Servo-Kits ILM25x04 77 W | 0.033 Nm | 22378 rpm | 24 V

Frameless, hollow-shaft ILM25x04 stator-rotor kits with market-leading torque density and maximum freedom of design for structurally integrated drive engineering.

frameless motors ilm25
  • Maximum design freedom thanks to frameless installation kits
  • Hollow-shaft capability
  • Low-voltage operation (12–24 V)
  • Highest torque density and dynamic performance
  • Low-loss design enabled by an exceptionally high copper fill factor using orthocyclic single-pole winding
  • Thermally optimized actuator design through structural integration and thermally conductive epoxy potting
  • Weight- and space-optimized drive system design based on load profile analysis
  • Excellent controllability due to high bandwidth and lowest harmonic distortion / ripple
With the stator-rotor installation kits of the ILM series RoboDrive offers solutions for structurally integrated drive engineering. The RoboDrive technology provides the highest power density at maximum torque range and overload capability in a compact design.
The variable concept offers solutions for a variety of demanding drive applications. On request alternative voltage levels and customized torque-speed characteristics can be realized. The implementation of customer-specific solutions to achieve a compact and thermally optimized design is supported by detailed documentation, engineering services based on the RoboDrive development expertise.
