When a CNC or automation axis stops because of a failed servo motor, you need a Yaskawa servo motor replacement that matches the original part—not simply a motor with similar power. The wrong encoder, voltage class, shaft configuration, or servo drive can cause compatibility problems and costly downtime. For example, the Yaskawa SGMAV-08A3A2C provides 0.75 kW output, 200 V class operation, 2.39 Nm rated torque, and 3000 rpm rated speed, making it a practical replacement option for compatible Sigma-V motion systems. DUOMI CNC supplies new and discontinued automation spare parts worldwide, helping you source difficult-to-find Yaskawa motors with testing, warranty, and technical support.
A servo motor is part of a complete motion-control system. Before ordering a replacement, you should verify the motor model, servo amplifier, encoder specification, voltage, rated output, speed, torque, shaft configuration, and mounting requirements.
The Yaskawa SGMAV-08A3A2C belongs to the Sigma-V SGMAV low-inertia servo motor family. Its lightweight rotor supports rapid acceleration and deceleration, which is useful when your machine performs frequent short-distance positioning.
For this model, key specifications include:
Because the exact SGMAV-08A3A2C replacement depends on your existing machine configuration, you should confirm the complete part number rather than selecting a motor by wattage alone.
The following comparison helps you quickly identify whether this motor fits your replacement requirement.
| Specification | SGMAV-08A3A2C | Why It Matters for Replacement |
|---|---|---|
| Series | Sigma-V SGMAV | Must match the compatible control system |
| Rated output | 0.75 kW | Determines motor capacity |
| Rated voltage | 200 V AC class | Must match the servo system |
| Rated torque | 2.39 Nm | Important for axis load requirements |
| Rated speed | 3000 rpm | Affects machine operating speed |
| Maximum speed | Up to 6000 rpm | Relevant to high-speed positioning |
| Peak torque | Up to 7.16 Nm | Supports acceleration and disturbance response |
| Motor type | Low-inertia AC servo motor | Suitable for dynamic positioning |
| Encoder | Sigma-V high-resolution encoder, configuration dependent | Must match amplifier requirements |
| Protection | Typically up to IP65 with appropriate installation | Helps protect against dust and splashes |
| Typical applications | CNC and industrial automation | Suitable for compatible motion axes |
Important: option codes can define shaft, brake, encoder, and other configurations. Always verify the nameplate and complete part number before purchasing.
You may need a Yaskawa servo motor for CNC machines when an existing axis develops encoder errors, abnormal vibration, overheating, loss of positioning accuracy, or complete motor failure.
The low-inertia SGMAV design is particularly suitable for applications that repeatedly accelerate and decelerate. Typical examples include:
For example, if a compact CNC axis uses an SGMAV-series motor and suddenly loses positioning accuracy, replacing the motor with a correctly matched model can restore the original motion-control configuration without redesigning the entire axis.
However, you should first determine whether the fault comes from the motor, encoder, amplifier, cable, mechanical load, or parameter settings.
You can reduce replacement errors by following a structured sourcing process.
DUOMI CNC focuses on supplying new and discontinued automation spare parts to customers in more than 100 countries. Its portfolio includes Yaskawa servo motors, drives, PLC modules, HMIs, encoders and other industrial automation components.
For replacement sourcing, DUOMI CNC provides several practical advantages:
DUOMI CNC also supplies automation brands including Siemens, Fanuc, Allen-Bradley, ABB, Yaskawa, Mitsubishi, Danfoss, SEW-Eurodrive, Lenze, Schneider, KUKA, IFM, Heidenhain, SICK and B&R.
This combination is useful when you need a discontinued or hard-to-find Yaskawa servo motor spare part rather than a generic alternative.
Not automatically. You should compare the complete model number, voltage, output, encoder, shaft, brake, mounting dimensions and compatible servo amplifier before confirming a replacement.
It can be suitable for compatible CNC positioning axes because its 0.75 kW output, low-inertia rotor and 3000 rpm rated speed support fast and precise motion. You should still verify the requirements of your specific CNC system.
Yes. DUOMI CNC supplies new, refurbished and used automation spare parts and states that products undergo functional verification before shipment. You can provide the exact Yaskawa part number to confirm availability, condition, warranty and delivery options.
Choosing the correct Yaskawa servo motor replacement starts with the complete part number and system compatibility, not simply the motor’s power rating. For the Yaskawa SGMAV-08A3A2C, you should verify the 0.75 kW, 200 V class, 2.39 Nm torque, encoder, shaft configuration and compatible Sigma-V servo amplifier before ordering. With its global inventory, testing capabilities and automation spare-parts experience, DUOMI CNC can help you identify a suitable replacement and reduce unnecessary machine downtime.
Send DUOMI CNC your complete Yaskawa model number, machine application, required quantity and preferred condition (new, refurbished or used). The team can then check availability, verify the part specifications, provide warranty information and prepare a quotation for your application.
