Embodiment
See also appended graphicly, the utility model enumerated the following example explanation:
See also shown in Figure 2ly,, constituted by silicon steel sheet 1, accessory plate 2 for the utility model forms first preferred embodiment of stator pack.
Silicon steel sheet 1 is made identical shaped by magnetic conductive material, preferably stacked by doing more than at least two, and this silicon steel sheet 1 respectively has a dispensing hole 11 to pass through for central siphons to connect, and this silicon steel sheet 1 also is provided with setting element 13 such as several dispensing hole 12 supply and marketing with this silicon steel sheet 1 and accessory plate 2 combinations; Each silicon steel sheet 1 has several post arms 14 of radial, and forms magnetic pole strength 15 in these each post arm 14 terminals, and each magnetic pole strength 15 can be responded to mutually with the annular permanent magnnet of rotor.
Accessory plate 2 is made by magnetic conductive material, this accessory plate 2 has axis hole 21 and dispensing hole 22, the axis hole 11 of axis hole 21 and silicon steel sheet 1 matches to pass through for central siphon and connects, dispensing hole 22 matches with the dispensing hole 12 of silicon steel sheet 1, for setting element 13 with accessory plate 2 and silicon steel sheet 1 pass through connect fixing, accessory plate 2 has the post arm 23 that the post arm 14 with silicon steel sheet 1 matches, post arm 23 terminals form magnetic pole strength 24,2 of accessory plates are provided with auxiliary arm 25 between each post arm 23, auxiliary arm 25 terminals have the magnetic pole strength 26 that extends towards vertical direction, this magnetic pole strength 26 staggers mutually with the magnetic pole strength 15 of silicon steel sheet 1 and leaves spacing each other, and the magnetic pole strength 26 of this accessory plate 2 can form different in width or height with the magnetic pole strength 15 of silicon steel sheet 1.
See also shown in Figure 3, assembling situation for the utility model first preferred embodiment, respectively by the axis hole 11 of a plurality of silicon steel sheets 1 with this accessory plate 2,21 is involutory, and can be passed through by a central siphon and connect (figure does not illustrate), and by its dispensing hole that matches 12,22 supply setting element 13 that this silicon steel sheet 1 is combined with accessory plate 2, then with the post arm 14 of this silicon steel sheet 1 with accessory plate 2,23 winding arounds, so, formed stator pack, the magnetic pole strength 15 that this silicon steel sheet 1 and accessory plate 2 are superimposed, 24, stagger mutually with the auxiliary arm 25 set magnetic pole strengths 26 of accessory plate 2, and form different in width or thickness, therefore, the permanent magnet of this stator pack and rotor can have bigger induction area, make this rotor can have bigger rotation torsion, again and, because the magnetic pole strength 15 of this silicon steel sheet 1 and accessory plate 2,24, be formed with different in width or thickness with the auxiliary arm 25 set magnetic pole strengths 26 of accessory plate 2, therefore, nuclear-magnetism pole-face 15,24 with magnetic pole strength 26 can form the magnetic flux that does not wait, form unequal induction with the permanent magnet of rotor, so, can make rotor that the effect that is easy to start is arranged.Therefore, when the annular permanent magnnet of rotor was responded to it, this rotor can be easy to the starting rotation, did not have the rotation dead angle.
See also shown in Figure 4ly, be that the utility model forms second preferred embodiment of stator pack, it is made of silicon steel sheet 1, accessory plate 3.
This silicon steel sheet 1 is identical with first embodiment, in the middle of this preferred embodiment, this accessory plate 3 has axis hole 31, dispensing hole 32 and radial even number auxiliary arm 33, auxiliary arm 33 terminals have the magnetic pole strength 34 that extends towards vertical direction, the 15 one-tenth different in width of magnetic pole strength or the thickness of this magnetic pole strength 34 and silicon steel sheet 1.
In the middle of this preferred embodiment, several silicon steel sheets 1 are earlier stacked, again by post arm 14 winding arounds of these several silicon steel sheets 1, and then accessory plate 3 is combined with silicon steel sheet 1 with setting element 13, the stator pack of present embodiment and since accessory plate 3 not in conjunction with before, 15 of the magnetic pole strengths of this silicon steel sheet 1 have bigger spacing, therefore, in that do in the coiling work can be comparatively convenient.And after coiling work is finished, this silicon steel sheet 1 is formed with different in width or thickness with the auxiliary arm 33 set magnetic pole strengths 34 of accessory plate 3, therefore, this magnetic pole strength 15,34 also can form the magnetic flux that does not wait, form unequal induction with the permanent magnet of rotor, can make rotor that the effect that is easy to start is arranged.Therefore, when the annular permanent magnnet of rotor was responded to it, this rotor also can reach and be easy to the starting rotation.
Stator pack of the present utility model has the magnetic pole strength of different in width or thickness, and therefore, this magnetic pole strength and magnetic pole strength can form the magnetic flux that does not wait, and forms unequal induction with the permanent magnet of rotor.So, the effect that rotor is had be easy to start and do not have the rotation dead angle, again and, when doing coiling work earlier, owing to have big spacing between the magnetic pole strength of this silicon steel sheet by stacked silicon steel sheet.Therefore, this coiling work also can be easier to be done.
The utility model can not depart under the main design and feature, implements with other different form.Therefore, above-mentioned preferred embodiment just is listed by way of example, it should be considered as restriction of the present utility model.The various variations that are equal to according to design of the present utility model is done all should be included within design of the present utility model and the scope of patent protection.
