Abstract
The utility model relates to a fan stator which comprises a stator winding and a stator core, wherein the stator core is a tooth form stator core formed by multiple tooth form structure silicon steel plates uniformly distributed on an outer ring periphery through folding; an inserting winding groove is formed between adjacent two tooth forms of the tooth form stator core, and an insulating base is poured outside the stator core; the insulating base comprises left and right base bodies located on the axial two ends of the stator core and a groove inner insulation layer connected with the left and right base bodies, and the outer ring peripheries of the left and right base bodies can form a tooth form structure the size of which is matched with the shape of the stator core; and the groove inner insulation layer is pasted in the inserting winding groove of the stator core so as to form an insulated wire groove. The insulation base is poured outside the stator core provided by the utility model so as to form an integrated structure, the assembly is free, the insulativity is good and the shape is beautiful, the groove inner insulation layer is formed in the inserting winding groove so as to form the insulated wire groove, the rolling manufacture of the stator winding is convenient, and the defects that the original stator core requires that insulation paper is inserted in the inserting winding groove so as to bring inconvenience and the insulation paper is easy to shift and damage so as to cause unreliable insulativity are solved.
Description
Technical field
The utility model relates to fan, is specifically related to the stator on the fan.
Background technology
Fan stator is one of vitals that drive fan is rotated in the fan; Its Main Function is to produce rotating magnetic field.Fan stator generally includes stator winding, stator core and insulating base, the profile of tooth stator core of stator core for being built up by a plurality of silicon steel sheets, and profile of tooth stator core outer forms line embedding groove; The two ends that existing fan stator adopts left and right insulating base frame to be fastened on stator core form the profile of tooth stator assembly, and namely insulating base frame outer in the left and right sides is with the tooth-shape structure identical with stator core, and the stator winding winding is on stator assembly; Under such structure, left and right insulating base frame forms the two ends insulation to stator core, for guaranteeing to insulate between stator winding and the stator core, then need in the line embedding groove of stator core to fill up in addition to establish the suitable insulating paper of size, because line embedding groove is the U-shaped structure, need to be with the curling insertion of insulating paper, the defective of the poor insulativity that existence operation inconvenience and insulating paper displacement cause.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of employing stator core upper insulating base, and coiling is convenient, the fan stator of simple to operate and good insulating.
For achieving the above object, the utility model provides following technical scheme: a kind of fan stator, include stator winding and stator core, the profile of tooth stator core that described stator core builds up for the silicon steel sheet by a plurality of outer shroud Zhou Junbu tooth-shape structures, form line embedding groove between adjacent two profiles of tooth of profile of tooth stator core, it is characterized in that: described stator core is cast with insulating base outward, described insulating base comprises a left side that is positioned at the axial two ends of stator core, right pedestal and connection are left, the groove inner insulating layer of right pedestal, left, right pedestal outer shroud week forms the tooth-shape structure that adapts to the stator core shape size, and the groove inner insulating layer is sticked and forms the insulation wire casing in the line embedding groove of stator core.
By adopting technique scheme, the outer casting insulated seat of stator core forms integral structure, need not assembling, good insulating and good looking appearance, in the line embedding groove of stator core, form simultaneously insulation tank formation insulation wire casing in the groove, need not to insert in addition insulating paper, make things convenient for the coiling of stator winding and guaranteed that the insulation between stator winding and the stator core is reliable, solve former stator iron core and need insert insulating paper in line embedding groove, the breakage that easily is shifted of the inconvenience that brings and insulating paper causes the insecure defective of insulating properties.
The utility model further is set to: described stator core is provided with the orientation assemble hole vertically, and cast forms reference column in the orientation assemble hole of stator core, and reference column connects left and right pedestal.
By adopting technique scheme, it is more reliable that insulating base and stator core are fitted, and is connected firmly.
The utility model further is set to: offer two semicircle short slots that axially arrange along stator core on the inner circle hole wall of described stator core, two semicircle short slots are distributed on the inner circle hole wall of stator core relatively.
By adopting technique scheme, make things convenient for the location and installation of installation shaft.
Below in conjunction with accompanying drawing the utility model is further described.

Fig. 2 is the stator core construction schematic diagram of the utility model specific embodiment;
Fig. 3 is the insulating base frame structural representation of the utility model specific embodiment.
Embodiment
As Figure 1-3, the disclosed a kind of fan stator of the utility model, include stator winding and stator core 2, described stator core 2 is for to be built up by a plurality of silicon steel sheets, the outer shroud Zhou Junbu tooth-shape structure of silicon steel sheet, a plurality of silicon steel sheets build up rear formation profile of tooth stator core, form line embedding groove 20 between adjacent two profiles of tooth of profile of tooth stator core; Described stator core 2 is outer to be cast with insulating base 1, and described insulating base 1 comprises the left and right pedestal 10,11 that is positioned at stator core 2 axial two ends, connects left and right pedestal 10,11 groove inner insulating layer 12 and reference column 14; Described left and right pedestal 10,11 outer shrouds week form the tooth-shape structure that adapts to stator core 2 shape sizes, and groove inner insulating layer 12 is sticked at the line embedding groove 20 interior formation insulation wire casings 13 of stator core 2; Offer the orientation assemble hole 21 that arranges vertically at stator core 2, during cast, form reference column 14 in the 21 interior cast of the orientation assemble hole of stator core 2, reference column 14 connects left and right pedestal 10,11.Under the said structure, at stator core 2 upper insulating bases 1, fan stator forms insulation wire casing 13, has improved inconvenience and insecure defective that insulate that the conventional fan stator brings at line embedding groove 20 interior insertion insulating papers; Also made things convenient for simultaneously the coiling of stator winding, the stator winding winding only needs on stator core 2 time opening part at insulation wire casing 13 plug insulation scraps of paper to get final product, easy to operate, stator winding in the utility model and winding method thereof are routine techniques well known to those of ordinary skill in the art, so be that improved stator core and insulating base representation is more directly perceived, stator winding does not draw among the figure.
In this specific embodiment, offer two semicircle short slot 21, two semicircle short slots 21 that axially arrange along stator core 2 on the inner circle hole wall of described stator core 2 and relatively be distributed on the inner circle hole wall of stator core 2.
