As a result of attempting the optimization of iron core shape of a cylindrical linear synchronous motor (C-LSM) in which thrust per unit product is large, following matters became clear:<br>1. The suction force is produced in the stator edge between mover and bearing, since magnetic material is used for a part of the linear bearing. It is one of the error factors in calculating the static thrust characteristics.<br>2. The maximum static thrust changed 3.7 newtons by the existence of the salient pole of the mover while detent thrust changed only 0.39 newtons. It is proven that the maximum detent thrust does not change by establishing salient pole, and simultaneously the maximum static thrust can be improved 6.7%.<br>3. The relationship between maximum static thrust and open width of the semienclosed slot is calculated by using FEM. The maximum static thrust of 57.3 newtons can be obtained, and detent thrust / maximum static thrust ratio is made 4% when the width of the semienclosed slot is made to 1mm. The calculation is verified in a measerment of a test machine.<br>4. As the result of measuring the speed control characteristics of the C-LSM, speed error can be supressed to 5% under the condition of driving speed 80mm/s.
