Your Benefits

  • Flat, compact motor design due to maximum flexibility and installation of the motor feedback system with millimeter precision
  • Increase in dynamics and PSDI times due to the elimination of mechanical components, such as belts
  • Bearing-free technology maximizes the service life and machine availability of the overall system
  • Use of hollow shafts to feed through hoses and cables saves valuable installation space
  • Safe Motion for safe monitoring of machine movements and optimal interaction between man and machine

The trend toward highly dynamic drive systems has clearly strengthened in recent years. The STS absolute motor feedback system ensures maximum flexibility and precision when measuring the position and speed of hollow shaft motors and direct drives. The non-contact magnetic measurement principle works without causing wear. A scalable measurement system, the STS adapts to different hollow shaft diameters of the application. In addition, the STS scores points with its particularly flat design and compact dimensions, making it the ideal solution for tight installation situations. Thanks to the standardized HIPERFACE® interface, the motor feedback system can be easily integrated into nearly any industrial environment.
