Good Price New AC Servo Motor YASKAWA SGM7A-06A7A61 High Quality and Stable Performance

1. Product Overview

The YASKAWA SGM7A-06A7A61 is an AC servo motor from the Sigma-7 family, designed for applications that demand accurate positioning, fast dynamic response, and long-term reliability. Belonging to the 0.6 kW class, this motor is well suited for compact axes in packaging machinery, assembly equipment, light CNC machines, and high-speed handling systems.

In a modern automation system, the SGM7A-06A7A61 is typically paired with a corresponding Sigma-7 SERVOPACK, forming a complete servo solution. The motor and drive combination provides precise control of position, speed, and torque, while also offering advanced auto-tuning and diagnostic functions to shorten commissioning time and reduce maintenance effort.

The motor is based on a permanent magnet synchronous design, which delivers a high torque-to-inertia ratio, smooth low-speed behavior, and stable performance over a wide operating range. This makes it a strong choice for OEMs and end users who need consistent, repeatable motion in continuous production environments.

2. Key Specification Summary

This table is intended as a selection guide. For detailed engineering work, torque-speed curves and dimension drawings should be taken from the official YASKAWA documentation.

3. Design Features and Performance Characteristics

The SGM7A-06A7A61 combines several design features that target real-world machine requirements rather than just laboratory specifications:

1. High dynamic response
   The rotor and magnetic design enable rapid acceleration and deceleration. This allows short move times and minimal settling time, improving the throughput of indexing, positioning, or pick-and-place mechanisms.

2. Fine positioning capability
   The high-resolution encoder provides detailed feedback, so the Sigma-7 drive can control the motor position with high precision. This is essential when the axis must repeatedly reach the same target within a narrow tolerance window.

3. Smooth low-speed operation
   Even at very low speeds, the motor maintains stable torque and smooth rotation. This behavior is important in applications such as slow feed movements, careful alignment, or inspection processes where jerk and vibration must be minimized.

4. Compact format with high torque density
   The 0.6 kW power class is packed into a compact housing, giving machine builders more freedom when designing small enclosures or tight mechanical layouts.

5. Industrial durability
   The motor is built for industrial conditions, with bearings, insulation, and mechanical structure designed for continuous duty. When installed correctly, it can support long running hours with minimal downtime.

4. Typical Application Areas

Because of its power level and mechanical size, the SGM7A-06A7A61 fits naturally into a range of medium-duty axes:

• High-speed packaging equipment
  Used for film feed rolls, cutting cylinders, and sealing mechanisms where position and timing must remain synchronized with conveyors and product flow.

• Assembly and handling systems
  Drives small linear axes, rotary indexing tables, or part manipulators that move components between assembly stations with high accuracy and short cycle times.

• Compact CNC and machine tools
  Suitable for tool changers, auxiliary axes, or light machining axes that require the balance of speed, stiffness, and precision typical of servo technology.

• Electronics and semiconductor production
  Used to position carriers, trays, or inspection heads in processes that require stable, repeatable motion and gentle handling of delicate components.

• Testing, measurement, and inspection equipment
  Provides controlled movement of sensors, probes, or fixtures where repeatability and smooth motion directly influence measurement quality.

5. Integration with Sigma-7 Servo Drives

The SGM7A-06A7A61 is designed to work seamlessly with Sigma-7 SERVOPACK drives, and this integration simplifies the complete motion solution:

• Parameter compatibility
  The motor characteristics are recognized by the drive, reducing manual parameter entry and the risk of configuration errors.

• Auto-tuning functions
  The drive offers automatic gain tuning and vibration suppression. These features measure the mechanical system and apply suitable control parameters, which is especially valuable when the machine structure is flexible or when the inertia ratio is not ideal.

• Support for modern motion networks
  Depending on the drive model, the system can connect to Ethernet-based motion networks or widely used fieldbuses. This enables integration into PLC-based architectures and multi-axis motion controllers.

• Built-in diagnostics
  Alarm history, trace functions, and monitoring tools allow technicians to quickly identify and correct problems, reducing downtime and maintenance cost.

6. Installation and Engineering Notes

To take full advantage of the SGM7A-06A7A61, several engineering details should be considered:

• Use appropriate couplings and alignment to minimize vibration and bearing load.

• Check load inertia against motor inertia to stay within recommended ratios. Proper inertia matching improves responsiveness and stability.

• Select shielded cables of the correct length and rating, and route them away from noise sources such as high-power inverters or large contactors.

• Confirm that environmental factors such as temperature, humidity, and contamination stay within the permitted range. Additional sealing or mechanical protection may be needed in harsh environments.

• Choose a version with a holding brake if the motor drives a vertical axis or any load that must be safely held when power is removed.

7. Benefits for OEMs and End Users

Implementing the YASKAWA SGM7A-06A7A61 in a machine or production line brings several practical advantages:

• Higher productivity
  Shorter acceleration and deceleration times, combined with precise stopping, increase the number of cycles per minute and raise the effective output of the equipment.

• Quality and consistency
  Accurate position and speed control reduce variation in filling volume, cutting length, alignment, or other quality-critical parameters.

• Reduced commissioning time
  Auto-tuning and clear engineering tools shorten setup, which is especially important for OEMs that build multiple identical machines.

• Long-term reliability
  Proven YASKAWA servo technology, global support, and stable performance over time help minimize unplanned downtime and lifecycle cost.

• Scalability and future upgrades
  As part of the Sigma-7 ecosystem, the SGM7A-06A7A61 fits into scalable multi-axis architectures, making future machine expansions or upgrades easier to plan.

8. Conclusion

The YASKAWA SGM7A-06A7A61 AC servo motor is a compact yet powerful solution for medium-duty motion control tasks. By combining high dynamic performance, precise feedback, and seamless integration with Sigma-7 SERVOPACK drives, it provides a stable platform for modern industrial machinery.

Whether it is installed in packaging lines, assembly cells, light CNC equipment, or specialized testing systems, this motor helps deliver fast, accurate, and reliable motion, supporting higher productivity and consistent product quality throughout the life of the machine.
