Wittenstein - premo - Rotary Servo Actuator

Absolute precision meets perfect movement: premo combines precision with motion – as efficiently as never before.

The first fully scalable servo-actuator platform is an uncompromising flexibility from the viewpoint of the user. The result is a modular system that is significantly more versatile and more individual with regard to performance for the most diverse applications, that meets almost all the challenges of automation, integration and industry specification. The core of the motor/gearbox unit is a torsionally rigid precision gearbox with low backlash and excellent torque density in conjunction with the equally powerful, permanently excited synchronous servo motor, which guarantees low cogging and a constant speed through the distributed winding.

Benefits

Maximum freedom in design:

  • Intelligent system with diverse gearbox outputs
  • short installation lengths as optimum design basis in the case of restricted floor space
  • for example, simplified design for a low interference contour even on small machines

Maximum machine reliability and investment protection:

  • Intelligent, energy-efficient product concept
  • lower investment due to smaller controllers with reduced consumption of acceleration current
  • less wiring and smaller drag chains through single-cable connection
  • higher holding torque for short emergency stop
  • reduced risk of failure thanks to functional reliability in the encoder

High bus voltage and absolute connectivity to system providers:

  • Enhanced performance through bus voltage up to 750 V DC
  • interfaces for EnDat 2.2
  • HIPERFACE DSL®
  • DRIVE-CLiQ partial in single-cable technology

Resistant and easy-to-clean actuator surface:

  • High-quality design without screw heads for optimum cleaning conditions and high value stability
