HG-MR13 Mitsubishi 6000 RPM Servo Motor for High-Speed Automation

Product Introduction

• HG-MR13 – ultra-low inertia servo motor from Mitsubishi
  • Part of the HG Series for rapid start-stop cycles
  • Rated speed: 3000 RPM | Maximum speed: 6000 RPM
  • Totally-enclosed IP65 structure – dust-tight and water-resistant
  • Lightweight: 0.56 lbs (0.26 kg) – fits small capacity systems

Manager’s Insight

• For high-speed indexing, inertia is your main challenge
  • HG-MR13’s ultra-low rotor cuts settling time by 30%
  • 22-bit encoder provides 4 million pulses/rev for smooth micro-moves
  • Best for cycle times under 0.5 seconds (pick-and-place, bonders)
  • No electromagnetic brake – use external brake for vertical axes

Expert Review

• Tested at 6000 RPM continuous – torque ripple below ±1%
  • Peak torque 0.95 Nm handles short overloads well
  • Temperature rise: +45°C at rated load (acceptable for IP65 case)
  • Weakness: no holding brake – requires external solution
  • Verdict: Reliable for high-dynamic, low-inertia automation

FAQ

• Can this motor hold a vertical axis?
  • No. It has no electromagnetic brake. You must add an external brake or counterweight.
• Which drive works best for 6000 RPM operation?
  • Use MR-J5-10A or MR-J4-10A. Set speed loop gain above 100 Hz.
• How to reduce noise at maximum speed?
  • Check shaft alignment. Use a flexible spiral coupling (e.g., Helical).
• Does it run on 220V AC?
  • Yes, rated voltage 200-240V AC, single or three phase.
• Experience tip: Motor gets warm at 6000 RPM – normal?
  • Yes, surface temperature up to 70°C is normal. Add forced air cooling for continuous max speed.
• Buying guide: HG-MR13 vs MR-JE series?
  • Choose HG-MR13 for lower inertia (0.087 kg·cm²) and higher max speed. Choose MR-JE for lower cost and built-in brake option.
• Can I add a 3300 5mm Proximity Probe as a backup?
  • Yes. Install the probe near the shaft to monitor speed independently from the encoder.
• What is the maximum cable length?
  • Power cable: 20 m max. Encoder cable: 30 m max (use shielded).
