YASKAWA SGM-04A314 AC Servo motor

Buy online your YASKAWA SGM-04A314 AC Servo motor from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

The Yaskawa Electric SGM-04A314 is a compact brushless AC servo motor used for the precise positioning of CNC axes and automated machines. It operates in a closed-loop system with a SERVOPACK servo drive to ensure stable control of torque, speed, and position. It is primarily used on machine tool axes, indexing tables, and transfer systems. It is also used in automated material handling equipment requiring precise and repetitive motion.

This motor delivers 400 W of power at 200 VAC with a rated current of 2.6 A and a maximum speed of 3000 rpm. Its brushless design reduces mechanical wear and ensures high reliability in continuous production. It is designed to operate in industrial environments with intensive duty cycles.

The SGM-04A314 is often used as a replacement part for a faulty servo motor. The most common failures involve the encoder, overheating, or mechanical jamming of the shaft. Ensuring the correct part number, connector type, and servo drive parameters is essential to guarantee direct compatibility with the existing system.

Each motor can be tested before dispatch on CNC simulators to verify feedback integrity, commutation and operational behavior. Industrial protective packaging, worldwide shipping and support for repair, exchange or sourcing of obsolete YASKAWA components may be available depending on stock and service conditions.

Frequently asked questions about SGM-04A314:

Which YASKAWA drives can run this motor?
Pair it with a corresponding SERVOPACK of the same series, voltage class and power rating, commonly from the SGDA or SGDB families. Always verify the motor suffix and drive nameplate to confirm a correct electrical match.

What encoder type is used on this model?
The SGM platform uses factory-specified encoder feedback defined by the suffix code. Check the nameplate or datasheet to confirm incremental or absolute type and pulse count before ordering a replacement unit.

Does the SGM-04A314 include a holding brake?
Brake availability depends on the exact suffix. If your axis is vertical or requires load holding at power off, confirm brake presence and voltage against the original motor part code.

Is it a drop-in replacement for my existing SGM motor?
If the mechanical flange, shaft dimensions, connector orientation and suffix match your original unit, it is typically a drop-in fit. Review cabling compatibility and drive parameter settings during commissioning.

Can Cnc-shopping provide refurbished or tested units?
