Yaskawa Electric Corporation SGMM-A3S312 Servo Motor

Yaskawa SGMM-A3S312 is a 30 W servo motor in the Sigma Mini SGMM family, engineered for compact, high-precision motion in automation tasks where space is at a premium. This brake-free variant uses a 2,048 P/R incremental encoder to provide feedback for accurate position and speed control, aligning with Yaskawa’s smallest-servo performance profile. In practice, it is commonly paired with Rexroth’s PSK40 precision linear actuator modules to form compact servo-driven linear stages, enabling repeatable motion in a range of automation tasks requiring precise positioning. As with many SGMM motors, the A3S312 is designed for reliable torque and speed control in tight spaces, offering a lightweight, efficient solution for precise servo-driven motion in entry-level automation systems. With a 30 W rating, it provides sufficient torque for small-diameter shafts and short-stroke motions typical of compact automation tasks.
