Abstract
The utility model discloses an insulation spacer between motor stator windings. The insulation spacer comprises insulation sheets used for isolating the windings at two ends of a stator and a connection strip used for connecting the insulation sheets, wherein the connection strip is clamped in a groove of an inner circular wall of the stator, and the insulation sheets are inserted in slits between the windings. Through technology provided by the insulation spacer, a problem of unguaranteed insulation property between windings of a stator in the prior art is solved, labor cost is saved, and motor reliability is improved.
Description
Technical field
The utility model relates to the insulating protection field between the motor winding, the particularly insulating spacer between a kind of motor stator winding.
Background technology
Motor mainly is comprised of stator and rotor two parts, and stator mainly contains stator core, stator winding, fixed base three parts compositions.Stator core is formed by stacking by the silicon steel sheet punching press, and integral body is sleeve-shaped, on the inner round wall of the iron core of stator, is uniform-distribution with groove, the stator winding that has coil to be coiled on stator core.
Stator winding is a kind of coil turned to by enamelled wire, the combination arranged together of a plurality of coil rules.Coil in winding embeds respectively in the groove of stator inner round wall according to certain rules, and the coil that stretches out groove is coiled into integral body at the stator both ends and is circular-arc coil combination.Can may cause short circuit between winding and winding because of the factor such as the improper use of the quality of circuit own, motor, environmental problem between winding and winding, burn out motor.The phase insulation in the stator core groove of technology in the past can't guarantee, the winding insulation of two ends of stator also can't guarantee.In prior art, separate on determinant both ends winding and winding insulation problem, the method for employing is: the insulating spacer of planting in the gap between winding and winding.But prior art has the following disadvantages: 1, in insulating spacer plant process, can stir winding, change the shape of winding; 2, insulating spacer out-of-shape, the outer end profile of partition need to be cut into the outer end profile of winding roughly the same, and needs manually to cut out after the assembling of this irregular partition, manually cuts out error larger, and having longly has shortly, between winding, can not effectively separate; 3, insulating spacer does not form a kind of effective fixing, and when motor uses, partition easily is shifted and just also can't guarantees to separate completely between such stator winding.Three aspect factor based on above-mentioned, between winding, insulating properties can not be guaranteed.
The utility model content
The purpose of this utility model is to provide the insulating spacer between a kind of motor stator winding to solve insulating reliability problem between winding.
For realizing above purpose, the technical solution adopted in the utility model is: comprise for separating stator two ends winding and the insulating trip of winding and the intercell connector that is connected insulating trip, the intercell connector holding is in the groove of stator inner round wall, and insulating trip is plugged in the gap between winding and winding.
Compared with prior art, there is following technique effect in the utility model: insulating spacer is stuck in the groove of stator inner round wall, assembling is simple, can not shine into large stirring to coil, thereby the insulating trip at two ends connects by intercell connector, holding can realize fixing in the groove of stator internal circular surfaces, the insulating trip shape is fixing without the artificial incomplete problem that separates between stator winding of having avoided of pruning, guarantee the insulating properties between winding, improved product reliability, reduced labour intensity.
The accompanying drawing explanation
Fig. 1 is the plane graph of insulating spacer;
Fig. 2 is the field frame assembly schematic cross-section.
Embodiment
Below in conjunction with Fig. 1, Fig. 2, utility model is done further deciphering:
Insulating spacer between motor stator winding, insulating spacer comprises for separating stator two ends winding and the insulating trip 10,20 of winding and the intercell connector 30 that is connected insulating trip 10,20, the groove of stator inner round wall setting is comprised of notch, groove shoulder, groove top semicircle, integral body is that notch is narrow, groove is takeed on to groove top semicircle and become gradually large state, coil is walked around intercell connector 30 holdings of rear partition in the groove of stator inner round wall, the meeting of intercell connector arranges width according to the width of rebate setting of groove, to reach when intercell connector 30 snaps onto in draw-in groove, is unlikely to drop.In the gap that insulating trip 10,20 is plugged between winding and winding.
Further, the peripheral profile of insulating trip 10,20 comprises arcuation limit 11,21 and straight flange 12,22, straight flange 12,22 is connected with intercell connector 30 with the limit of stretching out after the stator faces laminating, described insulating trip 10,20 integral body are semicircle or the semiellipse shape is arranged, adopt the benefit of this kind of structure to be: the winding outline line integral body of stator faces is semicircle or ellipse, insulating trip just can form a kind of isolation effectively to winding, prevents that coil from because of partition shape problem, mutual touching occurring; The straight portion of partition is connected with intercell connector with the stator faces laminating section of stretching out, and intercell connector is stuck in groove, and fixing of groove intercell connector just realized to fixing insulating trip.Stator two ends winding when installing around, described straight flange 12,20 divided long one section with the stator faces laminating, have so enough large insulation 10,20 and coiling formation to fit, and a shorter part is stretched out stator faces and is connected with intercell connector 30.
Further, because the coiling profile of stator faces winding is basic identical, the identical two ends that are oppositely disposed in intercell connector 30 of insulating trip 10,20.
Insulating spacer is generally selected the preimpregnation of DMD(epoxy in manufacturing process) material or DND (polyester film insulating paper softness is compound) material, this insulated with material is good, and material is not yielding, and the useful life of material is longer.
During installation, shown in Fig. 2, insulating spacer is along the stator sleeve direction, intercell connector on insulating spacer is snapped in groove, to better implement the present invention, smear one deck insulating cement after motor stator assembling, in the gap that the insulating trip of partition is partly planted between winding and winding on groove.
This kind of insulating spacer can be used industrialization to produce fully on a large scale, produces and the partition of stator around work size coupling, can enhance productivity significantly, improves stator insulating reliability around between work.
