Less conductive wire cross-section excellentPut and be, it makes it possible to wind the line quickly and realized higher copper filling rate.
According to another preferred embodiment, the sub-winding of at least two in lower floor and upper strataIn each groove, there is different conductive wire cross-section, so that sub-winding has identical resistance.But this angle from process technology is disadvantageous, because must store and process notSame diameter of wire.
According to the embodiment of a modification of the present invention, the coil of the first and second sub-windingsSide lays respectively at identical in the groove of advancing extremely down. That is to say, the first groove is along rotationDirection comprise simultaneously below sub-winding and the sub-winding of top, the sub-winding of described below andThe sub-winding parallel ground of top is connected with commutator thin slice. This has advantages of commutation, its asFollowing advantageously generation effect.
According to another preferred embodiment, armature body has 14 grooves, and wherein armature is usedIn four utmost point motors. Owing to being provided with 14 grooves, in the armature of four utmost points, produce as 14/4=3.5Slot pitch. Different from apart from width by the sub-winding of below and the sub-winding of top, underAdvance out under extremely successively at this in the sub-winding of side and the second coil side of the sub-winding of topCome, realized thus less cogging torque.
In order to improve the filling rate in groove, sub-winding preferably can have minimum and be about 0.2The conductive wire cross-section of mm.
In order to realize the as far as possible little structure space with high efficiency motor, winding is preferredBe made of copper and not made of aluminum.
Described object also realizes by a kind of manufacture method, and the first sub-winding is logical respectively for this reasonCross flying trident coiling technology in the bottom of groove around tooth with than the second sub-winding large 1 around apart from instituteStating the second sub-winding top reels. Can be very economical and quick by means of flying trident coiling technologyThe electricity with multiple windings and very thin circuit blank (Leitungsverschnitten) is realized on groundPivot. On the contrary, in the time that conductive wire cross-section is larger, would rather use pin type coiling technology.
The present invention also realizes by means of a kind of motor, and this motor configuration is, first of belowSub-winding have than the second sub-winding at least large 1 of top around distance. Thus, two sons aroundGroup has the Ohmic resistance of approximate formed objects, makes sub-winding below, that be positioned at inner sideCan not bear higher thermic load than the sub-winding of top.
Also feasible, the winding of top have than the winding of below higher around distance. But,Herein, resistance ratio has in two sub-windings that identical even difference is more around distance in the situation thatGreatly, and the sub-winding that is positioned at trench bottom can carry larger electric current, therefore causes bearing moreHigh heat load. Therefore, this embodiment is not preferred.
It should be understood that the above-mentioned and following feature that also will describe can not only be with phaseThe applied in any combination that should provide, and can also apply with other combination.
