摘要：
A linear motor includes a field including main-magnetic-pole permanent magnets magnetized in a direction of a generation magnetic field, and sub-magnetic-pole permanent magnets magnetized in a direction different from the direction of magnetic poles of the main-magnetic-pole permanent magnets, portions of the main-magnetic-pole permanent magnets located at a magnetic-field generation side being replaced with soft magnetic materials; and an armature including an armature core having teeth and armature coils wound around the armature cores. The linear motor satisfies λ
