Yaskawa Electric Corporation SGMJV-04ADA21 AC Servo Motor

The Yaskawa SGMJV-04ADA21 AC Servo Motor is a compact, brushless servo in the Sigma-5 series that delivers precise speed and position control for small to mid-size automation tasks. This 400 W, 200 VAC three-phase motor provides up to approximately 1.27 Nm of torque at 3000 RPM and uses a 20-bit high-resolution encoder for accurate feedback, supporting continuous-duty operation in demanding environments. With a medium inertia profile and flange-mount, compact frame, the SGMJV-04ADA21 is well suited for robotics, small CNC machines, packaging lines, PCB drilling equipment, semiconductor tooling, pick-and-place systems, and other applications that require fast acceleration and smooth, reliable motion. It is commonly used for replacement, retrofit, expansion, or upgrading servo-driven systems, and is compatible with common replacements such as SGMJV-04ADA61, SGMJV-04A3A21, and SGM7J-04A.
