Wittenstein axenia hygienic servo actuators

Click2Contact

Developed for use in the sterile and wet areas of production and packaging machines, Wittenstein alpha’s axenia value series motor/gearbox systems can be incorporated into open units without any additional protective measures. This not only saves time and cost in integration, but also avoids the multiple performance, process and product risks associated with enclosed or encapsulated servo actuator solutions.

axenia value servo actuators in single-cable technology complement the Wittenstein range of hygienic design and EHEDG-compliant planetary gearboxes (HDV and HDP). They are also offered in the cyber dynamic line for output ratings up to 335 W as mechatronic drive solutions for sterile applications where germs, bacteria, microorganisms and dirt pockets must be ruled out and machine components have to be cleaned fast, reliably and without residue.

Using the system toolkit provided, the hygienic servo actuators in the axenia value series can be configured in three motor sizes with a maximum acceleration torque of 32, 80 or 200 Nm and gear ratios from i=10 to i=25, depending on the desired task and the performance requirements. A holding brake, temperature sensors and analog and digital encoder systems for position and speed can be built in as options.

The exterior housing surfaces and the cable glands are made from extra-hard-wearing 1.4404/AISI 316L stainless steel. The rolled steel surfaces are very smooth with roughness of less than Ra 0.8 µm. The housing has IP69K protection to prevent the ingress of moisture during CIP or SIP cleaning or high-pressure washdown.
