Summary of the invention
It is the stator coil that the lower concave part of recessed setting forms that the utility model provides a kind of outer invalid edges by relatively strafing lug boss that limit raises up with relative limit of strafing, and the superimposed limit of strafing of coil that makes of coil that can be circular arc with inside and outside invalid edges is in phase co-altitude; Solve the production technology existed in prior art comparatively complicated, production efficiency is low, and magnetic utilance is lower, the technical problem of the little grade of moment of torsion.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of stator coil, comprise the coil body closed circlewise, coil body to be strafed in limit invalid edges and outer invalid edges in outer end formed by the limit and being fixedly connected on strafed of a pair contour setting, it is characterized in that: described outer invalid edges includes relatively strafes the lug boss that limit raises up and strafe with relative the lower concave part that limit is recessed setting, described lug boss and lower concave part are linked in sequence along strafing the circumferential of limit, and the lug boss thickness strafing limit protruding or recessed height be all more than or equal to outer invalid edges self relative to lower concave part.By the outer invalid edges of coil is arranged to relatively strafe the recessed lug boss of limit epirelief and lower concave part, therefore, recessed and coil that is epirelief can be respectively with outer invalid edges to be formed and coordinate, make to strafe limit after superimposed and be in identical height, multiple coil is superimposed together formation coil windings, thus stator encapsulate time more for convenience, production efficiency is high, because the limit of strafing of the coil after superimposed is in identical height, strafing limit has the distance of the rotor upper magnetic steel of the left and right sides to be all identical, thus magnetic utilance is higher, and the Motor torque made is larger.
As preferably, described lug boss and lower concave part are circular arc.Lug boss and lower concave part are all set to circular arc, make the extrusion modling of coil more for convenience, not easy damaged during coils press.
As preferably, the height of projection of described lug boss is identical setting with the recessed degree of depth of lower concave part.Therefore, when other coil and the utility model is superimposed use time, only need the superimposed use of a kind of coil that the recessed degree of depth is identical with the height of projection of lug boss, be conducive to reducing accessory kind, reduction production cost.
As preferably, the shape of described interior invalid edges is identical setting with the shape of outer invalid edges.When the power of motor is larger, then corresponding coil windings is also comparatively large, therefore, then need the shape of invalid edges in coil to be arranged to the shape of outer invalid edges be identical, thus when ensureing that coil is superimposed, the limit of strafing of coil remains on identical height.
Therefore, the utility model has following characteristics compared to existing technology: by the outer invalid edges of coil is arranged to relatively strafe the recessed lug boss of limit epirelief and lower concave part, recessed and coil that is epirelief can be respectively with outer invalid edges to be formed and coordinate, make to strafe limit after superimposed and be in identical height, encapsulation is convenient, production efficiency is high, and magnetic utilance is higher, and the Motor torque made is larger.
