⚙️ What it means in practice

  • This is a high-torque direct-drive motor used for heavy rotary tables (large machining centers, 4th/5th axis, indexing tables).
  • Works only as a pair:
    • TM-RBP150G20 (stator)
    • TM-RBS150G20 (rotor)
  • Designed for low-speed, very high torque, backlash-free motion.

⚠️ Important notes

  • Requires liquid cooling to reach rated torque continuously.
  • Rotor is strongly magnetized → very high attraction force during assembly.
  • Must maintain precise air gap (~1 mm class design) for safe operation.
  • IP00 means it is not sealed → must be installed inside a protected machine enclosure.
