MECHATRONIC MODULE FOR LINEAR DISPLACEMENT Russian patent published in 2009 - IPC F16H1/34 

FIELD: machine building.

SUBSTANCE: present invention pertains to machine building and instrument making, particularly to mechatronic modules for linear displacement, and can be used for precision conversion of rotation of the magnetic field of a stator to translational displacement of an output member of nano-technological equipment, adaptive optical systems, measuring instruments etc. The mechatronic module for linear displacement has an electric motor, a controller for controlling motion of the motor, transmission, comprising slide (4) and support (2, 3) nuts and threaded roller (1). Threaded roller (1) is rigidly joined to ferromagnetic rolling rotors (5). Stator coils (7) and permanent magnets, creating rotating asymmetric magnetic field, are rigidly joined to support nuts (2, 3). The support parts of roller (1) have matching threads with support nuts (2, 3), for which the thread angle has the same value but opposite sign. Slide nut (4) has matching threads with the moving part of roller (1) with different thread angles on the slide nut and the moving part of the roller.

EFFECT: increased accuracy and smoothness of operating a mechatronic module with reduced costs of making it.
