Servo-Kits ILM38x12 240 W | 0.234 Nm | 10190 rpm | 48 V

Frameless, hollow-shaft ILM38x12 stator-rotor kits with market-leading torque density and maximum freedom of design for structurally integrated drive engineering.

frameless motors ILM38x12
  • Frameless motors for highest design flexibility
  • Hollow-shaft capability
  • Low voltage 12V - 48V
  • Highest torque density and dynamics due to excellent copper fill factor
  • Low thermal losses by concentrated coils
  • Thermally optimized actuator design by structural integration and thermally conductive epoxy casting
  • Weight and installation space optimized drive system design based on load profile analysis
  • High control quality by high bandwidth and lowest harmonic component (lowest ripple)
The ILM Series of frameless, stator-rotor installation kits from TQ-RoboDrive utilize integrated drive engineering originally developed by the German Aerospace Center (DLR) for applications in extremely demanding environments.
The motors deliver market-leading torque density, unsurpassed precision and excellent overload capability in an exceptionally compact design.
