Linear motor

A linear motor comprising:

• a stator including a stator yoke extending in a motor running direction and a plurality of permanent magnets arranged on the stator yoke at regular intervals along the motor running direction in alternately reversed directions to produce alternating polarities;
• and
• a moving part positioned generally parallel to the permanent magnets of the stator and separated therefrom by a specific gap, the moving part including a plurality of magnetic teeth arranged side by side along the motor running direction and coils wound around the individual magnetic teeth;
• wherein each of the magnetic teeth has a yoke portion located opposite to a side facing the stator, the yoke portion of each magnetic tooth being held in contact with the yoke portion of each adjoining magnetic tooth, and a tooth portion around which the coil is wound, the tooth portion extending from the yoke portion toward the stator;
• and
• wherein a pair of projecting parts is formed on end surfaces of the yoke portions of the individual magnetic teeth opposite to their side facing the stator, whereby gaps between the projecting parts form a groovelike channel running through the yoke portions of the successive magnetic teeth, and the multiple magnetic teeth are joined together into a single structure by fitting a connecting member in the groovelike channel.
