Yaskawa HW9381220-A SGMRS-13A2A-YR11 / SGMRV-05ANA-YR11 AC Servo Motor – SGMRS & SGMRV Series
When a servo motor fails mid-production, the consequences cascade instantly — robotic arms freeze, assembly lines halt, and every idle minute translates directly into lost revenue and missed delivery commitments. In high-throughput manufacturing environments, there is no acceptable substitute for a precisely matched, OEM-specification servo motor. The Yaskawa HW9381220-A, integrating both the SGMRS-13A2A-YR11 and SGMRV-05ANA-YR11 motor configurations, is engineered to eliminate exactly this risk — delivering the torque, speed, and positional accuracy that modern industrial automation demands.
Within Yaskawa’s renowned SGMRS and SGMRV servo motor families, the HW9381220-A occupies a critical position as a high-performance, medium-frame AC servo motor designed for demanding multi-axis robotic and CNC applications. Yaskawa Electric Corporation, a global leader in motion control with over a century of engineering heritage, has deployed the SGMRS/SGMRV series across automotive assembly, semiconductor fabrication, and precision machining worldwide. This specific assembly — pairing a 1.3 kW SGMRS frame with a 0.5 kW SGMRV auxiliary axis — is a factory-configured combination unit used in Yaskawa’s own MOTOMAN robot platforms.
