Compatible Replacement & Equivalent Models
The following models are commonly evaluated as direct or near-equivalent replacements for the SGM-08A3FJ62. Compatibility depends on your servo drive, mechanical interface, and control system — always confirm before substitution.
- YASKAWA SGM7J-08AFC6S — Σ-7 series upgrade; same 750 W output, 23-bit absolute encoder, improved dynamic response. Drop-in mechanical fit with SGDV/SGDH drives requiring parameter adjustment.
- YASKAWA SGMJV-08ADA6S — Σ-V series equivalent; 750 W, 20-bit encoder, compatible with SGDV drives. Recommended for Σ-V system upgrades.
- YASKAWA SGM-08A3FJ61 — Same series variant without brake; suitable when holding brake is not required.
- Mitsubishi HG-SR52 — 500 W Mitsubishi equivalent (cross-brand); requires drive and wiring adaptation. Not a direct drop-in.
- Panasonic MSMF082L1U2M — 750 W cross-brand alternative; compatible with Panasonic MINAS A6 drives only.
⚠ Important: Cross-brand replacements require full system re-commissioning. Consult Konmask technical support for compatibility verification.
Why Choose the Original Model
- Proven reliability in Σ-series servo systems with millions of installed units globally.
- Seamless compatibility with YASKAWA SGDH, SGDM, and CACR-series servo drives — no parameter migration required.
- Integrated holding brake (suffix “J62”) ensures safe vertical axis and gravity-load applications.
- OEM-grade precision with tight torque ripple control, ideal for CNC, robotics, and semiconductor equipment.
- Long service life with YASKAWA’s proven winding and bearing technology.
Typical Applications
- CNC machine tool axes (milling, turning, grinding)
- Industrial robot joint drives
- Semiconductor wafer handling and pick-and-place systems
- Packaging and labeling machinery
- Textile and printing equipment
- Vertical axis applications requiring holding brake (Z-axis, gantry)
- Electronic assembly and SMT equipment
System Compatibility
The SGM-08A3FJ62 is designed to operate with the following YASKAWA servo drive families:
- SGDH series — Primary compatible drive (SGDH-08AE recommended)
- SGDM series — Compatible with appropriate capacity matching
- CACR-SR series — Legacy Σ-II system compatibility
- SGDV series — Compatible with encoder adapter; parameter reconfiguration required
Not compatible with Σ-7 (SGDV7S) drives without mechanical and encoder adaptation.
Selection Guide
Use the following criteria to confirm the SGM-08A3FJ62 is the right choice — or to identify the best alternative:
- Power requirement: If your application needs 750 W continuous output at 3,000 rpm, this model is correctly sized. For higher torque at lower speed, consider a larger frame (SGM-13 series).
- Brake requirement: The “J” suffix indicates a holding brake. If no brake is needed, select SGM-08A3FJ61 to reduce cost and weight.
- Encoder resolution: The standard 2,048 P/R incremental encoder suits most positioning tasks. For absolute positioning or battery-free retention, upgrade to the SGM7J-08AFC6S (23-bit absolute).
- Drive compatibility: Confirm your existing drive model before ordering. Mixing Σ-II motors with Σ-V or Σ-7 drives requires adaptation kits.
- Environment: IP55 rating covers most factory environments. For washdown or outdoor use, specify IP67 variants.
- Shaft configuration: Verify shaft diameter, key dimensions, and flange bolt pattern against your mechanical drawing.

Replacement & Compatibility FAQ
Q: Can I use the SGM-08A3FJ62 with a Σ-7 drive?
A: Not directly. The Σ-7 drive (SGDV7S series) uses a different encoder protocol. An encoder adapter and parameter reconfiguration are required. We recommend upgrading to the SGM7J-08AFC6S for Σ-7 systems.
Q: Is the SGM7J-08AFC6S a direct mechanical replacement?
A: Yes — the flange dimensions and shaft specifications are identical. However, the encoder connector and wiring differ. A new motor cable (JZSP-C7M series) is required.
Q: Can I replace just the encoder on the SGM-08A3FJ62?
A: Encoder replacement is technically possible but not recommended in the field. Contact YASKAWA service or Konmask for motor refurbishment options.
Q: What is the lead time for the SGM-08A3FJ62?
A: In-stock units ship within 1–3 business days. Out-of-stock lead time is typically 4–8 weeks depending on YASKAWA production schedule. Contact us for real-time availability.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. CoC and inspection reports are available upon request for all orders.
