SGM7G-30AFA61 Yaskawa Industrial Servo Motor 220V / 380V / 480V 3000rpm 1.5Kw
SGM7G-30AFA61 Description
The Yaskawa SGM7G-30AFA61 is a high-performance, medium-capacity servo motor from the flagship Σ-7 (Sigma-7) series. It is engineered to deliver a superior balance of high torque, robust performance, and high-speed capability for demanding industrial automation systems. Designed to be paired with a compatible Σ-7 series servo drive (e.g., SGD7S), this motor excels in applications requiring powerful, smooth, and precise motion control. The "G" suffix indicates a standard inertia design, making it versatile for a wide range of general industrial applications. It incorporates a high-resolution absolute encoder, enabling precise positioning without the need for a homing sequence after a power cycle. The SGM7G-30AFA61 is a core component for driving high-performance machinery that demands reliability, efficiency, and outstanding dynamic response.
SGM7G-30AFA61 Features
- •
Superior Dynamic Performance: Part of the Σ-7 series, it offers a high speed response frequency for outstanding settling characteristics and superior disturbance rejection, ensuring stable and accurate positioning even under variable loads.
- •
High-Resolution Multi-Turn Absolute Encoder: Equipped with a 24-bit (16,777,628 pulses/rev) battery-less multi-turn absolute encoder. This eliminates the need for homing on power-up, provides absolute position over multiple rotations, and contributes to extremely smooth low-speed operation and high positioning accuracy.
- •
High Torque & High-Speed Capability: Delivers high rated and maximum torque in a compact frame, and supports high rotational speeds, enabling faster machine cycles and the ability to handle heavier loads.
- •
High Efficiency & Low Heat Generation: Features an optimized magnetic circuit design and high-quality materials that minimize electrical losses, improving energy efficiency and reducing heat rise.
- •
High Rigidity & Durability: Built with robust mechanical components, including a high-rigidity shaft and high-grade bearings, ensuring long service life and reliable operation in harsh industrial environments.
- •
Advanced Vibration Suppression: When paired with a Σ-7 drive, it takes full advantage of the drive's Advanced Vibration Suppression Control II+, minimizing machine resonance and enabling smoother operation at all speeds.
- •
Oil Seal & Brake Options: Available with an optional shaft seal (designated by suffix) for environments exposed to oil mist or chips, and an optional electromagnetic brake for holding loads during power-off.
SGM7G-30AFA61 Material & Primary Uses
- •
Material: The motor frame is a high-strength aluminum alloy die-casting for effective heat dissipation and light weight. The stator uses premium electromagnetic steel laminations and high-energy neodymium-iron-boron (NdFeB) permanent magnets. The rotor shaft is precision-machined, hardened steel. Seals are high-grade nitrile rubber or fluororubber.
- •
- •
Machine Tools: Driving feed axes (X, Y, Z), tool changers, and turrets in CNC machining centers, lathes, and milling machines.
- •
Industrial Robotics: Acting as the primary actuator for the base, arm, and wrist joints of medium-to-large articulated and gantry robots.
- •
Packaging & Converting: Powering high-torque main drives for form-fill-seal machines, large baggers, printing presses, and rotary die cutters.
- •
Material Handling: Driving rollers, conveyors, and palletizers that require high starting torque and precise speed control.
- •
Injection Molding Machines: Controlling the screw movement for precise metering and injection phases.
