premo® SP Line rotary servo actuators

  • premo® SP Line copes with its task thanks to the high power-to-weight ratio and excellent dynamics.

  • Less prone to fouling due to smooth surfaces and conical cover without screws.

The entry level class

  • Especially suitable for positioning tasks
  • Short cycle times
  • Special benefits with moving axes: the low weight and short overall length
  • Mechanical interface with output shaft
  • Ideal for connecting couplings, toothed belt pulleys and pinions
  • In addition to the smooth shaft version, key and splined shaft versions are also available
  • Electric interface with resolver as standard

Your benefits

Improved efficiency

The low moment of inertia and high power density mean the power which is supplied is utilized more efficiently

Smaller footprint

The short installation length of the servo actuators enables a more compact design of your machine

Enhanced productivity

The increased rigidity and dynamics generate higher output in your machine

High connectivity

The wide selection of motor encoders enables connectivity to many different servo drives.
