The magnetic pole surfaces of every upper pole plate and every lower pole plate or the silicon steel plates can be made into the same length or different length and can be partially overlapped or mutually staggered; the terminal of the total magnetic pole surface combining the magnetic pole surfaces can be formed into the step shape or a sloped edge. The present invention can add the conducting effect of magnetic flux and further increase the rotary torque force of a rotor; the present invention has no rotary dead corner of the rotor and further facilitate the start-up of the rotor.
Description
Technical field
The present invention relates to a kind of motor stator group, referring in particular to a kind ofly increases magnetic flux conducting effect and can avoid rotating the dead angle, and then increases the stator pack structure of the motor that rotates torsion.
Background technology
See also Figure 11, shown in Figure 12, it is a kind of known stator pack structure, it is by central siphon 91 windings superior pole piece 92 to be arranged, members such as coil holder 93 and inferior pole piece 94, and this superior pole piece 92, inferior pole piece 94 respectively has the side wall 95 that extends to the bending of coil holder 93 directions, 96, the known stator pack of this kind, owing to have the side wall 95 of extension, 96, therefore, this superior pole piece 92, inferior pole piece 94 can be by the side wall 95 that extends, 96 form the annular permanent magnnet induction of big sensitive surface and rotor, but, on this kind structure, inferior pole piece is that each silicon steel sheet by a uniform thickness is bent to form, therefore extend the side wall 95 of bending, though 96 have strengthened sensitive surface, but on, the section thickness of the magnetism guiding access of inferior pole piece own does not still have increase, so magnetic flux conducting poor effect, and has the torsion deficiency of rotation and rotating speed still to have instability equally, the problem of floating.
Summary of the invention
Purpose of the present invention is to be to provide a kind of motor stator group, and it is to increase magnetic flux conducting effect, and then can increase the rotation torsion of rotor.
An of the present invention purpose is that a kind of motor stator group is being provided, and it is the rotation dead angle that does not have rotor, and then makes rotor be easy to starting.
The object of the present invention is achieved like this:
A kind of motor stator group includes:
Coil holder is wound with coil on it;
The superior pole piece group, form by the superior pole piece more than two and to be stacked and placed on coil holder top, this each superior pole piece is provided with a plurality of extreme, and each extreme vertical extent has magnetic pole strength by this, the magnetic pole strength of this each superior pole piece rotates on the magnetic pole strength of another superior pole piece relatively, so magnetic pole strength can select to form local overlapping or non-overlapped setting of staggering, to reach magnetic pole strength one by one around being distributed in around the coil holder and forming total magnetic pole strength of going up of superior pole piece group, to increase the permanent magnet of induction distribution area corresponding to rotor;
