New Hygienic Integrated Electric Actuators Provide Modular Clean-in-place Solutions

The Tolomatic IMA-S stainless-steel integrated servo actuator is designed for the most demanding of food and beverage processing applications.

Minneapolis – September 30, 2019 – Tolomatic IMA-S integrated electric servo actuators are designed to hygienic standards for eliminating harborage points and preventing bacterial growth. The 316 stainless-steel construction provides excellent corrosion resistance and withstands high pressure, high temperature and caustic wash-down. With its hygienic design and IP69k ingress protection rating, the IMA-S meets clean-in-place requirements, allowing machine designers to achieve open machine designs and eliminate shrouding required to house standard actuators.

The hollow rotor servo motor is integrated into the actuator housing. This creates a compact, hygienic motion module that facilitates conversion of pneumatic and hydraulic cylinder systems by increasing efficiency, motion control and eliminating product contamination risks.

The hygienic IMA-S series offers forces up to 11.1 kN (2500 lbf), stroke lengths up to 450 mm (18 inches) and options for planetary roller screws or ball screws. A proprietary lubrication feature helps extend service life.

Feedback options include multi-turn absolute encoders (Hiperface DSL, Hiperface Sin-Cos, EnDat 2.2), incremental encoder, and a resolver to integrate with most PLC or control system. Motor files for Rockwell Automation (Allen Bradley) Kinetix motion platform are also available for quick integration. Flexible mounting options include front face, front flange and rear clevis. Additional options include a replaceable IP69k seal cartridge, approved FDA seal material, and EHEDG fasteners. 

 “The IMA-S was designed to meet food and beverage industry trends towards more open machine designs requiring hygienic, clean-in-place, linear motion solutions,” said Daniel Schmit, product manager, Tolomatic, Inc. “Throughout the design process, Tolomatic analyzed and incorporated feedback from industry-leading OEMs into the design, ensuring the IMA-S eliminates many of the challenges and concerns the industry sees with standard actuators and historical fluid power
