ABSTRACT:
A linear motor for generating a linear motion in a linear direction, has a plurality of first members, each of which includes an electromagnetic coil for generating a first magnetic field, and a magnetic core (magnetically permeable) having magnetic surfaces being opposite to each other so that the first magnetic field passes a space between the magnetic surfaces, and a second member arranged in the spaces to be relatively movable linearly with respect to a combination of the first members to generate the linear motion in the linear direction, and including a magnet polarized in a polarizing direction to generate a second magnetic field.
