Abstract
A common-stator macro/micro integrated precision motion one-dimensional linear motor assembly, includes a base, linear guide rails, slide blocks, a U-shaped linear motor stator, a macro motion rotor, a micro motion rotor and a macro/micro integrated platform. A macro and micro motion platforms are connected to form an integrated platform through an elastic member, an outer frame of the macro/micro integrated platform is mounted on the linear guide rails and the slide blocks, the U-shaped linear motor stator is arranged on the base, rotors are respectively mounted on the macro and micro motion platforms, and large-scale overall high-speed motion can be realized when macro and micro rotors are simultaneously driven, and when a motion deviation occurs, the micro motion platform realizes precise displacement output by virtue of elastic deformation due to small inertia and zero friction, and high-frequency motion deviation compensation can be realized by virtue of individual drive.
