Yaskawa SGMJV-08ADA21 Medium-Inertia Rotary Servo Motor – Extended Overview

The Yaskawa SGMJV-08ADA21 is a high-performance, medium-inertia rotary servo motor from the Σ-V series, designed for precision motion control applications in industrial automation. This model delivers a rated output of 0.75 kW (750 W) and operates on a AC200V power supply, making it suitable for a wide range of machinery requiring reliable and accurate positioning.

Key Features and Performance Highlights

●High-Resolution Feedback: Equipped with a standard 20-bit incremental serial encoder, this motor provides exceptional position and speed feedback accuracy. The Σ-V series also supports 13-bit encoder options, ensuring flexibility for various control requirements.

●High Torque Capability: The motor offers a瞬时大转矩 (instantaneous maximum torque) of 350% of the rated torque, enabling rapid acceleration and deceleration, essential for dynamic applications.

●High-Speed Operation: Capable of reaching a maximum speed of 6,000 r/min, the SGMJV-08ADA21 supports high-speed processes without compromising precision.

●Compact and Versatile Design: With a medium-inertia rotor design, this motor balances responsiveness and stability, making it ideal for applications requiring both quick moves and smooth operation. The standard shaft configuration is a straight shaft without a keyway, and the motor is flange-mounted for easy integration.

●Wide Power Range: Part of a comprehensive family covering 50 W to 750 W, including models with holding brakes, the SGMJV series offers scalability for different machine designs.
