摘要： There is provided a linear motor, having an armature and a needle with magnetism, in which the armature has at least a magnetic pole of a first polarity having a first opposed part and another magnetic pole of a second polarity having a second opposed part; the needle is held by the first opposed part, and is further held by the second opposed part; and a distribution of magnetism of the needle according to a position in the movable direction thereof. In this way, a leak of a magnetic flux from pole teeth passing between the pole teeth of the armature is decreased to increase a thrust and braking force of the needle, which is thereby enabled to generate a greater or smaller thrust in a specific section or sections than the thrust during usual linear movement.
