Linear motor and linear motor drive system

摘要

A linear motor is capable of miniaturization of a device, sharing of effective magnetic fluxes between the magnetic poles adjacent to each other, and decreasing a magnetic attractive force acting between a mover and an armature, and a linear motor drive system. The linear motor includes a mover, formed by lining up a plurality of pieces of permanent magnets or magnetic materials while inversing a magnetization direction thereof, and an armature. First and second magnetic pole teeth are disposed in such a way as to vertically tuck the permanent magnet or the magnetic material. A magnetic material links the first magnetic pole tooth to the second magnetic pole tooth, thereby forming a path for a magnetic flux, and windings are disposed on the first magnetic pole tooth and the second magnetic pole tooth, respectively. At least two units of the armatures are lined to be linked to each other.
