IMA-S Stainless Steel Servo Motor

Hygienic servo actuators for the most demanding food and beverage applications

The IMA-S is a hygienically designed integrated electric servo actuator for the food and beverage processing industry. The IP69K rated design features all 316 stainless steel construction and both hygienic fasteners and cord grips, ideal for open machine designs and effective clean-in-place.

Supports Third Party Drive Integration

Tolomatic’s stainless steel integrated motor actuator — IMA-S — supports integration with a wide range manufacturers’ servo drives.

Tolomatic’s integrated motor products (IMA & IMAS) support integration with a wide range manufacturers’ servo drives. We also support seamless integration with Rockwell Automation through the use of approved custom motor files (CMF) as a Technology and Encompass partner. You can learn more about interfacing the IMA actuator and absolute encoder with Rockwell Automation servo drives by reviewing the installation, maintenance and operation manual.

This product line includes the IMA-SA model which incorporates an option for an internal anti-rotate feature eliminating the need for an external guidance mechanism, ideal for applications such as volumetric filling and pumping.

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 systems. The hygienic, stainless steel IMA-S servo actuator easily integrates with Rockwell Automation (Allen-Bradley) Kinetix platform through pre-existing motor files (CMF/BLB) for straightforward drive and PLC integration.
