WITTENSTEIN alpha axenia value series of hygienic servo actuator

Microbiologically safe, residue-free cleaning, resistant to corrosion, a hygienic system design that is suitable for integration into open machine architecture — all of these attributes are united in the hygienic servo actuators in WITTENSTEIN alpha’s axenia value series available from Treotham.

Developed for use in the sterile and wet areas of production and packaging machines, these motor/gearbox systems can be incorporated into open units without any additional protective measures.

axenia value servo actuators in single-cable technology complement the Treotham range of Hygienic Design and EHEDG-compliant Wittenstein planetary gearboxes (HDV and HDP). Treotham also offers the compact servo actuators 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 for this purpose, 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. Regarding the controller, these servo actuators in hygienic design are specified for more than 20 possible types from different manufacturers to assist with optimal connectivity.

The exterior housing surfaces and the cable glands are made from 1.4404/AISI 316L stainless steel. The rolled steel surfaces are smooth with roughness of less than Ra 0.8 µm. This minimises the risk of product adhesion and allows cleaning materials and disinfectants to be rinsed or drained off without leaving any residue. The housing has IP69K protection to prevent the ingress of moisture during CIP or SIP cleaning or when using a high-pressure cleaner. The sealing materials conform to EHEDG and FDA requirements for hygienic design.
