Yaskawa Electric Corporation SGMSV-20A3A21-01 AC Servo Motor

The Yaskawa SGMSV-20A3A21-01 AC Servo Motor, part of the Sigma-5 family from Yaskawa Electric Corporation, is a 2.0 kW class brushless AC servo motor designed for high-precision speed and position control in industrial automation. It runs on 200 VAC (3-phase) with a rated speed of 3000 RPM and a rated torque of 6.36 Nm, and it uses a 20-bit absolute encoder for high-resolution feedback. The motor is flange-mounted for versatile installation, supports continuous duty operation, and sits in the medium inertia class, making it suitable for CNC machining centers, robotic systems, material handling equipment, and automated production lines where precise positioning and consistent torque are critical. The SGMSV-20A3A21-01 belongs to a compact, high-efficiency series known for improved tuning over Sigma-II models. Common replacements include Yaskawa SGMGV-20A3A21, SGMSV-30A3A21, and SGM7G-20A, reflecting its ongoing aftermarket availability. Status: Legacy (still widely available aftermarket).
