Abstract

PURPOSE:To improve the starting torque and the efficiency of a DC linear motor and to produce smooth thrust by using a field magnet as a movable element and an armature formed of armature coil group as a stator. CONSTITUTION:A field magnet in which N- and S-poles are alternately provided is arranged in a movable magnetic yoke 7 to form a movable element, which is composed movably along a base 1 via drive rollers 8. An armature which has armature coil 3 group wound so that the opening angles of conductor units 3a, 3b which contribute to the thrust become integer times of the pole width of the field magnet is used as a stator. Further, a position detector is opposed to the field magnet at the armature side.
