KUKA 1FK7063-5AF71-1SY3-Z S77 SERVO MOTOR T269156

Siemens Simotics S-1FK7 Compact line, specifically customized for KUKA Robotics (often associated with KUKA Art. Nr. 00-179-159). The "S77" suffix is the critical KUKA designator. While the motor body is a Siemens 63-frame, the S77 spec ensures the mechanical shaft, flange, and internal feedback (likely a specialized resolver) are matched perfectly for the wrist or upper-arm axes of KUKA KR series robots.
