馬達鐵芯模具

以往的鐵芯都是使用單沖模具或者連續(xù)模具沖壓制成散片，然后又通過鉚釘或者焊接的工藝，制作成所需要的厚度--鐵芯的材質一般采用硅鋼材料，單片的厚度有0.5mm、0.35mm、0.2mm等，這種工藝效率不高，使用人員也較多，因此逐漸被自動疊鉚鐵芯模具所替代，在這里我就著重介紹一下自動疊鉚鐵芯模具的情況。　自動疊鉚鐵芯模具采用多工位級進方式，模具上安裝有氣缸、鉚接沖頭、穿片沖頭、壓入沖頭、整形環(huán)等部件，通過沖壓機控制面板設定所需疊鉚片數，給電磁閥信號，然后由電磁閥帶動氣缸運行，氣缸控制鉚接沖頭和穿片沖頭壓入的深度來達到鉚接與分片的作用，從而疊鉚出不同厚度的鐵芯。　根據不同電機的性能要求，還可以利用步進馬達和渦輪渦桿控制下模刀口旋轉，達到轉子扭矩（斜槽）的效果。2100433B

鐵芯（磁芯）在整個馬達里面起到了舉足輕重的作用，它用來增加電感線圈的磁通量，已實現電磁功率的最大轉換。馬達鐵芯通常是由一個定子和一個轉子組合而成。定子通常作為不轉動的部分，而轉子通常是內嵌在定子的內部位置。

馬達鐵芯的應用范圍非常廣泛，步進電機，交直流電機，減速電機，外轉子電機，罩極電機，同步異步電機等都有比較廣泛的利用。

對于成品馬達來說，馬達鐵芯在電機配件里面起到的作用比較關鍵。要想讓一個電機的整體性能得到提高，就需要提升馬達鐵芯的性能。通常這種性能可以采用改善鐵芯沖片的材質，調整其材質的導磁率，控制好鐵損的大小等方式來解決。一個好的馬達鐵芯需要由精密的五金沖壓模具，采用自動鉚接的工藝，然后利用高精密度沖壓機臺沖壓出來。這樣做的好處是，可以最大程度地保證其產品的平面的完整度，最大程度地保證其產品精度。

通常品質優(yōu)良的馬達鐵芯就是利用此種工藝專業(yè)進行馬達鐵芯沖壓的。高精密度的五金連續(xù)沖壓模搭配高速度沖壓機，再加上優(yōu)秀的專業(yè)馬達鐵芯生產人員，才能最大程度地保證好的馬達鐵芯的出品率。

馬達鐵芯, The English named " motor core ", as the key parts in the motor, it's one of the most important part and has the great contribution in each motor. Usually , one motor core contain one rotor plus one stator. The stator as the not moving parts in the motor, but the rotor usually stay inside of the stator and running fast during the motor has the power.

Motor core widely used in step motor, universal motor, reduction gear motor, external rotor motor, shaded pole motor, induction motor.

For a fully motor, motor core is the very important thing in each motor. So if you want to improve the totally motor performance, it should do some hard work on the motor core. Usually we can change the material type of motor core, adjust the silicon steel's magnetism rate, control the right core loss of the silicon steel to make sure the motor has better performance. Normally one precision motor core need the high precision hardware tooling use the interlocking way, plus the high speed press machine to stamping it. By this way, it's more convenience to make sure the motor core's surface integrity, One precision motor core can ensure the motor has the better quality.

Basically the good performance motor core use the above process to stamping it. The highly precision hardware tooling plus the high speed press machine, use the excellence engineer and conscientious worker, to make sure each motor core has the better performance when come out.2100433B
