Abstract
This disclosure discloses a linear motor including a stator, a mover, and a plurality of teeth. The stator includes a stator curved part having an arc shape in a longitudinal direction. The mover is arranged facing the stator and is moved in the longitudinal direction of the stator. The plurality of teeth are arranged in parallel along the longitudinal direction so that a pitch of the teeth at an outer-peripheral side is larger than the pitch of the teeth at an inner-peripheral side on the stator curved part.
