MOVING MAGNET TYPE LINEAR MOTOR FOR AUTOMATIC DOOR

摘要

In a moving magnet type linear motor for automatic door of the invention, a stator (10) fixed inside a guide rail (1) having a substantially INTERSECTION -shaped cross section and a moving unit (20) having a substantially U -shaped cross section are combined so that a height of the linear motor can be the same as that of the guide rail and the moving unit is supported slidably relative to the guide rail and fixing members of the stator has at least the both longitudinal ends or the stroke ends formed of non-magnetic conductive materials in order that the moving magnet type linear motor for automatic door produces only a low sound and is durable.
