Good Price Original New AC Servo Motor YASKAWA SGM7A-02AFA61 Bestselling and Good Performance

The YASKAWA SGM7A-02AFA61 is a compact, low-capacity AC servo motor from the Sigma-7 family, designed for precise and responsive motion control in modern automation systems. It is aimed at applications where small power, high accuracy, and fast response are needed in a very limited space, such as compact robots, light-duty positioning units, and high-speed pick-and-place mechanisms.

Within the Sigma-7 range, the SGM7A-02AFA61 belongs to the low-inertia series, which is optimized for rapid acceleration and deceleration. This makes it especially suitable for short-stroke, repetitive motions and systems where cycle time and repeatability are critical. Even though it is a small motor, it is built on the same control concept and quality standards as larger YASKAWA servo models, ensuring long-term stability in continuous industrial operation.

4. Design Concept and Performance

The SGM7A-02AFA61 is engineered as a small but highly responsive axis for advanced automation. In many machines, the smallest axes often work the hardest: they accelerate rapidly, stop frequently, and repeat the same motion thousands of times per shift. The low-inertia rotor and compact stator design of this motor address exactly those conditions.

In a typical system, the motor is paired with a Sigma-7 servo drive that provides:

• High servo bandwidth for rapid response

• Precise current and speed control

• Built-in auto-tuning and resonance suppression features

This combination allows the machine builder to achieve short settling times, tighter positioning, and reduced cycle times without sacrificing stability. The SGM7A-02AFA61 is therefore well suited to roles such as:

• Quick indexing axes

• Lightweight pick-and-place heads

• High-speed feeders and small conveyors

Even at its small capacity, the motor is designed for continuous industrial duty, providing reliable service in production environments operating many hours per day.

5. Encoder System and Control Quality

Like other Sigma-7 motors, the SGM7A-02AFA61 uses an advanced encoder feedback system that communicates with the drive over a serial interface. The high resolution of this encoder enables:

• Fine positioning accuracy, important for small-step motions and tight tolerances

• Very smooth low-speed operation, which is useful in inspection, alignment, or test axes

• Stable speed regulation, even when loads or friction conditions vary

The drive uses this encoder information to perform functions such as vibration suppression and automatic gain adjustment. As a result, end users benefit from:

• Reduced mechanical vibration

• Better tracking performance during complex motion profiles

• Easier startup, since tuning can be simplified

This level of control quality is particularly valuable in electronic assembly machines, test equipment, and compact robot joints, where even small errors can impact yield or accuracy.

6. Mechanical Design and Installation

The mechanical structure of the SGM7A-02AFA61 follows a standardized Sigma-7 form factor, making it convenient to integrate into new or existing designs:

• Flange mounting allows straightforward attachment to machine frames and linear modules.

• The straight shaft with keyway offers secure coupling to pulleys, gears, ball screws, or couplings.

• The slim body and low mass are beneficial for moving axes, such as those mounted on Z-slides or robotic arms, where added weight directly impacts dynamics.

Because it is a small-frame motor, it helps designers minimize overall machine dimensions and build densely packed multi-axis systems. Cables, connectors, and accessories are part of the broader Sigma-7 ecosystem, which simplifies sourcing and maintenance.

When installing the motor, good engineering practice includes:

• Accurate shaft alignment and proper coupling selection

• Adequate support of external loads with bearings or linear guides

• Observing recommended environmental conditions (temperature, humidity, vibration)

7. Typical Applications

The SGM7A-02AFA61 fits a wide range of light-duty, high-precision motion tasks:

Electronics and Semiconductor Equipment
Used in short-stroke slides, tool positioning units, small indexing tables, and device handling modules where millimeter-level or sub-millimeter accuracy is expected.

Packaging and Labelling Machines
Applied to axes for film feeding, label application, product spacing, and small cutting mechanisms. The motor’s fast response supports high-speed packaging lines with frequent stop-start cycles.

Robotics and Handling
Integrated into compact robot joints, grippers, or Cartesian axes carrying light loads. The low inertia supports quick orientation and gripping movements with good repeatability.

Inspection and Measurement Systems
Deployed in vision inspection stages, sensor positioning systems, or test equipment where stable low-speed and micro-positioning performance are crucial.

Custom Machine Builders
OEMs can use the SGM7A-02AFA61 wherever a small, responsive axis is needed but reliability must still match that of larger industrial servos.

8. System Integration Considerations

To obtain the full benefit of the SGM7A-02AFA61, it should be integrated into a properly engineered servo system:

• Select a Sigma-7 drive with suitable current rating for this 200 V class motor.

• Use appropriately rated power and encoder cables, following YASKAWA’s wiring diagrams.

• Ensure good grounding and shielding to reduce electrical noise and protect feedback signals.

• Configure the drive parameters according to the mechanical system’s inertia, load condition, and required motion profile.

• Make use of the Sigma-7 drive functions such as auto-tuning and vibration suppression to shorten commissioning time.

Following these steps helps maintain both performance and reliability, especially in multi-axis machines with complex motion patterns.

9. Advantages for OEMs and End Users

Choosing the YASKAWA SGM7A-02AFA61 brings several practical benefits:

• Compact, low-capacity solution for space-critical designs
