The globality of every circle coil has been risen, and has further improved its insulation performance and wear-resisting property, so that motor effectively be avoided to open
When dynamic, coil is generated by electromagnetic force vibrates caused wearout.In the present embodiment, using polystyrene staple fiber
Non-woven textile carries out binding cladding to coil.
2, fill insulant between the out-phase coil of disposed adjacent, can be effectively isolated out of phase winding in this way, guarantee
Phase insulation in other embodiments, can also fill other insulating materials in this example using insulating paper.
3, across the two neighboring multiturn coil for embedding the wire groove groove wall end face by insulband binding and fixing, this makes neighbouring cloth
The multiturn coil set is bundled, so as to further promote the globality of End winding.
4, the periphery of ring winding overhang 10 is coated with end hoop 311, and end hoop 311 can tie the circumferential direction of winding overhang 10
It is strapped fixed, guarantee its circumferential stability.
Preferably, 311 adjacent stator iron cores 20 arrangement, the spacing of end hoop 311 and 20 end face of stator core are bound round in the end
Less than or equal to 30mm.The conducting wire drawn from stator core line embedding groove, base portion is linearly, then extends outwardly and is bent,
Drawn in another line embedding groove of access, or pulled out electric machine casing, end hoop 311 is located at 10 adjacent stator iron core 20 of winding overhang
Place, is avoided that conducting wire is lost under the action of mechanical oscillation or electromagnetic force, conducting wire is effectively ensured from straightway to curved section
Smooth transition, promoted winding overhang 10 globality.
End hoop 311 is made of the insulating materials with stickiness and elasticity, and in the present embodiment, end hoop 311, which uses, to be had
The insulating tape ring winding overhang 10 of stickiness and elasticity is bound, which is denoted as bandage 1, can be convenient for winding in this way
Adjustment of the conducting wire of end 10 in subsequent binding process, and it is avoided that end hoop 311 slips in subsequent process of binding
Lead to the situation that conducting wire is intractable.In the present embodiment, bandage 1 is using the netted nothing of epoxy resin impregnated glass fiber
Latitude binding strap.
Bandage 1 encloses and binds to form end hoop 311 along winding overhang 10 circumferentially around 6~10, and binding in this way is guaranteeing
While conducting wire is docile, also for the further shaping of conducting wire, there are fine tuning spaces.
5, intercoil connection 11, the harness annular in shape of lead-out wire 12 are fixed on the periphery of winding overhang 10.That is, intercoil connection
11, the shape of lead-out wire 12 is consistent with the shape of winding overhang 10.Preferably, 12 binding and fixing of lead-out wire are in winding overhang 10
At lateral surface, the intercoil connection 11 of arrangement annular in shape, lead-out wire 12 are away from 2~6mm of coil wire body.
Preferably, the internal diameter of whole winding overhang 10 annular in shape is greater than the internal diameter of stator core 20, outer diameter is less than stator
The outer diameter of iron core 20.
The mechanical strength and electrical apparatus insulation intensity for having greatly reinforced winding overhang 10 in this way, be both highly resistant to mechanical vibration
Destructive power caused by dynamic, electromagnetic force, moreover it is possible to electric insulation caused by corona, greasy dirt, air corrosion be avoided to fail.
In the present embodiment, using following technology for binding:
Step A: after embedding, shaping is carried out to the conducting wire of winding overhang 10, is close to end leads mutually, shape circle
Whole, the internal diameter of whole winding overhang 10 annular in shape is greater than the internal diameter of stator core 20, outer diameter is less than the outer diameter of stator core 20；
Step B: at 10 adjacent stator iron core 20 of winding overhang, with bandage 1 along winding overhang 10 circumferentially around extremely
Few 2 enclose and bind to form end hoop 311, carry out circumferential Primary Location to the conducting wire of winding overhang 10.
Specifically, in stepb, pretightning force when bandage 1 is bound is 8~15N, and bandage 1 is away from stator core
At 10 peripheral wall of winding overhang within the 30mm of end face, 6~10 circle of its circumference of ring winding forms end hoop 311.That is, bandage one
The end hoop 311 that circumferentially wound 6~10 circle of 31 ring winding overhangs 10 is formed is less than etc. with the spacing of 20 proximate end face of stator core
In 30mm.In the present embodiment, bandage 1 forms end hoop 311 circumferentially around 8 circle bindings along winding overhang 10.
Step C: being wrapped up comprehensively with every circle coil of 2 32 pairs of winding overhangs 10 of bandage, is made embedding positioned at stator core 20
The coil wire body of the external side of cable slot is tightened and is coated by bandage 2 32 completely.In the present embodiment, bandage 2 32 is using poly-
Styrene staple fiber non-woven textile.
Step D: the sky that bandage 3 33 is enclosed across the end face of stator core 20 and two adjacent strand circles
Gap, then binding and fixing keep the multiturn coil of disposed adjacent bundled, further promote End winding across the multiturn coil at this
Globality；The inside for being located at end hoop 311 with body of bandage 3 33, avoids bandage 3 33 from interfering with bandage 1, prevents
Under the action of mechanical oscillation and electromagnetic force fracture failure occurs for bandage one, 3 31,33.
What needs to be explained here is that " one coil " refers to penetrating or wearing from the same line embedding groove of stator core 20
All conducting wires out generally include at least two circle coils, and " two adjacent strand circles " are referred to across stator core 20 adjacent two
Two strand circles between a line embedding groove.
In step D, it should first be inserted into insulating paper 40 between adjacent out-phase coil, then carry out the binding of bandage 3 33,
It is effectively isolated out of phase winding, guarantees phase insulation；It, should be first when being bound to the winding overhang 10 for being located at leading-out terminal
Intercoil connection 11 and lead-out wire 12 are managed out along the circumferential direction of winding overhang 10, and make 12 binding and fixing of lead-out wire in winding overhang 10
At lateral surface.In the present embodiment, bandage 3 33 uses polystyrene staple fiber non-woven textile.
Step E: it will be tightened along the circumferential intercoil connection 11 managed out of winding overhang 10 and lead-out wire 12 with bandage 4 34 and to form one
A annular shape harness.
What needs to be explained here is that in other embodiments, bandage one, two, three, 4 31,32,33,34 can also use
Other insulbands.
