Provided is a linear motor capable of preventing an increase in length of the armature in the moving direction and also of reducing cogging. The linear motor has a magnetic field part having a plurality of permanent magnets arranged in a straight line in such a manner that N poles and S poles are formed alternately; and an armature having a core which has a plurality of teeth arranged opposite to the magnetic field part with a gap created therebetween and a plurality of coils wound on the teeth of the core. Among the teeth with the coils wound around, a width TW1 in a relative moving direction of each of teeth placed at both ends in the relative moving direction of the armature is smaller, from a base part to an end part thereof, than a width TW2 in the relative moving direction of each of other teeth. |
