Description

The variable-blade wind power generation DC motor
Technical field
The utility model relates to a kind of DC motor, relates in particular to the stator of a kind of variable-blade wind power generation with DC motor.
Background technology
As shown in Figure 1, in the prior art, variable-blade wind power generation generally comprises stator and rotor with DC motor, described stator comprises casing 2 and is arranged on stator core 1, stator winding in the casing 2, stator core 1 comprises main iron core 11 spaced apart and commutation stage iron core 12, and described stator winding comprises main winding 111, commutating-pole winding 121 and the compensation winding 112 that is arranged on the stator core 1.
Yet in actual applications, main pole iron core 11 adopts steel plate to laminate, commutating pole iron core 12 adopts forged steel structures, and steel chassis becomes the part of magnetic circuit as yoke and since the magnetic conductivity of steel plate a little less than, cause motor magnetic circuit magnetic resistance to strengthen, need to improve the motor magnetic potential, increase the volume of motor; Because main pole iron core 11 in the stator and commutating pole iron core 12 need to install respectively, cause the defective of process consistency difference again, simultaneously, motor easily generates heat, the defective of temperature rise because motor only by casing 2 heat radiations, causes.
The utility model content
In view of the defective that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of variable-blade wind power generation DC motor.
The purpose of this utility model will be achieved by the following technical programs:
A kind of variable-blade wind power generation DC motor, comprise stator and rotor, described stator comprises casing and is arranged on described casing interior stator core, stator winding, described stator core comprises main iron core spaced apart and commutation stage iron core, described stator winding comprises main winding, commutating-pole winding and the compensation winding that is arranged on the described stator core, the integrated manufacturing of described stator core, described commutating-pole winding is arranged on the inboard of described main winding, and described compensation winding is arranged between the described main winding.
Further, the silicon steel plate stacking moulding of described stator core for becoming by the punch press punching.
Further, described casing is the aluminum casing that has radiating ribs.
Compared with prior art, the beneficial effects of the utility model are: the stator magnetic circuit that the stator core that (1) forms by silicon steel plate stacking replaces main pole iron core, commutating pole iron core and yoke (steel chassis) to form, the magnetic conductivity of silicon steel sheet is better than general steel plate greatly, magnetic resistance reduces, efficient improves, and can effectively reduce motor volume in design; (2) the stator core accuracy of manufacture is guaranteed by punch die, gets rid of human factor, has improved reliability; (3) adopt the aluminum casing of being with radiating ribs, increased area of dissipation, improved radiating effect.
Following constipation closes the embodiment accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
Description of drawings
Fig. 1 is the structural representation of the stator of prior art DC motor;
Fig. 2 is the structural representation of the utility model variable-blade wind power generation with the stator of DC motor.
Among the figure:
1 stator core, 11 main pole iron cores, 111 main pole windings
112 compensation windings, 12 commutating pole iron cores, 121 commutating-pole windings
2 casings
Embodiment
As shown in Figure 2, the utility model variable-blade wind power generation comprises stator and rotor with DC motor, described stator comprises casing 2 and is arranged on stator core 1, stator winding in the casing 2, casing 2 is for having the aluminum casing of radiating ribs, thereby improved area of dissipation and the radiating effect of described variable-blade wind power generation with DC motor, the silicon steel plate stacking moulding of stator core 1 for becoming by the punch press punching, because the magnetic conductivity of silicon steel sheet is better than general steel plate greatly, thereby make magnetic resistance reduce, efficient improves, and has effectively reduced the volume of motor; Stator core 1 comprises main iron core 11 spaced apart and commutation stage iron core 12, and described stator winding comprises main winding 111, commutating-pole winding 121 and the compensation winding 112 that is arranged on the stator core 1; Stator core 1 integrated manufacturing, thus make its accuracy of manufacture guarantee by punch die, get rid of human factor, improved reliability, commutating-pole winding 121 is arranged on the inboard of main winding 111, and compensation winding 112 is arranged between the main winding 111.
The utility model still has multiple concrete execution mode.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
