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.
