IMA Linear Servo Actuators

The IMA linear servo actuator has a unique integrated servo motor design.

The IMA is an integrated linear servo actuator featuring a unique integrated servo motor design in a compact, heavy duty package. Available in both ball and roller screw configurations, the IMA actuators provide forces up to 8,044 lbf (35.8 kN) even in high duty cycle applications. The IMA utilizes a standard linear servo motor available with many feedback types. Available in food-grade coating for sanitary wash-down applications.

Supports Third Party Drive Integration

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

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.
