Abstract: A linear motor heat dissipation structure including multiple teeth arranged linearly at predetermined intervals each with coil wound around rectangular tube-shaped bobbin, and heat dissipation member provided between adjacent coils that dissipates heat generated coils by transmitting the heat to an external section. Heat dissipation member is sandwiched by bowed sections of coils that are curved outwards within edges of rectangular tube-shaped bobbin due to elastic force of coils. Accordingly, even when there are component tolerances and assembly tolerances, those tolerances are absorbed by the elastic deformation of the bowed section of coils such that the variance in the contact state between coil and heat dissipation member is made smaller so that stable and high heat dissipation performance is achieved.

Abstract: A linear motor device comprising: a path member including a magnet extending in a movement direction; and a moving body including a coil that is movably mounted on the path member; the linear motor device generates thrust in the movement direction between the magnet and the coil by current being passed through the coil; the moving body further includes a magnetic shielding target object, and a magnetic shielding member formed from strongly magnetic material that shields the magnetic shielding target. The magnetic shielding member includes a parallel shielding plate provided parallel to the movement direction between the magnetic shielding target object and the magnet, and a perpendicular shielding plate provided extending away from the magnet in a direction perpendicular to the movement direction at at least one of a front edge and a rear edge of the parallel shielding plate in the movement direction.
