LINEAR DISPLACEMENT DRIVE Russian patent published in 2003 - IPC

FIELD: industrial robotics and all industries where translational movement is required. SUBSTANCE: drive that is primarily used as mobility freedom drive for anthropomorphous robots has active member made in the form of two stranded insulated conductors connected at one end to power supply, opposite ends being interconnected and connected to output rod. Drive is provided in addition with C-shaped magnetic circuits disposed abreast in one plane and with additional spiral-spatial current-conducting member. Turns of spiral-spatial member are disposed in vicinity of butt-ends of C-shaped magnetic circuits. Each turn of main member is connected with aid of taut strut to housing and output rod is joined to extreme turn of main member. EFFECT: reduced size of drive. 1 cl, 2 dwg
