Yaskawa Sigma-7 Rotary Servo Motors

Yaskawa Sigma-7 rotary motors cover multiple frames, inertias and electrical configurations. The manufacturer describes selected Sigma-5 compatibility conventions, but this does not make every SGM7 a drop-in replacement. Sigma-7 is an established platform; Yaskawa’s current portfolio also includes Sigma-X.

Review Summary
Consider SGM7 for a supported amplifier and actual load cycle, including validated Sigma-family replacement projects. Select winding, feedback, shaft and options together. Family torque-density claims do not replace a configuration-specific torque/speed and thermal assessment.
