低价不影响压电机的性能

传统的压电机尽管有着良好的特性,但价格过高限制了它的广泛应用,这一点将发生改变。微技术公司Elliptec (多特蒙德,德国) CEO Bjrn Magnussen.表示,采用新的技术能够降低压电机的生产成本而不牺牲其性能。其电机在恶劣环境下,甚至强磁场中,仍能精确运转,这引起了医疗设备OEM制造商的极大兴趣。

设计的不受磁场影响的无噪音压电机用于医疗设备。

Elliptec是Siemens AG的分立公司,正是其在自动推进领域中压电技术的运用促进了Elliptecmotor的发展。“西门子以较低的成本,用压电技术设计燃料喷射器”,Magnussen说,“我们将其进一步深化。” 通过非研磨处理压电材料、降低复杂性及减少电子元件的数量等一系列创新方法,公司能大大隆低成本。

电机中整合了在电压作用下可振荡的压电元件。获专利技术的定子将振荡转化成其顶部的椭圆形运动。当定子顶部推向一个物体即产生微步运动。当运转频率从85变为95KHz时,运动方向将发生改变。

“此电机非常精确,在10m内,可立即加速和停止,而没有任何反冲力。” Magnussen说,“它小而轻,可用于便携式装置,耐受恶劣环境。它可在流体或真空中工作,强磁场对其也无影响。另外,它没有噪音。”

目前,一些医疗技术公司正在使用此产品,其他公司对其也有兴趣,但由于保密协议,他不能透露细节,Magnussen表示。
