Embodiment
Below, with reference to accompanying drawing, the present invention is more fully illustrated, shown in the drawings of exemplary embodiment of the present invention.But the present invention can be presented as multiple multi-form, and should not be construed as the exemplary embodiment being confined to describe here.But, these embodiments are provided, thus make the present invention comprehensively with complete, and scope of the present invention is fully conveyed to those of ordinary skill in the art.
For ease of illustrating, here can use such as " on ", the space relative terms such as D score " left side " " right side ", for illustration of the element of shown in figure or the feature relation relative to another element or feature.It should be understood that except the orientation shown in figure, spatial terminology is intended to comprise device different azimuth in use or operation.Such as, if the device in figure is squeezed, be stated as the element being positioned at other elements or feature D score will be positioned at other elements or feature " on ".Therefore, exemplary term D score can comprise upper and lower both orientation.Device can otherwise be located (90-degree rotation or be positioned at other orientation), and space used here illustrates relatively can correspondingly explain.
As shown in Figure 1 and Figure 2, the structure of the utility model washing motor comprises external stator 1, center rotor 2, magnetic pole 3, winding 4, some even number of poles 3 are circumferentially distributed on external stator 1, the polarity of magnetic pole 3 is along radial setting unshakable in one's determination, the polarity of adjacent pole is contrary, center rotor 2 comprises iron core and winding, around its axis radially several axial pass troughs 21 uniform on outer surface unshakable in one's determination, is provided with winding 4 in groove 21; The width of groove 21 is not more than folded circumferential width unshakable in one's determination between two adjacent grooves 21, and the gap between two adjacent poles 3 is not more than folded circumferential width unshakable in one's determination between two adjacent grooves; Winding 4 is stratified and set in groove 21 along radial direction unshakable in one's determination with layer of wires, winding 4 can by multiple conducting wires coiling, when adopting multiple conducting wires coiling, this multiple conducting wires is arranged in parallel successively, and be all arranged on same circular radial side face during coiling every layer winding, to ensure that every layer of winding is layer of wires; The section configuration of groove 21 is the rectangle of radial outer end opening, groove 21 two side is parallel to each other and its bottom surface and two side right angles, groove 21 two side and be provided with insulating barrier 5 between winding conducting wire in it, the winding 4 after coiling is fixed in groove 21 by resin (not shown).
After the section of groove 21 being arranged to the rectangle of band opening, effectively can ensure the layering coiling of the layer of wires of winding conducting wire in groove 21; Adopt layer of wires layering coiling, both can improve the utilance in space, reduce the volume of whole washing motor, effectively can reduce again the quantity of jumper and the length of jumper in winding, simplify the structure of winding; In addition, make folded circumferential width unshakable in one's determination between two grooves 21 be not less than the gap between two adjacent poles 3, effectively can ensure the cutting of winding center line circle to magnetic field magnetic line, ensure the operating efficiency of washing motor.
As shown in Figure 2, the wire 41 in every layer of winding is that often group comprises one group of wire of multiple conducting wires, at this moment in order to ensure that every layer of winding is layer of wires and needs each wire in one group of wire will along stalk to sequential.When adopting one group of wire coiling winding, first can be connected in series or parallel to each wire in group as required, and then export after serial or parallel connection is carried out in the termination of each wire.When wire initiating terminal participates in the coiling of winding, and after making the coil aperture direction in the winding of its coiling contrary with the coil aperture direction of wire end coiling, the coil crossover line being positioned at axially outside in every layer of winding can be made to be staggered, so not only facilitate the coiling of winding, also can improve the utilance in space, and also contribute to the heat radiation of winding after the arranging density of reduction wire.In addition, wire initiating terminal, tail end interlock after coiling winding, also need not arrange jumper, simplify winding construction, reduce unnecessary the taking in space.
Spindle iron core also can be divided into several sections by its round angle by the utility model washing motor, then the winding that coiling is relatively independent respectively on each section, the winding method of each section of winding is same as shown in Figure 2, it is to be noted, same when adopting one or one group of wire coiling every section of whole winding when segmentation coiling, due to wire end can not along iron core revolve turn around after naturally get back to wire initiating terminal, therefore wire end and its initiating terminal is needed to put on an equal footing, and take mode as hereinbefore to process, when both wire end being back wound around, the coil in its winding be wound around must be made overlapping with in the coil radial direction in ground floor winding.After iron core is pressed the multiple winding of round angle subsection setup, as required each winding can be exported separately, or export after carrying out suitable serial or parallel connection.
As shown in Fig. 3, Fig. 4, Fig. 5, center rotor 2 is also provided with dissipating cover 6, this dissipating cover 6 is provided with installing hole 7, blade 8 and air vent hole 9, dissipating cover 8 directly forms blade 8 and air vent hole 9 by mechanical stamping, dissipating cover 8 is followed center rotor rotation and is sucked cold wind by blade 8 and air vent hole 9, effectively lower the temperature, washing motor is run safely, for a long time.
