Abstract
A linear motor may comprise a first member including a plurality of amature modules; and a second member including a permanent magnet module that includes a plurality of permanent magnets, of which the poles are alternated in a first direction along which the plurality of amature modules are arranged, wherein each armature module includes a magnet core including a connection part, and two or more salient poles protruding from the connection part, and a coil carrying a current of the same phase and wound around the magnetic core; wherein the permanent magnet module is disposed between two salient poles of the amature module; and wherein a distance between two neighboring armature modules is larger than a distance between two neighboring salient poles within the same amateur module.

A linear linear motor comprising:
- a first member including a plurality of amature modules;
- and
- a second member including a permanent magnet module that includes a plurality of permanent magnets, of which the poles are alternated in a first direction along which the plurality of amature modules are arranged,
- wherein one of the first member or the second member becomes a mover, and the other becomes a stator moving relative to each other in the first direction;
- wherein each armature module includes a magnet core including a connection part, and two or more salient poles protruding from the connection part, and a coil carrying a current of the same phase and wound around the magnetic core;
- wherein the permanent magnet module is disposed between two salient poles of the amature module;
- and
- wherein a distance between two neighboring armature modules is larger than a distance between two neighboring salient poles within the same amateur module.
