Buying Considerations: Selection Guide
When selecting the Yaskawa SGM-01A314B servo motor for your application, consider these critical factors:
- Load Matching: Calculate your application's torque requirements including acceleration, deceleration, and holding torque. The 0.32 Nm rated torque and 0.95 Nm peak torque must exceed your maximum operational demands.
- Speed Requirements: Ensure the 3000 rpm rated speed and 6000 rpm maximum speed align with your process requirements. For high-speed applications, consider servo amplifiers with appropriate bandwidth.
- Environmental Conditions: The IP65 rating makes this motor suitable for environments with dust or light water exposure, but verify compatibility with your specific industrial conditions.
- Compatibility: This motor requires compatible Yaskawa Sigma series servo drives (SGDV series). Ensure proper drive-motor pairing for optimal performance.
- Mounting Configuration
: The 40mm square frame supports standard NEMA mounting patterns, but verify flange dimensions and shaft specifications match your mechanical design.

Frequently Asked Questions
Q1: What type of encoder does the SGM-01A314B use and what are its advantages?
The SGM-01A314B features a 20-bit absolute encoder that provides 1,048,576 pulses per revolution. This high-resolution feedback enables precise positioning (±0.01 degrees) without requiring homing sequences after power loss. Absolute encoders maintain position information even during power outages, reducing setup time and improving system reliability.
Q2: Can this servo motor be used with non-Yaskawa drives?
While technically possible with appropriate interface modules, optimal performance is achieved with Yaskawa Sigma series servo drives (SGDV series). The motor-drive pairing ensures proper communication, tuning, and protection features. For best results, use compatible Yaskawa servo drives designed for this motor series.
Q3: What maintenance is required for this servo motor?
The SGM-01A314B is designed for minimal maintenance with permanently lubricated bearings and sealed construction. Regular inspections should include checking for abnormal vibration, monitoring temperature (rated for 40°C ambient), and ensuring proper cable connections. The IP65 rating protects against dust ingress, but periodic cleaning of cooling fins may be necessary in dusty environments. For replacement parts, browse our servo motor accessories section.
