WITTENSTEIN alpha

premo – The new, powerful Actuator Platform

  • premo is the first fully scalable actuator platform: highly flexible and secure usage, energy efficient and unique connectivity, productivity and precision.
  • premo base line – the basic class Optimum performance for all positioning tasks, short cycle times through low backlash and high rigidity at very good positioning accuracy
  • premo advanced line – the dynamic class Precision for positioning and processing tasks, high torsional rigidity and lowest backlash enable high acceleration and control quality
  • premo high line – the extra class Versatile in almost all sectors, maximum power density with high torsional rigidity and radial forces

Absolute Precision meets perfect Movement: premo combines precision with motion – more efficient than ever.

The central idea behind the first fully scalable servo-actuator platform of WITTENSTEIN is an uncompromising flexibility from the viewpoint of the user.The core of the motor/gearbox unit is a torsionally rigid, precision gearbox with low backlash and excellent torque density in the combination with the equally powerful, permanent magnet servo motor which guarantees low cogging and a minimal volicity ripple through the distributed winding.

Individual upgrading of all lines possible through diverse options.

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

Feedback systems:
In addition to the standard versionare available: EnDAT 2.1/2.2, HIPERFACE®, HIPERFACE® DSL and DRIVE-CLiQ. 

Temperature sensor:
Choose from PTC or PT1000.

Electrical connection:
Straight or right-angled version and single-cable connection for DSL protocol.

Pin assignment:
For a number of servo controllers, we offer special pin assignments for power and signal.

Operating voltage:
Depending on the application and servo regulator, windings for 24, 48, 320 and 560 V DC are available.

Lubrication:
Select from the standard lubrication with oil or grease as well as foodstuff-compatible grease and oil.

Gearbox model:
Within the relevant line, there are different versions of output and housing flange Maximum backlash In order to improve precision, the gearbox backlash can be optionally reduced.

Holding brake:
A suitable permanent-magnet holding brake adapted to the motor power is available.

  • WITTENSTEIN alpha rack and pinion systems enable the coupling of servo actuator, pinion and rack in the most effective manner. Available are High Performance pinion for high line and Premium Class RTP pinion for advanced line, Performance and High Performance Class racks

  • The simco® drive servo amplifier controls sine-commutated servo motors and is available as a switch cabinet version with protection class IP20 and a decentralized version with protection class IP65. With a voltage range of 24 and 48 V DC and a short-term peak output of up to 1 kW, the simco® drive servo amplifier is suitable for high-precision applications

  • The special system cables support the high performance of the machine most effectively and therefore represent the optimal system expansion „directly from the manufacturer“. All the cables are characterized by excellent quality and are compatible with drag chains
