Patent ID: 7250696

Claim:
A linear motor for generating a motion in a linear direction, comprising: a plurality of first members, each of which includes an electromagnetic coil for generating a first magnetic field, and a magnetic core having a gap between magnetic surfaces that are opposite to each other, so that the first magnetic field passes through the gap between the magnetic surfaces; and a second member which is arranged in the gaps of the respective first members, and is movable linearly relative to the first members to generate the motion in the linear direction, said second member including a magnet that is polarized in a polarizing direction to generate a second magnetic field; wherein, the electromagnetic coil of each of said first members has two parts which are situated away from each other on the magnetic core; the magnet of said second member and each of the two parts of the electromagnetic coil of each of said first members are disposed such that they cannot overlap each other in a further direction perpendicular to the linear direction; and the two parts of the electromagnetic coil are positionable opposite each other through the magnet, as seen in the further direction.
