Helical-Worm Servo Gearmotors


The S..CMP.. helical-worm servo gearmotors have a torque range of 92 Nm to 520 Nm. As angular drives they are especially space-saving and reduce the expenditure for valuable installation space.
The helical-worm servo gearmotors are designed in such a way that they guarantee you a low-noise system environment. Moreover, these gearmotors offer you excellent attenuation properties for the operation of your systems with low levels of vibration. This is because of the longitudinal application of force on the input shaft. This allows torque impulses to be prevented effectively and for optimum results in terms of running smoothness and noise reduction to be achieved.
Both the gear unit, and the synchronous servomotor are based on their modular system. This enables you to have fully individual configuration possibilities for each application. One thing is certain – Our servo gearmotors are real specialists for very specific requirements.


Synchronous servomotor

  • Highest dynamic characteristics throughout the entire CMP.. series thanks to the low-inertia rotor design and high overload capacity of the motors
  • Performance-optimised and extremely compact design thanks to the latest winding and magnet technology
  • Standstill torques from 0.5 Nm to 95 Nm
  • Optional CMPZ.. motor variant with increased rotor inertia for all applications with high load moments of inertia
  • High quality of concentric running characteristics
  • Direct mounting of the motor on a gear unit from our modular gear unit system
