Selection Guide
Use the following criteria to confirm the SJ-PF7.5-01 is the correct model for your application:
- Power requirement: Confirm load torque and speed profile require 7.5 kW continuous output.
- Drive pairing: Match with MR-J3-70_ or MR-J4-70_ amplifier (70 = 7.0 kW class).
- Encoder suffix (-01): Indicates specific encoder variant — verify against your servo amplifier’s encoder input specification.
- Mounting interface: Confirm flange dimensions (IEC/JIS standard) and shaft diameter match your mechanical design.
- Environment: IP65 rating suitable for light coolant splash; not suitable for full immersion.
- Voltage supply: Requires 3-phase 200–230 V AC; confirm site power availability.
If your application requires a different power class, consider: SJ-PF4.0-01 (4.0 kW), SJ-PF5.5-01 (5.5 kW), or SJ-PF11-01 (11 kW).

Replacement & Compatibility FAQ
Q: Can I use the SJ-PF7.5-01 with an MR-J4 amplifier?
A: Yes, the SJ-PF series is compatible with MR-J4 amplifiers in the same power class. Verify the encoder cable connector type before installation.
Q: What is the difference between SJ-PF7.5 and SJ-PF7.5-01?
A: The -01 suffix denotes a specific encoder or design revision. Always match the full model number to your servo amplifier’s motor compatibility list.
Q: Is a Yaskawa SGMGH series motor a direct replacement?
A: No. Cross-brand substitution requires mechanical adaptation, drive parameter reconfiguration, and engineering validation. Contact us for guidance.
Q: Do you provide warranty on this product?
A: Yes. Konmask offers a standard 12-month warranty against manufacturing defects on all verified-authentic units.
Q: Can you source other SJ-PF series models?
A: Yes. We stock and can source the full SJ-PF range. Contact us with your model number for availability.
