HG-SR102J Mitsubishi HG Series Servo Motor 3000 RPM 22-Bit Encoder

Product Introduction

• HG-SR102J – AC servo motor from Mitsubishi
  • Part of the HG Series for medium to high torque needs
  • Nominal torque: 4.8 Nm | Peak torque: 14.3 Nm
  • Rated speed: 2000 RPM | Maximum speed: 3000 RPM
  • IP67 rating – fully dust-tight and waterproof
  • Includes oil seal for longer life in tough environments

Manager’s Insight

• For applications needing strong torque and reliability, this motor stands out
  • 22-bit absolute encoder gives precise feedback without homing each power-up
  • Flange mounting (130x130mm) makes installation simple and secure
  • Handles high loads: radial 980 N, axial 490 N
  • Straight shaft design works with standard couplings
  • No brake included – use external brake for vertical holding

Expert Review

• Tested under heavy cycles – torque output stays steady even near peak load
  • Temperature rise is well controlled at 2000 RPM continuous
  • IP67 and oil seal make it suitable for wet or dusty workshops
  • Weakness: heavier than some competitors (2.27 kg), but built very tough
  • Verdict: Great choice for packaging, machine tools, and conveyors

FAQ

• Does this motor work underwater?
  • No. IP67 means it survives temporary immersion (1 meter, 30 minutes). Do not run fully submerged.
• Which drive is best for full torque at 3000 RPM?
  • Use MR-J5-40A or MR-J4-40A. Set current limit to 17 A.
• Experience tip: Motor vibrates at low speed
  • Increase speed loop gain slowly. Use auto-tuning first. Check coupling alignment.
• Buying guide: HG-SR102J vs HG-KR series?
  • Choose HG-SR102J for higher torque (4.8 Nm vs 1.3 Nm) and IP67. Choose HG-KR for lower weight and smaller size.
• What warranty and shipping do you offer?
  • 12 months warranty. Ships in 12-24 hours via FedEx, UPS, or DHL.
