Abstract
A slider unit having built in a moving-coil linear motor ensuring high propulsion, is kept slim in overall height. A moving-coil assembly is made slim, with high stiffness, and is composed of an iron core of platy-configuration, and at least one set of three-phase armature coils wound around the iron core in the form of flat rectangular configuration in a plane intersecting the sliding direction. Comparatively more coil sides of the armature coils contribute to high propulsion. Like poles on either field magnet are placed in opposition to each other across the air gap, whereby the magnetic attraction is cancelled to reduce the load on the linear motion guide unit.
