Abstract

See full text

A linear motor includes a plurality of magnets arranged at equal intervals, and an armature arranged opposite to the magnets and including an armature core having a plurality of teeth extending toward the magnets. The teeth include a first tooth located at one end in the thrust direction and a second tooth located at the other end on the opposite side. The first tooth and the second tooth have different dimensions or shapes so as to reduce cogging force generated due to the structure of the armature core at the ends in the thrust direction.
