The invention has the advantages of reducing the volume of the motor, lowering the difficulty of the production process and also enhancing the effect of radiation, and can be widely applied to the direct current motor.
Description
Technical field
The present invention relates to a kind of DC motor, relate 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.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of variable-blade wind power generation DC motor.
Purpose of the present invention will be achieved by the following technical programs:

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, beneficial effect of the present invention is: 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, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
