Description
Technical field
The utility model belongs to motor field, and in particular to a kind of slotless wedge-type motor stator and its motor, generator.
Background technique
Motor stator, especially generator stator of vehicle generally will use slot wedge when coil is embedded in stator core to consolidate
Alignment circle prevents coil in the radial direction movement of stator core and for the insulation between coil and stator core.Which is made
Copper wire copper factor at stator is relatively low (slot wedge occupies the space of slot, reduces the copper wire that can be accommodated), increases iron core
Iron loss also hinders the heat dissipation of copper wire.
Utility model content
The purpose of the utility model is to provide a kind of slotless wedge-type motor stator and its motor, generator, this is practical new
Type eliminates slot wedge, reduces the iron loss of stator core, improves copper factor, will not stop magnetic field, improves dissipating for copper wire
Heat saves the use of material, saves installation steps.
The technical scheme adopted by the utility model is
A kind of slotless wedge-type motor stator, including stator core, insertion stator core wire casing in copper wire, be located at copper wire and
Insulated paint and insulating paper between stator core, copper wire are in single multi-tier arrangement in wire casing, are existed along the copper wire of innermost layer
More than at one and compression forms expansion section, and expansion section is wider than the opening of wire casing, and the copper wire of remainder layer is narrower than the opening of wire casing.
Preferably, expansion section applies certain pressure by pressure head on the copper wire of innermost layer makes the copper wire of innermost layer in pressure
Normal orientation, which is deformed, to expand, and pressure head end is narrow, rear portion is wide and passes through chamfered transition to rear portion by end.
Preferably, there are expansion sections at three along the copper wire of innermost layer, wherein respectively close to the both ends of stator core at two
Face is located in the middle part of stator core at third.
Preferably, copper wire is flat type copper wire.
A kind of motor, including slotless wedge-type motor stator as described above.
A kind of generator, including slotless wedge-type motor stator as described above.
Preferably, generator is automobile current generator.
The beneficial effects of the utility model are:
After being embedded in all layers of copper wire, expansion section is processed along the copper wire of innermost layer, expansion section is wider than the opening of wire casing,
In addition the insulated paint after further solidifying, copper wire will not moving radially along stator core again, in this way, then eliminate slot wedge,
Compared with traditional motor stator, the iron loss of stator core is reduced, copper factor is improved, magnetic field will not be stopped, improved
The heat dissipation of copper wire saves the use of material, saves installation steps.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of slotless wedge-type motor stator 7, including in stator core 8, insertion 8 wire casing 5 of stator core
Copper wire 3, insulated paint and insulating paper 4 between copper wire 3 and stator core 8, copper wire 3 are in single multi-tier arrangement in wire casing 5,
Existing along the copper wire 3 of innermost layer more than at one and is pressurized into expansion section 1, expansion section 1 is wider than the opening of wire casing 5, remaining
The copper wire 3 of layer is narrower than the opening of wire casing 5.After being embedded in all layers of copper wire 3, expansion section 1 is processed along the copper wire 3 of innermost layer,
Expansion section 1 is wider than the opening of wire casing 5, in addition the insulated paint after further solidifying, copper wire 3 will not be again along the diameter of stator core 8
To movement, in this way, then eliminating slot wedge 2, compared with traditional motor stator, the iron loss of stator core 8 is reduced, is improved
Copper factor will not stop magnetic field, improve the heat dissipation of copper wire 3, save the use of material, save installation steps.
As shown in Figures 1 to 4, in the present embodiment, expansion section 1 applies a level pressure on the copper wire 3 of innermost layer by pressure head 6
Power is deformed the copper wire 3 of innermost layer in the normal orientation of pressure to expand, the narrow rear portion in 6 end of pressure head it is wide and by end to
Rear portion passes through chamfered transition.
In the present embodiment, there are expansion sections 1 at three along the copper wire 3 of innermost layer, wherein respectively close to stator iron at two
The both ends of the surface of core 8 are located at 8 middle part of stator core at third.It is, of course, also possible to increase and decrease the number of expansion section 1 according to actual needs
And position, this not immobilizes.
As shown in Figure 1 and Figure 4, in the present embodiment, copper wire 3 is flat type copper wire, improves copper factor, and facilitate and to form expansion
Portion 1, naturally it is also possible to use circular copper wire.
The application of slotless wedge-type motor stator 7 is very extensive, can be sent out in the motor as shown in figure 5, can also be used in
In motor, such as automobile current generator.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
