In addition, in the central part office of base 212, exist to project upwards the hub portion 213 that strengthens base rigidity.This hub portion 213 has through hole in the center, has located the rotating shaft (not shown) at this through hole place, for example, and the rotating shaft of washing machine.Described rotating shaft is connected with the connector (not shown) with hub portion 213.Therefore, along with rotor 200 rotations, the revolving force of rotor is sent to rotating shaft.
In addition, hub portion 213 has the fixing hole 214 that is used for connector is fixed to it, and the location hole 215 that perhaps is used for alignment connector is so that alignment connector at first.
The present invention has portrayed the motor that uses the aluminum heart yearn.Aluminum ratio copper well known in the art has bigger internal driving.Therefore, in order to reduce internal driving, comparing with traditional copper coil need the increase external diameter.
Equally, aluminium well known in the art has the ductility lower than copper, and is easy to be destroyed by external impact.Equally, aluminium is easy to be subjected to the particularly influence of salt solution of water, can cause the aluminum steel corrosion so that contact with salt solution.
Therefore, in motor of the present invention, preferably the aluminum coil have double the outside that is applied to the aluminum heart yearn coated film to be used for strengthening the intensity and the ductility of aluminum coil.The result of twice coated film is that the insulating reliability of coil is further strengthened.
As mentioned above, coil stops at tap terminal 128 or 129 places.Preferably overhang makes coated film be removed so that exposed heart yearn is used for being electrically connected.Therefore, as mentioned above, the overhang with exposed heart yearn is easy to destroyed owing to weak intensity and ductility.
Therefore, the invention discloses the insulated part that is used for overhang, the intensity that it has strengthened coil has prevented corrosion and insulation is provided.Describe described insulated part in detail with reference to Fig. 3 to 7.
Fig. 3 is tap terminal and the decomposition diagram that is arranged in the magmate in the tap terminal, and Fig. 4 is the assembling perspective view that is arranged in the overhang in the tap terminal, so that by described magmate overhang is connected to the tap terminal.
The tap terminal can be that power supply connects tap terminal 128 or neutral point tap terminal 129.But purpose has for convenience only been described neutral point, and one of ordinary skill in the art will appreciate that following description can be applied to power supply in the same manner and connect tap terminal 128.
Referring to Fig. 3 and 4, the tap terminal has the space 161 that is formed on wherein and is used for arranging therein described magmate150.Together with these, on the front and back in space, have groove 162, be used for the end of hold-in winding.The upper corners of preferred geosyncline 162 be cut sth. askew 163 or circular, to be convenient in groove 162, arranging coil.
Simultaneously, the insulator rib of describing before a side of tap terminal is connected to 123.
Referring to Fig. 3, described magmate150 has with each of back in front
The groove of shape.The consistency of thickness of the width of preferred geosyncline 151 and the iron core of coil.In other words, preferably the iron core of coil is engaged in the groove 151 so that be electrically connected to described magmate150.Therefore, described magmate need be formed by electric conducting material.
As mentioned above, when finding overhang in the groove 162 at the tap terminal, set up the electrical connection between described magmate150 and the overhang.Described magmate150 is arranged in the space 161 of tap terminal, and its heart yearn exposes.
Fig. 4 has illustrated that end winding and described magmate150 are disposed in the tap terminal to form the situation of neutral terminal 129.
Fig. 5 and 6 usefulness schematically illustrate the electrical connection between described magmate150 and the end winding.
When the heart yearn 162 of coil contacted with conduction magmate150, the end of described magmate150 and coil 160 was electrically connected to each other.Preferably has the insulated part that forms thereon at the part place that the heart yearn 162 of coil contacts with described magmate150.An example of such insulated part is the resin 170 that applies on described heart yearn 162 and magmate150 shown in Figure 6.Well-known magmate is the flexible magnets that is used in the electrical applications.
Therefore described resin 170 is insulating material, resin 170 is set keeping the insulation of described heart yearn 162 after coating, and protects described heart yearn 162 not to be subjected to ectocine.Insulation 170 has shielded the external pressure that directly is sent on the heart yearn 162, and the result has strengthened the intensity of heart yearn 162.
Fig. 7 has illustrated the resin 170 that spreads all over the coating of tap terminal.In other words, resin 170 be coated in not only that described magmate150 goes up and the exposed part of the heart yearn 162 of coil on, and be coated on the part of the coil 160 of not removing coated film therefrom.
Describe another embodiment of described insulated part in detail with reference to Fig. 8.
In the foregoing embodiments, be used for the exposed part of described heart yearn enhancing, insulate and the insulated part that prevents to corrode comprises the resin coating.
In this embodiment of the present invention, insulated part can comprise resin.But even resin is removed, this embodiment makes described insulated part have aforesaid function.
The coil slip of describing in detail according to a preferred embodiment of the present invention with reference to Figure 10 and 11 prevents structure.
Usually, coil being wrapped in the T type protruding on 112, is not directly thereon, but on the winding part 121 or 131 of the insulator on each T type protrudes.
In addition, coil is not a winding of single layer, but multilayer.For example, under the situation of the motor that is used for washing machine, coil can twine 4 layers.Therefore, the whole height of desirable winding layer will be 4 times of external diameter of coil.But if slide at the coil of lower floor, the coil in cover layer will be pressed, and perhaps on the contrary, protrude.Therefore, the coil of this protrusion makes the whole height of winding layer uprise, and allows during operation the infringement to the coil of described protrusion.
Therefore, preferably the protrusion of coil is minimized, and the slip that this is prevented coil is very important.
According to the length of winding part and the external diameter of coil, the maximum number that can be wrapped in the number of turn of the coil on winding part 121 or 131 is fixed.For example, if the length L of winding part is 20mm, and the external diameter of coil is 0.95mm, and the possible number of the number of turn is 20.
In Figure 10, show one type the winding of making by this method with reference number 200.
And, each of the clearing end of the initiating terminal of winding part and winding part, just, each of the opposed end of winding part has the gap.This gap is less than the external diameter of coil.Therefore, the coil that is wrapped on the gap pushes the coil of other windings, with the gap between forming, is not the opposed end of winding part, but at the coil of other parts of winding part, has caused defective winding.
Therefore, what prevent the coil slip is very important, need fill the gap at the opposed end place of winding part for this reason.
For this reason, utilize additional winding 210 and 211 that a circle is forced to increase to be used for preventing the slip of coil in each gap.
In other words, winding is from coil 201 and coil 202, up to coil 203 and coil 204, and then on T.In this case, as mentioned above, for example, 21 circles have been made.
But the present invention proposes to utilize coil 210 and 211 to cover additional circle there forcibly.Coil 210 and 211 is filled in the gap at the place, opposite end of winding part respectively.According to so, because coil self is recessed, they have prevented the generation of sliding.
Preferably a Fu Jia circle is formed on opposite side that twines initial part and the opposite side that twines the part that finishes.In other words, from coil 201 to coil 202 1/2 circle and from coil 204 to coil 211 1/2 circle is forced to increase to force to increase a circle.
Simultaneously, twine formation first coil layer by such pressure.Then, because formed the winding path of next coil layer, also prevented the slip of coil at the cover layer place by the coil in first coil layer.In other words, because coil has circular portion, formed fixed path between adjacent windings, along this path, coil is twined again.Simultaneously, as mentioned above,, and prevented subsiding of coil layer even also prevented slip on such path owing to coil twines.
Together with these, preferably only in ground floor, form an additional circle, rather than the layer on ground floor.In other words, because an additional circle protrudes than other coil height, if twine once more at projection, the coil of locating in the opposite end of winding part will protrude highly than other coils.
The insulated part of motor is according to a second embodiment of the present invention described with reference to Fig. 8 and 9.
Fig. 8 is the perspective view of the tap terminal cap 180 of explanation conduct insulated part according to a second embodiment of the present invention.
Tap terminal cap 180 covers tap terminal top and goes up to receive the tap terminal.In other words, tap terminal cap 180 fully covers the outside of tap terminal so that the insulation of tap terminal.
Therefore, although there is the exposed part of heart yearn 162, exposed part also only appears at tap terminal inside, so that the tap terminal is insulated, and the function that exposed part insulation that makes the tap terminal to carry out to make heart yearn and the exposed part that prevents heart yearn are corroded.
Tap terminal cap 180 among Fig. 8 can cover on the tap terminal of the coil that has the magmate150 that is arranged in wherein and have exposed heart yearn.In this case, the not part of the coil of exposed heart yearn that is positioned in the groove 162 is pushed by the bottom 181 of tap terminal.Therefore, external pressure directly is not sent to the exposed part of heart yearn, but only is sent to the coiler part that is positioned in the groove, has prevented the cutting of heart yearn part.
Equally, preferably tap terminal cap 180 covers the darker tap terminal of groove 162 of score tab terminals.In other words, preferably when the tap terminal cap covered the tap terminal fully, the bottom 181 of tap terminal cap was orientated the height of being scheduled to above groove 162 as, is used for stoping in advance water to pass groove 162 and enters wherein.
Referring to Fig. 8, tap terminal cap 180 can manufacture the isolated parts from described magmate150; And tap terminal cap 180 also can manufacture parts with described magmate150.In other words, described magmate150 is arranged in the tap terminal cap 180, and the tap terminal is arranged in the tap terminal cap 180, utilizes once-through operation to realize being electrically connected and in the formation of the insulated part at tap terminal place.
For example, though the tap terminal is formed by electric conducting material, the tap terminal cap can be formed by insulating material, and in other words, that selects from one group of resin is a kind of.Therefore, if in the injection mold of tap terminal cap the tap terminal is inserted into the tap terminal cap, tap terminal and tap terminal cover can manufacture parts.
Tap terminal cap 180 is used for making described magmate150 and its outside to insulate fully with the described magmate150 that insulate, and a problem that causes is that described magmate150 is difficult to be electrically connected to other parts except coil.Therefore, although preferably the tap terminal is applied to tap terminal cap 180 and neutral point tap terminal 129, those skilled in the art will also recognize that other mode.
With reference to the insulated part of Fig. 9 detailed description according to the 3rd preferred embodiment of the present invention.
Referring to Fig. 9, insulated part further comprises the enhancing part 239 of the intensity that is used for strengthening the tap terminal.
Strengthen the side that part 239 is formed on the tap terminal.Concrete, strengthen part and upwards be formed on its inside or outside in the footpath of tap terminal.But, consider the facility of an end of fixed coil, preferably strengthen part and upwards being formed on its outside in the footpath of tap terminal.As the tap terminal, preferably described enhancing part forms parts with insulator.
For the tap terminal, preferably strengthen part 239 and have groove 241.According to so, overhang is fixed to the groove 241 that strengthens in the part and the groove 162 in the tap terminal, has therefore further strengthened the stationarity of coil.
In addition, preferred geosyncline 241 or 162 has the width consistent with the external diameter of coil 160.Preferred geosyncline 241 or 162 width form the external diameter less than coil 160, have applied the film of certain limit on described coil, to such an extent as to coil is suitable for groove 241 and 162, and are fixed to the there equally.But more preferably width is within reason little of to prevent to have destroyed coated film.
The description of the width of described groove not only is applicable to this embodiment, and is applicable to aforesaid other embodiment.
Together with these, preferably strengthen part 239 and have the recess 240 that forms in the predetermined space in strengthening part 239.Preferably this recess is associated by the inside of groove 162 with the tap terminal.Therefore, coil 160 passes recess 240 and is fixed to the tap terminal.

In the present invention, because twine along the path between the adjacent windings, even formed four layer line circles, four times of the external diameter of the aspect ratio coil of coil layer are low.In other words, along with making that winding is tightr, can realize safer winding.
And, the invention discloses except being used to fill another kind of coil the structure of additional winding in the gap prevention structure of sliding at the place, opposite end of winding part.
Referring to Figure 11, the coil prevention structure of sliding can be the protrusion of projection that is used to reduce the length of winding part.In other words, protrude, preferably in the part and the part relative part place of twining end initial with winding in winding place, opposite end formation partly.The height that protrudes has reduced the length of winding part, and preferably forms protrusion according to the external diameter of coil and the length of winding part, so that do not form the gap between the coil that twines.
And, if greater than the external diameter of coil, may there be the situation of the winding that can't realize a circle in the length of protruding.Therefore, the length of preferably protruding is less than the external diameter of coil.
In addition, protrusion can be not projection on the length direction of winding part but diametrically.In other words, can form protrusion in the corner of winding opposite end partly.In this case, the protrusion length of preferably radially protruding is disturbed tectal winding less than the external diameter of coil to be used to prevent to protrude.
Therefore, it is identical with the prior art winding method to have a winding method of protrusion.But, protrude the slip prevented coil so that defective winding minimizes.
Need be when twining winding around so that minimize destruction, because used the aluminum coil to coil.In other words, preferably coil appropriateness is twined and is not had an abrupt bend.
For this reason, partly provide the coil supporting branch to winding.Figure 12 shows in Fig. 1 the cross section along line I-I, in other words, can be applied to the two the cross section of winding part of top insulator and lower isolator.
Winding around on winding part, coil is wound, the top of part from a side to winding, and once more from there to its side.In this case, coil from a side when twine on top, coil is easy to abrupt bend 90 degree.In this case, coil self is impaired, and exists because the decrease in efficiency that the impedance of the increase of the flip-flop generation of shape causes.
Therefore, preferably the winding part has the coil supporting branch on its top, twines so that coil is appropriate to be used to support described coil.
Simultaneously, the coil supporting branch can comprise from the opposite edges on the top first coil supporting branch protruding upward, and the second coil supporting branch between first coil supporting is divided.
Preferably the protrusion height of second coil supporting branch is greater than the protrusion height of first coil supporting branch.Utilize the coil supporting branch, coil can be supported, so that appropriate crooked isochrone circle forms a radian.
Preferably the second coil supporting branch has circular front end, is used to expand outside power to minimize the infringement to coil.It also is applicatory dividing this about first coil supporting.
The present invention allows the application of the coil of aluminum heart yearn.In addition, motor of the present invention comprises the insulated part that the enhancing, insulation and the slip that are used for the aluminum heart yearn prevents.
Concerning those skilled in the art, do not break away from spirit of the present invention or scope, can do various modifications and changes to the present invention.Therefore, the invention is intended to cover provide in the scope of accessory claim or their equivalent to modifications and variations of the present invention.
