IMA-S Stainless Steel Servo Motor

Designed 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 hygienic design features all 316 stainless steel construction and hygienic fasteners/cord grips which allows for open machine designs and effective clean-in-place.

Supports Third Party Drive Integration

Tolomatic’s integrated motor products (IMA & IMAS) support integration with a wide range manufacturers’ servo drives.  Check back often to our Drive Integration Resource page as we will continue to add supporting documentation and motor files.  Tolomatic also supports seamless integration with Rockwell Automation through the use of approved custom motor files (CMF) and as a Technology and Encompass partner.  See our Tech Notes on using the CMF import tool and interfacing the IMA actuator and absolute encoder with Rockwell Automation servo drives.

The product line also includes the IMA-SA model which incorporates an internal anti-rotate feature eliminating the need for an external guidance mechanism making it a perfect actuator 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. IMA-S servo motor has simple integration with Rockwell Automation (Allen-Bradley) Kinetix platform through pre-existing motor files (CMF/BLB) for easy drive and PLC integration.
