Abstract
The invention discloses a motor comprising a rotor and a stator having a plurality of teeth. The stator is formed by combining a first stator and a second stator disposed on the inner side of the first stator. The combination can be realized by heating one of the first stator and the second stator to be expanded and then cooling the same to be contracted to generate the combination force. According to the motor provided by the invention, the stators can be combined together by using the thermal expansion principle.
Description
Technical field
The present invention relates to motor, be specifically related to utilize the motor of expansion principle in conjunction with stator.
Background technology
Motor is the mechanical device that obtains revolving force from electric energy, comprises stator (stator) and rotor (rotor).Rotor and stator produce electromagnetic interaction, by the strength rotation acting between electric current mobile on magnetic field and coil.
On the stator core of stator, form multiple grooves.Metal wire winding groove, each metal wire is electrified with lead-in wire tie lines.The metal wire being wound around on groove adopts common canoe and hairpin-type canoe.
Common canoe is that relatively thin metal wire is twisted on groove.According to common canoe, can use strand count, under fast state, seldom there is skin effect, but between the multiple coils that are wound around because space waste occupation efficiency is low.
Hairpin-type canoe is by relatively thick metal wire insertion groove.According to hairpin-type canoe, the waste of can not having living space between coil, occupation efficiency can maximize, and impedance reduces and lifting power output.But, can not be suitable for strand count, while increasing frequency for running up, because increasing copper loss, skin effect lowers efficiency.
For coil winding, between tooth, need tooth opening.But because there is noise and/or vibration in tooth opening in the time that motor rotates.Dwindle tooth opening, noise and/vibration is few, but availability declines.

Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiment.The same member of reality in description and accompanying drawing is to represent with same symbol, no longer repeat specification.And explanation is time of the present invention, omits this explanation if aim of the present invention is thickened to illustrating of relevant known function or structure.The numeral that uses in the declarative procedure of this specification (as first, second etc.) be the distinguished symbol that a member and other member are distinguished.
Fig. 1 is the schematic diagram of the motor of one embodiment of the invention.
As shown in the figure, the motor 100 of one embodiment of the invention comprises stator 110,120(stator), be positioned at the inner side of stator 110,120 and the rotor of rotation (rotor).
Stator 110,120 can form multiple steel plates by the shape of hairpin-type winding motor 100 form with drum lamination.Stator 110,120 comprises the first stator 110 and is incorporated into the second stator 120 of the first stator 110 inner sides.In other words, the first stator 110, the second stator 120 are annular, and the first stator 110 inner sides of outer circumferential side can be in conjunction with the second stator 120.Marriage relation about the first stator 110, the second stator 120 can describe in detail in this part.
On the first stator 110, can be equipped with the groove 112 between multiple teeth 111 and tooth 111.On multiple teeth 111, be wound around respectively coil 130(coil).Coil 130 is hairpin-type forms, is formed on tooth 111 and is wound around form repeatedly.The groove 112 of the coil 130 being wound around on tooth 111 between can filling tooth 111.
The coil 130 being wound around on tooth 111 is wound in tooth 111 by tooth opening 115.That is to say, coil 130 is by tooth opening 115 insertion grooves 112, and the coil 130 of insertion groove 112 can form the form that is wound around tooth 111.For winding around 130 need to have tooth opening 115.But tooth opening 115 can cause noise in the time that motor 100 rotates.That is to say, when the discontinuous existence of tooth opening 115 and motor 100 rotate, from tooth opening 115, noise and/or vibrations can occur.The motor 100 of one embodiment of the invention is can seal tooth opening 115 after coil 130 is wound around, and can reduce to greatest extent the noise and/or the vibration that occur because of tooth opening 115.
Fig. 2 is the schematic diagram of the stator marriage relation of pictorial image 1 motor.
As shown in Fig. 2 (a), on the first stator 110 of the motor 100 of one embodiment of the invention, possessing multiple teeth 111.Between tooth 111, there is groove 112.Coil 130 is wound in tooth 111 after injecting groove 112 by the tooth opening 115 between tooth 111.
The second stator 120 is positioned at the inner side of the first stator 110.The first stator 110 can heating after coil 130 is wound around.After heating, the diameter of the first stator 110 becomes large.That is to say, add thermal expansion and big or small the change greatly of the first stator 110 entirety.It is large that the diameter of the first stator 110 becomes, and between the first stator 110 and the second stator 120, can be offset (OFFSET).
As shown in Fig. 2 (b), cooling the first stator 110 of the first stator 110 heating can revert to original size.The size of the first stator 110 is recovered, the reduced of the first stator 110, and the skew (OFFSET) existing between the second stator 120 can disappear.That is to say, the outer circumferential side of the second stator 120 can be in conjunction with the first stator 110.
The second stator 120 and the first stator 110 are in conjunction with preventing that tooth opening 115 from exposing.Even if, also can not there is not noise and/or vibration because of tooth opening 115 in the rotor of motor 110 thereupon.
Fig. 3 is the schematic diagram of the stator marriage relation of the motor machine of diagram another embodiment of the present invention.
As shown in the figure, the first stator 100 can be in the inner side combination of the second stator 120.
As shown in Fig. 3 (a), on the first stator 110, can possess multiple teeth 111 that direction is protruded laterally.On tooth 111, can be wound around coil 130.Coil 130 is wound around after injecting groove 112 by tooth opening 115 on tooth 111.
The second stator 120 can heat.The heating radius of the second stator 120 can strengthen.The radius of the second stator 120 strengthens, and between the first stator 110, the second stator 120, can be offset (OFFSET).
As shown in Fig. 3 (b), the radius of cooling second stator 120 of the second stator 120 of heating can reduce.The radius of the second stator 120 reduces the second stator 120 and the first stator 110 firm combining mutually.
Fig. 4 is the schematic diagram of the motor stator marriage relation of another another embodiment of diagram the present invention.
As shown in the figure, the motor 100 of another another embodiment of the present invention be the second stator 120 a part form material different from other parts.
On the second stator 120, can there is different material portion 140.Different material portion 140 can with tooth 1110 between space corresponding.Different material portion 140 can be made up of materials such as SUS.That is to say, form different material portion 140 with materials different from other parts such as permeabilities, and then reduce back electromotive force.
Above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in aforementioned each embodiment, or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the scope of technical scheme described in various embodiments of the present invention.
