ABSTRACT:
A linear motor that comprises: a stator constituting a running track and having a longitudinal direction; a movable body disposed on the stator and being linearly movable along said longitudinal direction of the stator; an end detection sensor for detecting a state that the movable body is positioned at around an end of the stator; a drive circuit for driving the movable body to move on the stator; a control circuit for controlling the drive circuit and outputting a drive signal to the drive circuit to move and stop the movable body; and an overrun prevention circuit for preventing the movable body from overrunning out of the stator. The overrun prevention circuit is connected from said end detection sensor.
