conductor had both played the effect of conduction, play again the effect of cooling.
Above-described is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, it is also possible to make some deformation and improvement, these broadly fall into protection scope of the present invention.
