Abstract
The invention provides a kind of high copper factor motor stator adopting the trapezoidal enamelled wire of compacting.Load slot insulating paper in the groove of the stator core of this stator, slot insulating paper dresses up S shape in groove, and slot insulating paper is higher than the end face 3-5 millimeter of stator core, and S type insulating paper top is embedded with internal layer enamelled wire, and bottom is embedded with cover warnish envelope curve.It is ladder type shape that described internal layer enamelled wire and cover warnish envelope curve are all pressed into profile, and is bent into U-shaped shape.The copper factor of this motor stator can up to 82-90%, and under identical power conditions, motor is lightweight, and caloric value is little; Slot insulating paper adopts serpentine shape, and structure is simple, easy to loading and unloading.
Description
Technical field
The utility model relates to vehicle electric motor field, is related specifically to a kind of high copper factor motor stator adopting the trapezoidal enamelled wire of compacting.
Background technology
At present, its Stator Slots bit architecture of the electric motor of automobile of existing traditional form is complicated, its primary structure as shown in Figure 4, first insertion groove insulating paper 1a in stator core 7a, then embeds internal layer enamelled wire group 2a, cuts off with layer insulation paper 3a, embed cover warnish envelope curve group 4a again, load cover slot paper 5a, finally insert slot wedge 6a, this structure has following defect:
1, motor coil is artificial embedding, and labour intensity is large, and production efficiency is low, and is difficult to realize mechanical automation production;
2, coil of stator of motor copper factor is low, and all below 75%, motor operational efficiency is low;
3, stator coil end size is high, causes that motor volume is large, weight is large, cost is high.
Summary of the invention
The purpose of this utility model be to provide a kind of " S " type slot insulating paper replace conventional motors stator for interlayer, cover slot insulating paper, replace the employing of enamelled wire group to suppress the high copper factor motor stator of trapezoidal enamelled wire with heavy in section trapezoidal enamelled wire.
For achieving the above object, the technical solution of the utility model is:
A kind of high copper factor motor stator adopting the trapezoidal enamelled wire of compacting, comprise slot insulating paper, internal layer enamelled wire, cover warnish envelope curve and stator core, slot insulating paper is loaded in the groove of the stator core of this stator, slot insulating paper dresses up S shape in groove, and slot insulating paper is higher than the end face 3-5 millimeter of stator core, S type insulating paper top is embedded with internal layer enamelled wire, and bottom is embedded with cover warnish envelope curve, to ensure inside and outside layer enamelled wire mutually insulated and and stator core insulation.
Described internal layer enamelled wire and cover warnish envelope curve all adopt the enamelled wire of special paint film to be pressed into profile and iron core grooved and ladder type shape of the same size through mechanical means, be bent into U-shaped shape back and reverse 1 rule span, insert in order in stator core slot from stator core end, then carry out end to turn one's head, ectonexine rotates 1/2 front span respectively to rightabout; Finally weld enamelled wire end according to the order of connection with TIG realize the connection in series-parallel of coil and connect lead-out wire.
Good effect of the present utility model is:
1, enamel insulated round copper wire can be pressed into special equipment the ladder type shape matched with stator core grooved, can directly insert in stator slot after one-shot forming;
2, the copper factor of motor stator can up to 82-90%, and under identical power conditions, motor is lightweight, and caloric value is little;
3, slot insulating paper adopts serpentine shape, and structure is simple, easy to loading and unloading, uses special equipment one-shot forming, insertion;
4, utilize mechanical automation to produce, greatly reduce labour intensity, improve production efficiency.

Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing 1-3.
See Fig. 1-3, first slot insulating paper 1 being converted into serpentine shape inserts in the groove of stator core 4, then with special equipment intercepting corresponding length enamelled wire and divesting two ends paint film, be pressed into after being bent into " U " type and the grooved of stator core 4 and ladder type shape of the same size, two ends are reversed 1 rule span and are formed internal layer enamelled wire 2 and cover warnish envelope curve 3, the internal layer of stator core 4 groove and the skin of a rule span of being separated by is inserted again in order from stator core end, U-shaped line quantity is identical with the groove number of stator core 4, insert all U-shaped lines in order successively, then 1/2 span is reversed respectively round about in the end of all internal layer enamelled wires 2 and all cover warnish envelope curves 3, become stator coil 5, finally weld enamelled wire end according to the order of connection with TIG realize the connection in series-parallel of coil and connect lead-out wire.Thus the motor stator that formation one is complete.
