SGMG-09VSAB is an original Yaskawa medium-inertia AC permanent magnet servo motor belonging to classic Sigma-II (ΣⅡ) SGMG product lineup, made in Japan and specially matched with Yaskawa SGDM series servo drives for three-phase 200V AC industrial power supply system. With rated power of 0.85kW (marked as 09 in model code), this motor is widely adopted in CNC machine tools, automated production lines, packaging machinery, textile equipment and small industrial robotic arms that require stable high-precision motion control. Medium rotor inertia design delivers smooth acceleration and deceleration performance to avoid mechanical impact during frequent start-stop operation under medium-load working conditions.

SGMG stands for medium inertia servo motor series of Sigma-II platform; digit 09 represents 0.85kW rated output power; letter V indicates three-phase 200V AC input voltage specification; S means solid straight output shaft equipped with parallel key and threaded hole at shaft end; AB configuration refers to built-in 8192PPR incremental optical encoder and no built-in electromagnetic holding brake with standard B5 flange installation structure.

The motor runs on three-phase AC200V wide input voltage ranging from 170V to 264V, featuring 1500rpm rated rotational speed and 3000rpm maximum allowable speed. Its continuous rated torque reaches 5.39N·m while instantaneous peak torque can hit 13.8N·m to realize 300% short-time overload capacity for sudden heavy load impact resistance. Rated operating current is 7.1A with Class-F winding insulation which can withstand maximum ambient temperature up to 155℃ to guarantee long-term stable continuous operation. An integrated 8192 pulse per revolution incremental encoder is preinstalled inside motor housing to provide high-resolution real-time position and speed feedback for servo closed-loop control, effectively improving positioning accuracy and running stability at low speed to eliminate low-speed crawling and vibration issues.

This servo motor adopts totally enclosed natural air cooling structure without extra external cooling fan for compact outline and easy layout inside narrow equipment cabinet. Standard B5 flange mounting style supports both horizontal and vertical installation to fit diverse mechanical connection requirements. The solid output shaft comes with standard flat key and end tapping hole for convenient coupling or reducer direct connection without extra modification on transmission components. Two separate aviation plug terminals are reserved respectively for power cable and encoder signal wiring, facilitating on-site wiring, inspection and later maintenance independently. Overall motor weight is approximately 7.8kg with IP65 protection grade at shaft extension end to prevent water splash and dust intrusion in ordinary industrial workshop environment.

Thanks to medium rotor inertia characteristic, the motor balances dynamic response and load adaptability perfectly, performing outstandingly on equipment with medium inertia load and frequent speed regulation demands. Strong short-period overload tolerance helps tackle occasional transient overload during equipment startup and processing. Optimized internal winding and magnetic circuit design cuts down operation noise and temperature rise during continuous long-hour running. It is the preferred matching servo component for retrofitting old-generation automation equipment and newly-built medium-precision automatic machinery across packaging, textile, woodworking and numerical control processing industries.
