Abstract
The utility model relates to a motor stator with double concentric windings, which belongs to the technical field of motors, and aims at reducing cost. The motor stator comprises a stator core and a plurality of stator windings embedded in an inner ring of the stator core. The motor stator is characterized in that each stator winding is provided with two winding coils; and the two winding coils in the same stator winding are different from each other in size and pitch, and are embedded in a concentric way. The motor stator provided by the utility model can reduce the cost of a motor while guaranteeing the performance of the motor.
Description
Technical field
The utility model relates to motor technology, particularly relates to a kind of two with one heart technology of winding type motor stator.
Background technology
At present, have the stator winding of a lot of motors all to adopt Concentrical winding, Concentrical winding is coil similar by several shapes but that vary in size, becomes the coil groups of Back Word shape by same center setting-in.Winding can consist of according to different wire laying modes biplane or three plane windings with one heart.The stator winding of the threephase asynchronous of general single-phase motor and part small-power or large span coil adopts this pattern.
As shown in Figure 2, the Concentrical winding of conventional motors stator, all adopt four concentric setting-ins of (or three) coil to become the Back Word shape, the defective of this Concentrical winding is, because the coil quantity in the winding is more, therefore the pitch of each coil is all longer, and the copper consumption of each coil is also higher, so that the motor stator cost of traditional Concentrical winding is also always high.
The utility model content
For the defective that exists in the above-mentioned prior art, technical problem to be solved in the utility model provides the low two with one heart winding type motor stators of a kind of cost.
In order to solve the problems of the technologies described above, a kind of two with one heart winding type motor stators provided by the utility model comprise stator core, and are embedded at a plurality of stator winding of stator core inner ring that it is characterized in that: each stator winding all has two winding coils;
Size and the pitch of two winding coils in the same stator winding are different, and embed with one heart.
Further, the pitch of two winding coils in the same stator winding differs 2 line embedding grooves.
Two with one heart winding type motor stators that the utility model provides, because each stator winding is only formed by two concentric setting-ins of winding coil, what therefore the pitch of each coil can design is shorter, can save the coil copper consumption, namely guaranteed the properties of product requirement, the copper consumption of separate unit motor has been saved more than 6%, thereby reduced the motor stator cost of Concentrical winding.
Description of drawings
Fig. 1 is two with one heart stator winding expanded views of winding type motor stator of the utility model embodiment;
Fig. 2 is the stator winding expanded view of existing concentric winding type motor stator.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model is described in further detail, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection range of the present utility model in.
As shown in Figure 1, a kind of two with one heart winding type motor stators that the utility model embodiment provides comprise stator core, and are embedded at a plurality of stator winding of stator core inner ring that it is characterized in that: each stator winding all has two winding coils;
Size and the pitch of two winding coils in the same stator winding are different, and embed with one heart, consist of two Concentrical winding structures.
Among the utility model embodiment, described stator core inner ring is provided with 36 line embedding grooves, described stator winding has 18, the pitch of two winding coils in the same stator winding differs 2 line embedding grooves, the pitch of short-chord winding coil wherein is 4 line embedding grooves, and the pitch of long-chord winding coil wherein is 6 line embedding grooves.
Two Concentrical winding structures also are applicable to the motor stator of non-36 grooves among the utility model embodiment.
The utility model embodiment can make the copper consumption of separate unit motor save more than 6%.
Claims (2)
