Yaskawa SGMGV-20DDL6F Σ-V Series 1.8kW AC Servo Motor

The Yaskawa SGMGV-20DDL6F is a high-torque, high-precision AC servo motor from the Σ-V Series. Designed for demanding applications that require both high power density and dynamic accuracy, this 1.8 kW model operates on a 400 V three-phase power supply, reducing current draw and allowing longer cable runs. It is ideal for use in machine tools, material handling systems, robotics, and high-speed packaging equipment.

High Torque Density and Stability

The SGMGV-20DDL6F provides high torque density, offering both continuous and peak torque ratings capable of handling substantial loads while maintaining a compact frame size. This makes it well-suited for machine tool feed axes and large-capacity robots. The permanent magnet construction, combined with Class F insulation, provides high efficiency and reliable thermal performance, allowing the motor to be used in demanding cycles without exceeding thermal limits.

Absolute 20-bit Serial Encoding

The integrated 20-bit high-resolution absolute serial encoder is a key feature of this Σ-V motor. With 1,048,576 pulses per revolution, it ensures exceptionally smooth rotation even at low speeds, high settling accuracy, and eliminates the need for homing after power up. This is critical for CNC applications where position must be retained when the machine is powered down.

IP67 Protection and Environmental Durability

The motor case is rated IP67 (excluding the shaft passage), making it resistant to dust, water jets, and temporary immersion. This allows it to be used in harsh washdown environments such as food processing machinery or machine tools exposed to coolant splash.

24 V Holding Brake

The integrated 24 V DC holding brake is a fail-safe spring-engaged, electrically-released brake that automatically holds the motor shaft when the power is removed. This is essential for vertical axes (e.g., Z-axis milling heads, robotic arms) to prevent the load from dropping when the drive is disabled.

Conclusion

With its 1.8 kW output, 400 V operation, IP67 construction, and high-resolution absolute feedback, the SGMGV-20DDL6F is the ultimate servo motor for high-performance automation tasks where space is limited, uptime is critical, and reliability is key.
