Abstract

PURPOSE:To prevent the second conductor from being deformed, by mounting the stator of a linear motor, on wheels running on rails supported with a concave strip member for the second conductor made of non-magnetic steel on the ground side with a non-magnetic plate arranged on a magnetic steel plate. CONSTITUTION:A rail member 2 made of non-magnetic steel is set on a supporting stand 5. On the upper surface of the rail member 2, along the central line, a concave strip 2a is formed, and in the strip 2a, the second conductor 1 consisting of a non-magnetic plate 1a and a magnetic steel plate 1b is fitted. The upper surface of the both side sections 2b of the rail member 2 is arranged on the level same as that of the upper surface of the second conductor 1, and functions as rails for supported wheels 4. On the wheels 4, the stator 3 of a linear motor is mounted. As a result, the second conductor 1 can be prevented from being deformed and the dimension of a space can be prevented from being fluctuated due to abrasion.
