如何克服兩相混合式步進電機在低速運轉時的振動和噪聲?

文章來源:步進電機  時間:2013-08-24 11:52:24瀏覽次數:2916

      步進電機低速轉動時振動和噪聲大是其固有的缺點,一般可采用以下方案來克服:
        A、如步進電機正好工作在共振區,可通過改變減速比提高步進電機運行速度。
       ?。?、采用帶有細分功能的驅動器,這是最常用的,最簡便的方法。因為細分型驅動器電機的相電流變流較半步型平緩。
       ?。?、換成步距角更小的步進電機,如三相或五相步進電機,或兩相細分型步進電機。
       ?。?、換成直流或交流伺服電機,幾乎可以完全克服震動和噪聲,但成本較高。
       ?。?、在電機軸上加磁性阻尼器,市場上已有這種產品,但機械結構改變較大。
