轻巧有刷直流电机可提供高持续输出功率

专营微型和专业电机产品的一家公司为其有刷直流电机系列增添了35FLT电机新成员。美国丹纳赫传动下属公司Portescap(www.portescap.com; sales.asia@portescap.com)推出的这款电机符合RoHS标准,厚度为35mm,重360克,转矩据称比同类大小的标准铁芯电机高出40%。

该公司的有刷直流产品系列经理Udayan Senapati表示:“35GLT是集合了Portescap讲求创新的传统和在多层线圈有刷直流无芯电机设计方面的经验的成果。35GLT经过精密工程设计,将其在承载较高载荷时的速度变化减至最低。譬如48V线圈的电机在以100mNm持续转矩承载5mNm载荷波动时,速度变化只有4%。对于医学、宇航和电子组装领域而言,35GLT电机的此项独特设计提高了较大转矩下的驱动力。

35GLT电机的最大持续转矩接近150mNm,比同类的传统电机高出25%。35GLT电机共有5种绕组,电压范围介于24到90V之间,并可配合各种齿轮箱和编码器加以定制,以达最佳经济效益。

较大的持续转矩和输出功率,加上轻巧外观,能减轻使用者的负担和疲劳。这点对如电力手持工具的应用是非常重要的。该电机也适于需要维持较大持续转矩的应用,如进给与组装工具、自动座椅和医院病床等应用领域。

在要求更加严格的用途方面,如将高温处理作为一项先决条件的实验室自动化,35GLT电机据称比同类电机的环境散热量低(按焦耳测定),还可使用一种专利纤维包裹隔热技术来进一步减少散热。
