Yaskawa SGMKS-44A5A2S

1. OverviewThe SGMKS-44A5A2S is a high-performance servo motor from Yaskawa, designed specifically for industrial automation applications demanding high precision, fast response speeds, and reliable operation. This motor series is typically paired with Yaskawa servo drives (such as the Σ-7 and Σ-5 series) to achieve closed-loop control.
2. Key Specifications

3. Product Features

• High Response Speed: Adopts Yaskawa’s proprietary field-oriented control (FOC) technology, enabling acceleration and deceleration commands to be executed within milliseconds.
• High-Precision Positioning: Equipped with a high-resolution encoder, ensuring closed-loop control error is generally within ±0.01°.
• Compact Structure: Compared with traditional asynchronous motors of the same power rating, it has a smaller footprint and lighter weight, facilitating installation in space-constrained equipment.
• Superior Reliability: Integrated with overload protection, overheat protection, and dustproof and waterproof designs, making it suitable for harsh industrial environments.
• Excellent Compatibility: Supports a wide range of Yaskawa servo drives and control software (e.g., MotionWorks), simplifying system integration.

4. Structure and Components

• Motor Body: Consists of stator, rotor, and bearings (usually ball bearings or magnetic bearings).
• Encoder: Optical or magnetic encoder directly mounted on the motor shaft.
• Terminal Block: Provides power, signal, and grounding terminals, compliant with IEC/ISO standards.
• Heat Dissipation Device: Metal heat sink or air-cooled structure to ensure effective thermal management during long-term operation.
• Protective Housing: Delivers dustproof and waterproof performance in line with the specified IP rating.

5. Typical Application Fields

• CNC machine tools (lathes, milling machines, grinding machines)
• Robot joints (industrial robots, collaborative robots)
• Packaging machinery (high-speed packaging systems, sorting systems)
• Printing and textile equipment
• Semiconductor and precision assembly (lithography machines, pick-and-place machines)

6. Installation and Maintenance Guidelines

• Pre-Installation Inspection: Verify power matching between the motor and drive, ensure axial alignment, and check terminal block markings.
• Mounting Method: Use flanges or bolt seats provided by the manufacturer for rigid installation to prevent resonance.
• Wiring: Comply with IEC 60204-1 standards, implement protective grounding properly, and avoid electromagnetic interference.
• Commissioning: Configure parameters (e.g., gain, limit values, acceleration/deceleration time) via Yaskawa MotionWorks software, and conduct no-load and load tests.
• Routine Maintenance:Troubleshooting: Yaskawa’s fault code manual helps quickly identify issues such as encoder desynchronization and overcurrent protection triggers.
  • Regularly inspect bearing lubrication status (for ball bearings).
  • Clean dust on the heat sink to keep the heat dissipation channel unobstructed.
  • Monitor for abnormal temperature, vibration, and current, and replace faulty components promptly.
