- Thermal Optimization: Advanced cooling design and Class F insulation allow continuous operation at higher temperatures without derating.
- Vibration Suppression: Yaskawa's proprietary motor design minimizes cogging torque and vibration, resulting in smoother operation at low speeds.
- Compatibility: Designed for seamless integration with Sigma-5 servo drives, enabling advanced control features like adaptive vibration suppression and advanced autotuning.
Buying Considerations: Selection Guide
When selecting the Yaskawa SGMPH-01AAA2C servo motor for your application, consider these critical factors:
- Load Matching: Calculate your application's torque requirements including continuous torque for sustained operation and peak torque for acceleration/deceleration. Ensure the motor's 0.32 Nm rated torque and 0.96 Nm peak torque meet your needs.
- Speed Requirements: Verify that your application's maximum speed doesn't exceed the motor's 6000 rpm limit. For continuous operation, stay within the 3000 rpm rated speed.
- Inertia Ratio: For optimal performance, maintain a load-to-motor inertia ratio between 3:1 and 10:1. The motor's low inertia (0.037 kg·cm²) makes it ideal for direct-drive applications.
- Environmental Conditions: The IP65 rating provides protection against dust and water jets, but consider additional protection for washdown or harsh chemical environments.
- Drive Compatibility: This motor requires a compatible servo drive such as Yaskawa's Sigma-5 series. Ensure your control system supports the motor's feedback interface.
- Mechanical Integration: Verify shaft dimensions (8mm diameter with keyway) and mounting configuration match your mechanical design. Consider adding flexible couplings for misalignment compensation.
- Feedback Requirements: The 20-bit absolute encoder eliminates homing sequences but requires compatible drive electronics. For simpler applications, consider incremental encoder versions.
Frequently Asked Questions
Q1: What type of feedback system does the SGMPH-01AAA2C use, and what are the advantages?
The SGMPH-01AAA2C features a 20-bit absolute encoder (1,048,576 pulses per revolution). This high-resolution feedback provides exceptional positioning accuracy (±20 arc-seconds) and eliminates the need for homing sequences after power cycles. Absolute encoders maintain position information even during power loss, reducing startup time and improving system reliability.
Q2: Can this servo motor be used with non-Yaskawa drives?
While technically possible with appropriate interface electronics, optimal performance is achieved with Yaskawa Sigma-5 series drives. These drives support the motor's high-resolution feedback and advanced control algorithms. Using incompatible drives may limit performance features and require additional configuration. For best results, we recommend using matched Yaskawa servo systems.
Q3: What maintenance is required for this servo motor?
The SGMPH-01AAA2C is designed as a maintenance-free component with sealed bearings and IP65 protection. Recommended maintenance includes periodic inspection for physical damage, checking electrical connections, and monitoring operating temperature. Unlike brushed motors, there are no brushes to replace. The primary wear components are the bearings, which typically last 20,000+ hours under normal operating conditions. Regular inspection of associated mechanical components like couplings and gears is also recommended.
