Title:
LINEAR MOTOR
Document Type and Number:
WIPO Patent Application WO/2010/140534
Kind Code:
A1
Abstract:
Provided is a linear motor, wherein the dimension of a base section of magnets can be suppressed from becoming larger, even when the dimension of the magnets, along a straight line that is perpendicular to the direction the magnets are lined up, and that is parallel to an opposing face of an armature-core facing the magnets, is made to be larger than the dimension of the armature-core along this straight line. The linear motor is provided with: a field system (1) that is equipped with the base section (3), and multiple magnets (4) lined-up on this base section (3); and an armature (2) that is equipped with the armature-core (5) that faces the magnets (4), and that moves along the direction in which the magnets (4) are lined up. The whole area of the opposing face of the armature-core (5) faces the magnets (4), when viewed along the direction in which the magnets (4) are lined up; and each of the magnets (4) adjacent to each other have the centers thereof deviate from the center of the armature-core (5), in mutually different directions; and mounting holes (3a) are formed on the base section (3), at areas located in directions opposite the deviating directions of the magnets (4), when viewed along a direction perpendicular to the opposing face (5a).
