Abstract
The utility model discloses a form-wound coil structure which comprises a leading wire end noise end, a non-leading wire end nose end, a lead, a lower-layer stator coil edge and an upper-layer stator coil edge, wherein the intermediate diameter of the leading wire end nose end is larger than that of the non-leading wire end noise end. The increasing of the winding external diameter of the leading wire end is realized by increasing the intermediate diameter of the leading wire end nose end, so that the distribution area of a leading wire end winding on the space is enlarged, the down wire connection work of the leading wire end winding can be facilitated, and the installation quality of the leading wire end winding is ensured, therefore, the winding end part shape and the winding quality of a whole electromotor are improved.
Description
Technical field
The utility model relates to a kind of form-wound coil structure, relates in particular to a kind of form-wound coil structure that is applied to low-pressure high-power motor.
Background technology
At present; The form-wound coil that uses in the low-pressure high-power motor, two straight lines of coil are placed on respectively in two stator slots when rolling off the production line, and one of them straight line is stator coil upper coil limit; Another straight line is stator coil inner coil limit; As shown in Figure 1, lead end nose 1 is highly the same with non-lead end nose 2, and left-right symmetric distributes.The number of turn of low-pressure high-power motor is few; Coil is thick; In stator coring groove, highly differ bigger under the both sides of form-wound coil, because the lead end nose 1 and non-lead end nose 2 height such as grade on form-wound coil both sides, the coil of lead end is spatially arranged anxiety; Cause the staff to carry out the lead end wiring operating difficulties that rolls off the production line, the lead end winding is of low quality.
The utility model content
The purpose of the utility model provides the not form-wound coil structure of height such as grade of a kind of lead end nose and non-lead end nose, can make things convenient for the staff to carry out the wiring operation, improves lead end winding quality.
The utility model adopts following technical proposals:
A kind of form-wound coil structure comprises lead end nose, non-lead end nose, lead-in wire, stator coil inner coil limit and stator coil upper coil limit, and the middle footpath of said lead end nose is greater than the middle footpath of non-lead end nose.
The middle footpath of said lead end nose than the big 10mm in middle footpath of non-lead end nose to 20mm.
The utility model is through increasing footpath in the lead end nose; The winding external diameter of realizing lead end increases; Therefore the winding of lead end layout area spatially increases; Help the following wiring work of lead end winding, can guarantee the installation quality of lead end winding, thereby improved whole motor winding overhang shape and winding quality.
Description of drawings
Fig. 1 is for having the structural representation of the form-wound coil that uses in the low-pressure high-power motor now;
Fig. 2 is the structural representation of the utility model.
Embodiment
As shown in Figure 2; The utility model comprises lead end nose 3, non-lead end nose 4, lead-in wire 5, stator coil upper coil limit 6 and stator coil inner coil limit 7; To 20mm, after the middle footpath of lead end nose 3 increased, it is big that the winding external diameter of lead end becomes than the big 10mm in middle footpath of non-lead end nose 4 in the middle footpath of lead end nose 3; Therefore the winding of lead end layout area spatially increases; Help the following wiring work of lead end winding, can guarantee the installation quality of lead end winding, thereby improved whole motor winding overhang shape and winding quality.
Claims (2)
1. a form-wound coil structure comprises lead end nose, non-lead end nose, lead-in wire, stator coil inner coil limit and stator coil upper coil limit, and it is characterized in that: the middle footpath of said lead end nose is greater than the middle footpath of non-lead end nose.
2. form-wound coil structure as claimed in claim 1 is characterized in that: the middle footpath of said lead end nose than the big 10mm in middle footpath of non-lead end nose to 20mm.
