Abstract
A linear motor actuator includes a raceway member 16 having a cylindrical shape in which a moving block moves in a hollow portion, the raceway member having a cross-sectional shape which has a narrower opening 15 than a width of the moving block 40 in part of the cylindrical shape and having a guide portion (rolling grooves 14 or the like) for guiding the moving block 40 in a cylinder axis direction on an inner surface of the cylindrical raceway member 16, the moving block 40 which is guided by the guide portion so as to move in the cylinder axis direction within the raceway member 16, a cylindrical or prismatic first magnet 18 which resides in an interior of the raceway member 16 to generate a magnetic force, and a second magnet (armatures 46 or the like) which resides on the moving block 40 side and which is shaped to encapsulate the first magnet 18.
