By leveraging the high power density of the Sigma-7 platform, this motor delivers meaningful torque and speed performance even at the 100 W level, making it a practical choice for auxiliary axes and fine motion tasks that still demand professional servo control.

2. Performance Characteristics and Motion Quality

Although the SGM7A-01AFA61 is a low-power servo motor, it inherits the motion performance and control quality of the entire Sigma-7 family:

1. Fast Dynamic Response
   When paired with a Sigma-7 SERVOPACK drive, the motor achieves rapid acceleration and deceleration, allowing short cycle times and precise following of motion profiles. This makes it ideal for positioning operations with frequent start-stop cycles.

2. High Positioning Accuracy
   The motor integrates a high-resolution encoder that supports advanced control algorithms in the SERVOPACK. The combination of fine feedback resolution and sophisticated servo tuning results in excellent positioning repeatability and minimal tracking error.

3. Smooth Low-Speed Operation
   Stable low-speed torque and smooth rotation are crucial for inspection systems, alignment stages, and slow feed processes. The SGM7A-01AFA61 provides smooth, cogging-reduced operation to ensure high surface quality and reliable process control.

4. Wide Speed Range
   The Sigma-7 platform supports a broad speed range, from low-speed creeping motions to higher rotational speeds for rapid transfer or indexing. System integrators can optimize their speed-torque trade-off based on the exact application needs.

3. Mechanical and Electrical Features

The YASKAWA SGM7A-01AFA61 is designed with practical mechanical and electrical details that simplify integration into industrial machinery:

• Standardized Flange Dimensions
  The motor is supplied with a standard metric flange, enabling direct mounting to gearboxes, linear modules, or machine frames without complex adapters.

• Precise Shaft Construction
  The straight shaft allows direct coupling to ball screws, timing pulleys, or flexible couplings. High machining accuracy of the shaft helps reduce radial runout and misalignment, contributing to longer bearing and coupling life.

• Robust Bearing Design
  Bearings are selected for long service life in continuous industrial operation. When properly aligned and loaded within specified limits, the motor provides dependable performance with minimal maintenance.

• Industrial-Grade Insulation and Winding
  The stator windings are optimized for high thermal efficiency and reliability. The motor can withstand typical industrial temperature ranges when operated within the rated load and ambient conditions.

• Clean Cable Interface
  Power and feedback connections are implemented via standardized connectors or cables that integrate seamlessly with YASKAWA drives and existing plant wiring practices.

4. Integration with YASKAWA Sigma-7 SERVOPACK Drives

The SGM7A-01AFA61 is designed to operate with YASKAWA Sigma-7 SERVOPACK servo amplifiers. This tight integration offers several advantages:

• Auto-Tuning and Advanced Control
  Sigma-7 drives provide automatic tuning functions that consider motor characteristics and mechanical load inertia. This allows rapid commissioning with stable performance, even for non-specialist users.

• Vibration Suppression Functions
  Advanced vibration and resonance suppression features help to minimize mechanical oscillations in flexible structures such as long arms, belts, or slender shafts.

• Integrated Safety and Diagnostics
  Depending on the chosen SERVOPACK, functions such as Safe Torque Off (STO), alarms, and detailed diagnostic information are available, enabling faster troubleshooting and safer designs.

• Communication Options
  Sigma-7 drives support a variety of industrial fieldbuses and networks (e.g., EtherCAT, MECHATROLINK, etc., depending on the selected drive model). This ensures that the SGM7A-01AFA61 motor can be easily integrated into modern PLC and motion controller architectures.

5. Typical Application Areas

Thanks to its balance of size, performance, and reliability, the SGM7A-01AFA61 is suitable for a wide range of applications, including:

• Small-Axis Robotics
  Used for wrist joints, grippers, or auxiliary axes in compact robots that require light weight and high responsiveness.

• Electronics and Semiconductor Handling
  Applied in PCB handling, pick-and-place machines, component feeders, and inspection equipment where precise positioning and low vibration are key.

• Packaging and Labeling Machines
  Ideal for film feeding, label application, and miniature index tables that work with light loads at high speeds.

• Laboratory and Medical Automation
  Deployed in small lab instruments, analysis equipment, and medical handling devices, where repeatable micro-motions and low noise are desired.

• Global Support – The motor is part of a globally recognized product family, backed by worldwide technical support and service.

• Scalability – Designers can build machine platforms with different power levels using other Sigma-7 motors, while maintaining the same control architecture, programming style, and communication interfaces.

• Energy Efficiency – High-efficiency windings and optimized control algorithms help reduce energy consumption, particularly in multi-axis systems running continuously.

7. Installation, Commissioning, and Maintenance Guidelines

When applying the SGM7A-01AFA61, correct installation and commissioning are essential to achieving optimal performance:

• Mechanical Mounting
  Ensure the mounting surface is flat and rigid. Any misalignment between the motor shaft and the load can cause vibration, premature bearing wear, and increased noise. Use quality couplings and alignment tools.

• Thermal Considerations
  Operate within the specified ambient temperature and avoid enclosing the motor in completely sealed spaces without considering heat dissipation. Natural cooling must not be obstructed.

• Wiring and Grounding
  Power and encoder cables should be routed according to YASKAWA guidelines, separated from high-noise power lines where possible. Proper grounding minimizes electrical noise and enhances system reliability.

• Drive Parameter Setting
  Use the servo drive setup software or keypad to select the correct motor model (SGM7A-01AFA61) and encoder type. Apply automatic tuning as a starting point, then refine parameters if necessary for the specific mechanical system.

• Routine Inspection
  Periodically check for abnormal noise, temperature rise beyond normal levels, or any visible damage to cables and connectors. Keep the motor surface free from excessive dust or oil buildup.

8. Summary

The YASKAWA SGM7A-01AFA61 AC servo motor is a compact, high-precision member of the Sigma-7 family, designed for demanding industrial automation tasks where space is limited but motion quality cannot be compromised. Its combination of precise encoder feedback, robust mechanical design, seamless integration with Sigma-7 SERVOPACK drives, and suitability for a broad range of small-axis applications makes it an excellent choice for OEM machine builders and system integrators seeking reliable, long-term motion control solutions.
