Abstract
There is provided a linear motor that can detect the displacement of a moving member or the inclination of the moving member in a direction in which two windings are opposed to each other and equipment equipped with the linear motor. A linear motor includes: a first armature having an upper winding and a lower winding opposed to the upper winding through a gap in a vertical direction; a moving member having a permanent magnet and enabled to reciprocate in a longitudinal direction with respect to the first armature; and a current detecting unit that detects an electric current carried through the first armature. The upper winding and the lower winding are in parallel connection.
