Expert Review

The HG-MR23 excels in high-speed, low-inertia applications. Its dual encoder feedback removes the need for separate limit sensors. The straight shaft simplifies coupling, reducing installation errors. IP65 rating makes it reliable in dusty or wet environments. For 0.2 kW class motion control, this motor offers excellent value and Mitsubishi build quality.

Manager‘s Insight

We recommend the HG-MR23 for upgrade projects from older MR-J2S systems. Its 6000 RPM max speed suits pick-and-place and high-speed conveyors. The compact size saves cabinet space. Stock levels are stable, and spare parts remain available. A solid choice for OEMs seeking certified, long-life servo motors.

Suitable Devices & Applications

• Robotic arms (assembly and soldering)
• CNC routers and engraving machines
• Automated pick-and-place systems
• Labeling and packaging machines
• Small conveyor drives
• Medical device positioning stages

Frequently Asked Questions (FAQ)

Q: Can I use this motor without a brake?
A: Yes. The HG-MR23 has no brake. For vertical loads, add an external brake or use a different model.

Q: Does it support absolute positioning after power loss?
A: Yes. The absolute encoder retains position data. No homing routine needed on restart.

Q: What drive works best with HG-MR23?
A: Use MR-J4-10B or MR-J4-20A from MELSERVO-J4 series.

Q: Is the shaft key included?
A: Yes. The straight shaft key is inside the package.

Q: How do I clean the motor?
A: Wipe with a dry cloth. IP65 allows low-pressure water rinse, but avoid high-pressure jets.

Q: Can it replace a 3300 5mm Proximity Probes system?
A: No. That is a different sensor type. For vibration or position monitoring, see 5mm Proximity Probes.

Q: What is the maximum cable length?
A: Keep encoder cables under 30 meters. Power cables up to 20 meters for full torque.

Q: Can I use this with non-Mitsubishi drives?
A: Not recommended. Encoder protocol is proprietary to Mitsubishi J4 series.

Q: Does the motor get hot at full load?
A: Surface temperature may reach 80°C. This is normal under rated conditions.

Selection Guide

• Torque needs:
  • Need 0.64 Nm rated torque? Choose HG-MR23.
  • For higher torque, select HG-MR43 (1.3 Nm) or HG-MR73 (2.4 Nm).
• Axis type:
  • Vertical axis applications require a brake – pick HG-MR23B.
  • Horizontal axis – HG-MR23 works fine.
• Environment:
  • Harsh washdown? IP65 is sufficient.
  • For submersion, choose IP67 models.
• Shaft preference:
  • Straight shaft reduces cost and alignment time.
  • Keyway shaft available on request.
