Embodiment
Below in conjunction with the drawings and specific embodiments, the structure of the stator module for centralized winding synchronous machine of the present utility model is formed, feature and operation principle be described in detail.For the substantive distinguishing features of stator module is described better, the part identical with prior art is only carried out brief description or is omitted.
In general, the utility model provides a kind of stator module for centralized winding synchronous machine, insulator spacer is provided with in the stator slot of this stator module, by the novel design feature of this separator, thus can by adjacent inductance loop seclusion, and by stator slot and iron core isolation, thus avoid the generation of electrical contact and arc phenomenon.
Particularly, as shown in Figure 1, be the structural representation of stator module of the present utility model; The insulator spacer structural representation in one embodiment for stator module of the present utility model as shown in Figure 2.With reference to accompanying drawing, stator module 100 for centralized winding synchronous machine 10 of the present utility model, comprise motor stator 110, multiple stator tooth 130 for being wound around for coil 120 is provided with in motor stator 110, and be limited with stator slot 140 between adjacent stator tooth 130, especially, insulator spacer 150 is provided with in each stator slot 140, composition graphs 2, insulator spacer 150 comprises base portion 151 and is arranged at two fins 152 of base portion side respectively, base portion 151 extends along the longitudinal axis of motor stator 110 in the stator slot 140 of correspondence, and two fins 152 are positioned at the outer end of corresponding stator slot 140.
When assembling, by base portion 151, insulator spacer 150 being inserted into stator slot 140 central authorities, thus stator slot being divided into two parts, to be separated by adjacent coil 120.Thus, even if when the consumption of coiling is very large, because do not allow between coil 120 to contact with each other, the insulation between winding thus be enhanced.
Further, two axial end of motor stator 110 are respectively arranged with thermoplastic insulated end cover 160, and thermoplastic insulated end cover 160 comprises the end cap perimembranous 161 of ring-type and the end cap teeth portion 162 corresponding with stator tooth 130.Insulator spacer 150 and thermoplastic insulated end cover 160 are used in conjunction with each other, especially, thermoplastic insulated end cover 160 makes coiling enter or the opening that exits groove is not just in the position of groove center, but remove certain distance from center, avoid to make coiling and the coil of himself contacting with contiguous coil, thus improve the insulating properties between coil further.
With reference to Fig. 3, preferably, base portion 151 is provided with recess 153, can be equipped with heat protector of motor (not shown) in recess 153.
In the execution mode shown in Fig. 2,3, the width of insulator spacer 150 equals the degree of depth of stator slot 140, to realize the abundant insulation isolation between coil.
Be provided with iron core (not shown) in motor stator 110, the stator slot 140 of correspondence and iron core are separated by two fins 152.By this fin 152 is inserted between stator slot and iron core, can insulating reliability be improved and avoid the generation that electric arc flashes.
In sum, stator module of the present utility model, by utilizing insulator spacer by contiguous inductance loop seclusion and utilizing the fin on separator stator slot and iron core spatially to be isolated, thus improve insulating reliability, avoid risk electric arc occurring and flashes, and do not need other extra insulating means.
Easy understand, the utility model is not limited to the concrete example that above-mentioned execution mode provides, and its any permutation and combination and apparent modification, all should fall in protection range of the present utility model.
