Abstract
The utility model discloses a silicon sheet structure used for a stator of a motor, including a hollow cylindrical base and a plurality of silicon sheets projecting from the external surface of the base uniformly according to a presetting interval, the head end of each silicon sheet is provided with a flange, the back end of each silicon sheet is arranged on the external surface of the base by a presetting steepness relative to the axial cord of the base, the lower side and the upper of the silicon sheets are staggered inversely, such that tapered slots based on the axial cord are formed between the flanges of two neighboring silicon sheets. The utility model is capable of weakening teeth harmonic electric potential and reducing resistant torquemoment caused by slot effect, so as to reduce effectively startup resistance moment of a permanent magnetism wind power generator to implement low speed power generation, the winding coils are arranged in a 'S' shape along the tapered slot, output power is stable, and service lifetime is long.
Description
Technical field
The utility model relates to motor technology, relates in particular to a kind of silicon steel structure that is used for motor stator.
Background technology
The stator of motor is the critical piece that constitutes motor, and it is made of silicon steel structure and the coil windings that is wrapped on the described silicon steel structure usually.Shown in Fig. 1-4, in the silicon steel structure of prior art, each silicon steel sheet 20 extends outward from the outer surface of pedestal 10 in perpendicular equably, and each silicon steel sheet 20 has a flange 30, the straight trough 40 of formation and parallel axes between the adjacent silicon steel sheet flange 30.
The shortcoming of this structure is that the slot ripples electromotive force is bigger, and slot effect causes bigger resistive torque, makes that the resistance of start square of generator is too big.
The utility model content
Technical problem to be solved in the utility model is: a kind of silicon steel structure that is used for motor stator is provided, this structure can weaken the slot ripples electromotive force, reduce the resistive torque that slot effect causes, thereby effectively reduce permanent-magnetic wind driven generator starting reactance square, the generating of realization low speed, winding coil is along the S-shaped arrangement of skewed slot, and power output is stable, long service life.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of silicon steel structure that is used for motor stator, include the cylindric pedestal of hollow and a plurality of outer surface from described pedestal according to the default silicon steel sheet that extends outward evenly and at intervals, the head end of each silicon steel sheet all has flange, the tail end of described each silicon steel sheet becomes a default gradient to arrange with axis on the outer surface of described pedestal, and the downside of described silicon steel sheet and upside also oppositely stagger, and make the skewed slot that correspondingly forms between the adjacent silicon steel sheet flange based on described axis.
The beneficial effects of the utility model are:
Embodiment of the present utility model is by being arranged to not consistent with axis skewed slot with the silicon steel film trap, to weaken the slot ripples electromotive force, to reduce the resistive torque that slot effect causes, thereby effectively reduce permanent-magnetic wind driven generator starting reactance square, realized the low speed generating, winding coil can be along the S-shaped arrangement of skewed slot, and power output is stable, long service life.
Below in conjunction with accompanying drawing the utility model is described in further detail.

Embodiment
Describe an embodiment of the silicon steel structure that is used for motor stator that the utility model provides in detail below with reference to Fig. 5-Fig. 8.
As shown in the figure, present embodiment mainly includes the cylindric pedestal 1 of hollow and a plurality of outer surface from pedestal 1 according to the default silicon steel sheet that extends outward evenly and at intervals 2, the head end of each silicon steel sheet 2 all has flange 3, and the tail end of each silicon steel sheet 2 becomes a default gradient to arrange with axis on the outer surface of pedestal 1, and the downside of described silicon steel sheet 2 and upside make the skewed slot 4 that correspondingly forms between the adjacent silicon steel sheet flange 3 based on described axis oppositely to stagger.
During specific implementation, the gradient of described skewed slot 4 is preferably the slot pitch between adjacent two silicon steel sheets.
In addition, the inner surface of pedestal 1 also is distributed with the semi-cylindrical recesses that plays the role of positioning 11 of four symmetries.
The above is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection range of the present utility model.
