Buying Considerations: Selection Guide
When selecting the Yaskawa SGMAV-C2A3A21 AC Servo Motor for your application, consider these critical factors:
- Torque Requirements: Calculate both continuous and peak torque needs based on your load inertia, acceleration rates, and friction forces. The 0.64 N·m continuous torque and 1.91 N·m peak torque should match your application demands.
- Speed Range: Ensure your required operating speed falls within the 0-3000 rpm rated range, with occasional peaks not exceeding 6000 rpm maximum speed.
- Load Inertia Matching: The motor's low rotor inertia (0.042 × 10⁻⁴ kg·m²) enables rapid acceleration. Calculate your load inertia ratio to ensure optimal performance - typically 10:1 or less for best response.
- Environmental Conditions: The IP65 rating provides protection against dust and water jets, but consider additional protection if exposed to oils, chemicals, or extreme temperatures.
- Compatibility: Verify compatibility with your existing servo amplifiers and control systems. This motor requires a compatible Sigma-V series drive for optimal performance.
- Feedback Requirements: The 20-bit absolute encoder provides exceptional resolution but requires compatible drive support. Consider your positioning accuracy needs and control system capabilities.
- Mounting Configuration: The 40mm square frame with standard mounting dimensions allows for flexible installation in various orientations.

Frequently Asked Questions
Q1: What type of encoder does the SGMAV-C2A3A21 use, and what are its advantages?
The motor features a 20-bit absolute encoder (1,048,576 pulses per revolution) that provides exceptional positioning resolution and accuracy. Absolute encoders maintain position information even after power loss, eliminating the need for homing sequences and improving system uptime. This high-resolution feedback enables precise control for applications requiring micron-level accuracy.
Q2: Can this servo motor be used with non-Yaskawa drives and controllers?
While technically possible with appropriate interface modules, optimal performance is achieved when paired with compatible Yaskawa Sigma-V series drives. These drives are specifically tuned for the motor's electrical characteristics and provide access to advanced features like vibration suppression, adaptive tuning, and comprehensive diagnostic capabilities. For best results, we recommend using the complete Yaskawa motion control system available through our servo systems selection.
Q3: What maintenance is required for this AC servo motor?
The SGMAV-C2A3A21 is designed for minimal maintenance with permanently lubricated bearings and sealed construction. Regular maintenance should include:
1. Visual inspection for physical damage or contamination
2. Checking electrical connections and cable integrity
3. Monitoring operating temperature (typically below 100°C)
4. Verifying proper ventilation and cooling
5. Periodic encoder alignment checks if experiencing positioning errors
The motor's brushless design eliminates brush wear, and the IP65 rating protects internal components from environmental contaminants. For long-term reliability, ensure proper installation and operate within specified environmental conditions.
