<p>Provided is a highly responsive linear motor that can be constructed by reducing the weight of a mover. In order to attain this object, the linear motor includes a secondary side (a mover 30) in which magnets 3 and ladder-shaped members 4 of a magnetic material are arranged in alternate manner in a rectilinearly moving direction of the mover 30, the ladder-shaped members 4 each holding one of the magnets 3; and a primary side (a stator 201) that includes magnetic pole pieces 1 arranged in close proximity to the secondary side from above and below in a direction perpendicular to the rectilinearly moving direction with a common coil 2 wound around each of the magnetic pole pieces 1, the primary side including a magnetic material core 11 interconnecting the magnetic pole pieces 1; wherein the ladder-shaped members 4 of a magnetic material are formed with grooves 5.</p> |
