国内外轨道式机械爬楼装置的研究现状

对于老年人和行动不便的人来说,室内、室外的各种楼梯已经成为了他们参与社会生活的障碍。针对这一现状,产生了许多爬楼装置。其中轨道式机械爬楼装置是在楼梯上安装轨道,使装置沿轨道实现上下楼的运动。这一形式在国外应用很广。根据楼梯形状的不同,轨道有弯轨和直轨之分。导轨形状多样,与之配合的驱动导引机构也各具特色。这里介绍部分轨道式机械爬楼装置的特点、发展现状及其应用。

Properties of Brushless DC Machine Induced by Permanent Magnets Applied to a Traction Drive

The paper presents a mathematical model ofbrushless DC machine induced by permanent magnets. Its construction uses the classical model of permanent magnet synchronous machine and induced model of power inverter using the serraphil form. The results of the computer simulation were presented for such states： startup, work under active constant load and the behavior of the machine in terms of exponential and stepping change of the power inverter＇s control angle.
