Description
Technical field
The utility model relates to condenser type motor stator chip and rotor chip, relates in particular to a kind of stator chip and rotor chip that is applicable to family expenses or industrial small-power fan electromotor.
Background technology
Motor stator chip and rotor chip in the same industry all adopts a kind of more ready-made and general design always at present, because what considered when design originally mainly is its versatility, so compare certain products at some, seem more low as its performance on small-power, the slow-revving motor, waste of material is more.For example, the makers' standard specification of silicon steel sheet is that 1200mm is wide, and actual manufacture process high speed punching press meeting produces the waste material of certain width, and design originally is to manufacture the wide stator chip of 75mm * 15, and the wide waste material of then total 75mm produces.The rotor chip is that pairing is made, and promptly the rotor chip is to come out from the mesopore blanking punching press of stator chip, rather than other material, and the existing design of the external diameter of rotor chip is 44mm.
Summary of the invention
First purpose of the present utility model is at the stator chip that has universal design now when being applied to some special types, exist the low and more problem of waste material of performance, make full use of the limit on the electric machine theory, carry out Electromagnetic Design and calculation at special type, provide a kind of and can improve the effect ratio, reduce the fan condenser type motor stator chip of material cost.
Second purpose of the present utility model is to provide the rotor chip of stator chip pairing manufacturing a kind of and of the present utility model.
First purpose of the present utility model is achieved in that stator chip of the present utility model, which is provided with mesopore, main winding groove and auxiliary winding groove, and the length and width of described stator chip is of a size of 76.3mm ± 0.5mm.
Second purpose of the present utility model is achieved in that the external diameter of rotor chip of the present utility model is 51.5mm ± 0.5mm.
Technique effect of the present utility model is: the utility model technology compared to prior art at first consideration be the unnecessary waste that reduces material, make full use of the innovation of manufacturing technology, the length and width size of stator chip is increased to 76.3mm, so just equal to have increased the magnetic conductive area and the area of dissipation of stator chip, thereby improve the effect of motor, and waste material width altogether is reduced to 55.5mm, thereby improves the utilance of material; Secondly the utility model is to carry out Electromagnetic Design targetedly at the small-power fan with the characteristic of condenser type motor, does not consider its versatility, gives full play to the electromagnetic performance of material.By above improvement, raising motor properties that can be bigger reduces the waste of material, thereby reduces material cost, adopts motor of the present utility model can reach 15～2O% in the saving of copper cash under with the situation of performance grade.The utility model has the use advantage requiring rotating ratio lower (below 1500 rev/mins) relatively when starting torque is relatively large.
