The embodiment being described with reference to the drawings is exemplary, it is intended to for explaining the utility model, and it is not intended that new to this practicality
The limitation of type.
The stator 10 of the electric moto used in compressor according to the utility model embodiment is described in detail below with reference to Fig. 1-Fig. 3.
As depicted in figs. 1 and 2, can be included according to the stator 10 of the utility model embodiment：Stator core 1, the and of winding 2
Three lead-out wires 3, stator core 1 includes multiple coiling teeth 11, as shown in figure 3, coiling tooth 11 is equipped with wire for coiling
Coiling nozzle 20 can by wire around being located on coiling tooth 11, wherein, wire can be enamel-covered wire.Two adjacent coiling teeth 11 it
Between limit winding slot 12, winding slot 12 has inner side notch 13, and the shape of each coiling tooth 11 is identical, each winding slot 12
Shape is identical.
Wherein, action of the coiling nozzle 20 in the coiling of inner side slot mouth 13 can be seen in Fig. 3, as coiling nozzle 20 is too wide, easily contact
To inner side notch 13, coiling nozzle 20 is too narrow and can cause the short life of coiling nozzle 20, influences to produce, while in the inside of coiling nozzle 20
The size in hole also has skill very much, too small easily to cause enamel-covered wire inside to wear, and causes line to be hindered, too big coiling can not accurate position
Put, cause coiling arrangement chaotic.
Thus, the wire maximum line footpath of winding 2 is D, and the width of inner side notch 13 is W, meets relation D+1.2mm≤W≤D+
2.5mm.Meet the winding 2 and winding slot 12 of above-mentioned relation formula, can effectively reduce diameter of wire, so as to be easier to realize winding 2
High copper factor.

It is connected with the tail end 23 with the coil 21 on coiling tooth 8a, is so sequentially connected, until the head end of the coil 21 on coiling tooth 2a
22 are connected with the tail end 23 of the coil 21 on coiling tooth 1a.
And for example, as shown in Fig. 2 the head end 22 of a coil 21 tail end 23 with next coil 21 in the counterclockwise direction
Connected and formation tie point 24.The head end 22 of coil 21 on coiling tooth 1a can be with the tail end 23 of the coil 21 on coiling tooth 2a
It is connected, the head end 22 of the coil 21 on coiling tooth 2a can be connected with the tail end 23 of the coil 21 on coiling tooth 3a, so successively
It is connected, until the head end 22 of the coil 21 on coiling tooth 9a is connected with the tail end 23 of the coil 21 on coiling tooth 1a.Such line,
Coiling nozzle 20 can have greater room, so as to reduce the fraction defective in winding process.
As illustrated in fig. 1 and 2, three lead-out wires 3 can enter with multiple circumferentially distributed tie points 24 successively according to its order
Row connection, specifically, multiple tie points 24 are circumferentially distributed, and are connected between the tie point 24 of two tie points 24 spaced apart same
One lead-out wire 3.Tie point 24 between coiling tooth 111a and 9a, the tie point 24 between coiling tooth 116a and 7a, and around
Tie point 24 between line tooth 113a and 4a is connected on same lead-out wire 3.The stator 10 being arranged such can improve motor
Manufacturing in winding process, while improve motor copper factor.
Wherein, the winding method of coil 21 also has a variety of, for example, coil 21 includes a wire, i.e., as shown in figure 3, line
Circle 21 is formed using a wire coiling；And for example, coil 21 include at least two and around wire, i.e., coil 21 is by a plurality of wire
Coiling forms side by side, and such motor can choose the suitable winding mode of coil 21 according to the actual requirements.
Thus, according to the stator 10 of the electric moto used in compressor of the utility model embodiment, the full rate of winding slot 12 can be improved,
Motor performance can be improved, but also line footpath can be reduced in the case of single coiling, in the case where inner side slot mouth 13 is constant,
