ELECTROMECHANICAL ORBITAL END-TYPE SYSTEM Russian patent published in 2002 - IPC

FIELD: drive mechanisms of industrial robots operating, mainly in angular-coordinate systems. SUBSTANCE: system includes stators and rotors mounted on rotated foundation and provided with magnetic coupling and having air gap relative to stators. System has two types of stators including along their length short and long concentric magnetic circuits with winding having frontal portions. Said portions of windings of short magnetic circuits are arranged in zone adjacent to air gap. Frontal portions of windings of long magnetic circuits are arranged in space under frontal portions of windings of short magnetic circuits. EFFECT: enhanced efficiency of apparatus, increased torque. 2 dwg
