Linear motor and method of producing the same

A method of producing a linear motor which includes an armature and an element having a magnet,

• wherein said armature or said element having a magnet is movable, and said armature has a coil,
• first and second magnetic pole teeth are magnetically coupled to one magnetic pole of said armature and disposed in first and second stages, respectively, which are vertically arranged with respect to a moving direction of said armature or said element having a magnet,
• third and fourth magnetic pole teeth are magnetically coupled to an other magnetic pole of said armature and disposed in said first and second stages respectively,
• said first and second magnetic pole teeth are disposed alternately along the moving direction of said armature or said element having a magnet,
• said third and fourth magnetic pole teeth are disposed alternately along the moving direction of said armature or said element having a magnet, and
• said first and fourth magnetic pole teeth are disposed so as to substantially oppose one another, and said second and third magnetic pole teeth are disposed so as to substantially oppose one another,
• said method comprising the steps of:
• producing a plurality of armature core bodies divided in a vertical direction with respect to the moving direction of said armature or said element having a magnet;
• containing a winding of said armature in part of a core;
• and
• assembling said divided armature core bodies and said winding.
