❓ Frequently Asked Questions (FAQ)

• Q1: Does HG-MR23B work without a brake power supply?
  • A1: No. The electromagnetic brake needs 24VDC to release. If you remove power, the brake engages and holds the shaft. Always control brake via relay or drive output.
• Q2: Can I use this motor in a wet or oily environment?
  • A2: Not recommended. This model has no oil seal. It is best for dry, clean indoor areas. For dusty or wet places, choose IP65 rated motors like HG-KR series.
• Q3: What is the difference between HG-MR23B and HG-KR23BJ?
  • A3: Both are 200W. HG-MR23B has ultra-low inertia (faster response) and no oil seal. HG-KR23BJ has low inertia + IP65 protection + absolute encoder. Choose MR23B for super fast small moves; choose KR23BJ for harsh environments.
• Q4: How do I select the right servo drive for HG-MR23B?
  • A4: Use Mitsubishi MR-J4-20B or MR-J5-20B. Rated current of drive must be ≥1.5A (continuous). The drive should support 200V class and brake control output. Contact us if unsure.
• Q5: What is your return policy and warranty support?
  • A5: We provide 12-month warranty from invoice date. If failure occurs under normal use, we replace or repair. We ship replacement within 24 hours. Return shipping covered for defects. For sizing mistakes, contact sales@powergearx.com for exchange help.

📘 Buying Guide – Is HG-MR23B Right for You?

• ▪ Choose HG-MR23B if
  • ▪ You need super fast start/stop (ultra-low inertia)
  • ▪ Your machine runs in a clean, dry factory
  • ▪ You want a built-in holding brake for safety
  • ▪ Your load requires 0.64 Nm or less continuous torque
  • ▪ You have 200VAC power available
• ▪ Avoid if
  • ▪ Environment has oil mist or water splashes (no oil seal)
  • ▪ You need absolute encoder feedback – this motor uses incremental encoder (standard).
• ▪ Pro tip
  • ▪ Always buy a compatible drive and cable together. We recommend MR-J4-20B + MR-J3ENCBL5M cable. This saves setup time.
