Abstract
A linear motor includes a housing, a mover and a stator unit. The mover is movable relative to the housing, and includes a rod member, a plurality of first magnetic poles mounted to the rod member, and a plurality of second magnetic poles mounted to the rod member. The first and second magnetic poles are arranged alternately in a circumferential direction of the rod member, and are partially overlapped circumferentially. The stator unit is disposed in the housing, surrounds the mover, and is able to be energized to drive reciprocal movement of the mover relative to the housing.
