Servo kits ILM85x26470 W | 2.9 Nm | 1560 rpm | 48 V

Frameless, hollow-shaft 85x26 stator-rotor kits for structurally integrated drive engineering. Discover original TQ-RoboDrive products for market-leading torque density and maximum freedom of design.

Frameless Motor ILM85
  • Highest design freedom through installation kits
  • Hollow shaft capability
  • Low voltage 12V - 48V
  • High torque density and dynamics
  • Redundant winding design available
  • Low-loss design through highest copper filling factor through orthocyclic single-pole winding
  • Thermally optimal actuator design through structural integration
  • Weight- and space-optimized drive design through system design through load collective
The ILM Series of frameless, stator-rotor installation kits from TQ-RoboDrive utilize integrated drive engineering originally developed by the German Aerospace Center (DLR).
The motors deliver market-leading torque density, unsurpassed precision and excellent overload capability in an exceptionally compact design for applications in extremely demanding environments.
